Caution
ONE SIDE OF ALMOST ALL POWER DISTRIBUTION SYSTEMS IS
GROUNDED. EXTREME CAUTION MUST BE USED IF DIRECT
MEASUREMENT OF POWER LINE VOLTAGES IS ATTEMPTED.
IF THE GROUND CLIP LEAD IS ACCIDENTALLY CONNECTED TO
THE UNGROUNDED SIDE OF THE LINE, SEVERE DAMAGE TO
THE 4 1 OC IS POSSIBLE BECAUSE OF THE SHORT CIRCUIT
CREATED. POWER LINE VOLTAGES CAN BE SAFELY MEASURED
BY USING THE PROBE TIP ONLY. CONTACTING THE GROUNDED
POWER CONDUCTOR WILL GIVE A READING OF 0 VOLTS WHILE
CONTACTING THE UNGROUNDED LEAD WILL GIVE FULL LINE
VOLTAGE READING.

GENERAL INFORMATION
1-1. DESCRIPTION.
1-2. The Hewlett-Packard Model 41 OC Electronic
Voltmeter can be used to measure DC voltage and DC
current; AC voltage and resistance. Positive and
negative DC voltages from 10 millivolts to 1500 volts
and positive and negative DC currents from 1.5 micro-
amperes to 150 milliamperes can be measured full
scale. Resistance from 10 ohms to 10 megohms full
scale can be measured with an accuracy of ?5% of
reading at midscale; resistance from 0.2 ohms to 500
megohms can be measured with reduced accuracy.
The Model 410C Electronic Voltmeter is shown in
Figure 1-1; the specifications are given in Table 1-1.
1-3. With the Model 11036A detachable AC Probe,
the Voltmeter can be used to measure AC voltage from
20 cps to 700 Mc. From 20 cps to 100 Mc, AC voltage
from 0.5 to 300 volts can be measured; from 100 Mc
to 700 Mc, refer to Figure 3-5 for maximum AC vol-
tage that can be applied to the AC Probe. For additi-
onal information on the AC Probe, refer to Paragraph
1-8.
1-4. INSTRUMENT IDENTIFICATION.
1-5. Hewlett-Packard uses a two section, eight-digit
serial number (000-00000). The serial number is on
a plate attached to the rear panel of the instrument.
If the first three digits of the serial number on your
instrument do not agree with those on the title page
of this manual, Appendix C, Backdating Changes will
define differences between your instrument and the
Model 410C described in this manual.
1-6. ACCESSORIES AVAILABLE.
1-7. Accessories are available that extend the AC
and DC measuring capabilities of the Voltmeter. A
description of these accessories and their specifica-
tions is given below.
1-8. MODEL 11036A AC PROBE. This accessory,
when used with the Model 410C, permits AC voltage
measurements from 0.5 volts rms to 300 volts rms,
full scale over a frequency range of 20 cps to 700 Mc.
Reference calibration accuracy at 400 cps (sinusoidal)
is ?3% of full scale. Frequency response is ?10% from
20 cps to 700 Mc, with indications obtainable to 3000
Mc. Frequency response at 100 Mc is within ?2%.
The Model 11036A responds to the positive-peak-
above-average value of the signal applied. The Model
410C is calibrated to read in RMS volts, for sine wave
inputs.
1-9. MODEL 11039A CAPACITIVE VOLTAGE DIVI-
DER. This accessory (formerly the Model 452A)
extends the AC voltage range of the Model 410C to 25
kv. The divider permits measurements of extremely
high AC voltage such as encountered in dielectric
heating equipment, etc., over a frequency range of
25 cps to 20 Mc. A fixed gap is provided so that break-
down will occur if the applied voltage exceeds 28 kv at
low frequencies. Voltage division is 1000:1, ?3%, and
input capacity is 15 picofarads. A Model 11018A
Adapter is also required to connect the Model 11036A
AC Probe to the shielded banana plug fitting of the
divider.
1-10. MODEL 11040A CAPACITY DIVIDER. This
accessory (formerly the Model 453A) extends theAC
voltage range of the Voltmeter to 2000 volts RMS. The
divider is for use at frequencies above 10 kc. Voltage
division is 100:1, ?1%, and input capacity is approxi-
mately 2 picofarads.
1-11. MODEL 11042A PROBE T CONNECTOR. This
accessory (formerly the Model 455A) is used for con-
necting the Model 11036A Probe across a 50-ohm
transmission line using type N connectors. The T-
joint is such that connection of the probe into a trans -
mission line will not cause a standing wave ratio
greater than 1.1 at 500 Mc and 1.2 at 1000 Mc. With
this device, measurement of power traveling through
a transmission line may be made with reasonable ac-
curacy to 1000 Mc. The usual precautions must be
takento provide accurate impedance matching and the
elimination of standing waves along the line through
which power is floating. By using a dummy load at
the receiving end of this T-joint, power output of
various devices can be measured. In many applica-
tions power going into a real load, such as an antenna,
can be conveniently measured up to 1000 Mc with good
accuracy.
1-12. MODEL 11043A TYPE N CONNECTOR. This
accessory (formerly the Model 458A) allows the AC
Probe to be connected to a 50-ohm coaxial line. The
connector uses a male type N connector and a recep-
tacle for receiving the probe. Terminating resistor
is not included.
1-13. MODEL 11045A DC DIVIDER. This accessory
extends the maximum DC voltage range of the Model
410C to 30 kv. Voltage division is 100:1, ?5%, and
input resistance is 9900 megohms. When used with
the Mode1410C, input resistance is 10,000 megohms.
This probe offers maximum safety and convenience
for measuring high voltages such as in television
equipment, etc. The maximum current drain is 2.5
microamperes.

SECTION III
OPERATION
3-1. INTRODUCTION.
3-2. The Model 410C is used to measure AC and DC
voltage, DC current, and resistance. All measure-
ment inputs are located on the front panel; a DC out-
put connector is located on the rear panel. Front
panel controls and indicators are color coded. DC
voltage, DC current and resistance knobs and indi-
cators are in black; AC voltage controls and indica-
tors are in red.
3-3. ADJUSTMENT OF MECHANICAL ZERO.
3-4. The procedure for adjustment of mechanical
zero is given in Section V.
3-5. FRONT AND REAR PANEL DESCRIPTION.
3-6. Figure 3-1 describes the function of all front
and rear panel controls, connectors and indicators.
The description of each control, connector and indi-
cator is keyed to a drawing which accompanies the
figure.
.1?4 1416?' 3-7. OPERATING PROCEDURES.
3-8. There are five operating procedures: DC Volt-
age Measurements, Figure 3-2; DC Current Measure-
ments, Figure 3-3; AC Voltage Measurements, Fig-
ure 3-4; Resistance Measurements, Figure 3-7; and
Measuring DC Current in Nano-amperes, Figure 3-8.
Note
Ageing of the neon lamps in the chopper
assembly can cause a change in chopper
frequency which produces a slight osci-
llatory movement of meter pointer. If
this oscillatory movement is observed,
rotate Osc Freq Adj A3R5 (see Paragra-
graph 5-2 8) in the ccw direction until
oscillation of pointer stops.
3-9. DC VOLTAGE MEASUREMENTS (Figure 3-2).
3-10. The Model 410C is normally floating; however
a shorting bar can be connected at the DC AMPLIFIER
OUTPUT connector on the rear panel. When the instru-
ment is floating, the COM Lead should not be connected
to voltages greater than 400 volts.
:3-11. DC CURRENT MEASUREMENTS (Figure 3-3).
3-12. General instructions for the measurement of
DC current are the same as those given for DC volt-
age measurements, Paragraph 3-9.
3-13. AC VOLTAGE MEASUREMENTS (Figure 3-4).
ONE SIDE OF ALMOST ALL POWER
DISTRIBUTION SYSTEMS IS GROUNDED.
EXTREME CAUTION MUST BE USED IF
DIRECT MEASUREMENT OF POWER
LINE VOLTAGES IS ATTEMPTED. IF
THE GROUND CLIP LEADIS ACCIDEN-
TALLY CONNECTED TO THE UN-
GROUNDED SIDE OF THE LINE . SEVERE
DAMAGE TO THE 410C IS POSSIBLE
BECAUSE OF THE SHORT CIRCUIT
CREATED. POWER LINE VOLTAGES
CAN BE SAFELYMEASURED BY USING
THE PROBE TIP ONLY. CONTACTING
THE GROUNDED POWER CONDUCTOR
WILL GIVE A READING OF 0 VOLTS
WHILE CONTACTING THE UN-
GROUNDED LEAD WILL GIVE FULL
VOLTAGE READING.
3-14. Although the Model 410C indicates a full scale
AC range of 500 volts, the optional Model 11036A AC
Probe should not be connected to AC voltages in ex-
cess of 300 volts RMS. AC voltage referenced to a
DC voltage may be measured, but the AC Probe clip
(alligator type) must be connected to the ground (-1-..)
of the circuit under test.
WHEN MEASURING AC REFERENCED
TO DC, THE PEAK AC VOLTAGE PLUS
DC VOLTAGE CONNECTED TO THE
PROBE MUST NOT EXCEED 420 VOLTS.
3-15. PRECAUTIONS WHEN MEASURING AC VOLT-
AGE.
3-16. Special considerations must be kept in mind
when makingAC voltage measurements. These con-
siderations are discussed in the following paragraphs.
3-17. GENERAL CONSIDERATION OF COMPLEX
WAVEFORMS. Waveforms containing appreciable
harmonics or spurious voltages will introduce error
in the meter indication since the meter has been cali-
brated to read RMS values of true sine waves while
the Model 11036A Probe is a peak-above-average
responding device. The magnitude of error that may
be expected when harmonics are present on the mea-
sured waveform is indicated in Table 3-1.
3-18. VOLTAGE MEASUREMENTS AT FREQUEN-
CIES BELOW 50 CYCLES/SECOND. Voltage mea-
surements at frequencies as low as 10 cycles per

3-19. VOLTAGE MEASUREMENT AT HIGH FRE-
QUENCIES. At frequencies above 100 megacycles
the distance between the point of voltage measure-
ment and anode of the probe diode must be made as
short as possible. If feasible, substitute a small disc
type capacitor of approximately 50 picofarads for the
removable tip on the probe. Solder one terminal of
the button capacitor to the measurement point in the
circuit and not to the probe contact. The probe con-
tact ( with tip removed ) can then contact the other
terminal of the capacitor for the measurement.
3-20. At frequencies above 100 megacycles consid-
erable voltage may be built up across ground leads
and along various part of a grounding plane. Con-
sequently, to avoid erroneous readings when measur-
ing medium and high frequency circuits, use the
ground clip lead on the shell of the probe to connect
the circuit ground. In some cases at the higher fre-
quencies it maybe necessary to shorten the grounding
lead on the probe.
3-21. For all measurements at higher frequencies,
hold the molded nose of the probe as far from the ex-
ternal ground plane or from object at ground potential
as can conveniently be done. Under typical conditions,
this practice will keep the input capacitance several
tenths of a picofarad lower than otherwise.
3-22. For measurements above approximately 250
megacycles it is almost mandatory that measurements
be made on voltages which are confined to coaxial
transmission line circuits. For applications of this
type, the Model 11036A Probe is particularly suitable
because the physical configuration of the diode and
?*tmilso' probe is that of a concentric line, and with a few pre-
cautions it can be connected to typical coaxial trans-
mission line circuits with little difficulty.
Section In
Paragraphs 3-19 to 3-27 and Table 3-1
3-23. To connect the probe into an existing coaxial
transmission line, cut the line away so the center con-
ductor of the line is exposed through a hole large
enough to clear the body of the probe. The nose of the
probe should be removed for this type of measurement.
Connect one terminal of a button-type capacitor of ap-
proximately 50 picofarads to the center conductor of
the coaxial line so that the other terminal of the capa-
citor will contact the anode connection of the probe.
A close-fitting metal shield or bushing should be ar-
ranged to ground the outer cylinder of the probe to the
outer conductor of the transmission line. This type of
connection is likely to cause some increase in the
standing wave ratio of the line at higher frequencies.
The Model 11042A Probe T Connector is designed to
do this job with SWR or less than 1.1 at 500 Mc (see
Paragraph 1-11).
3-24. EFFECT OF PARASITICS ON VOLTAGE
READINGS. At frequencies above 500 megacycles,
leads or portions of circuits often resonate at fre-
quencies two, three, or four times the fundamental
of the voltage being measured. These harmonics may
cause serious errors in the meter reading. Owning to
the resonant rise in the probe circuit at frequencies
above 1000 megacycles, the meter may be more sen-
sitive to the harmonics than to the fundamental. To
make dependable measurements at these frequencies,
the circuits being measured must be free of all para-
sitics.
3-25. EFFECT OF DC PRESENT WITH AC SIGNAL.
When measuring an AC signal at a point where there
is a high DC potential, such as at the plate of a vacuum
tube, the high DC potential may cause small leakage
current through the blocking capacitor in the tip of the
Model 11036A AC Probe. When the AC signal under
measurement is small, the error introduced into the
reading can be significant. To avoid leakage, an addi-
tional capacitor with a dielectric such as mylar or
polystyrene which has high resistance to leakage is
required. (Use 5 picofarads or higher, and insert the
capacitor between the point of measurement and the
probe tin. 1
3-26. PULSE MEASUREMENTS.
3-27. POSITIVE PULSES.The Mode111036A AC Probe
is peak-above- average responding and clamps the
positive peak value of the applied voltage. This per-
mits the probe to be used to measure the positive-
voltage amplitude of a pulse, provided the reading ob-
tained is multiplied by a factor determined from the
following expression:

is the duration of the negative portion of the
voltage in microseconds.
K is a factor determined from the expression
R0/t1 and the graph shown as Figure 3-6,
where Ro is the source impedance of the pulse
generator in kilohms, and t1 is the duration of
the positive portion of the pulse in micro-
seconds.

Paragraphs 3-28 to 3-34
PRF is the pulse repetition frequency in pulses per
second (pps).
Suppose, for example:
t 10 microseconds
t2 - 990 microseconds
K = 0.55
= 1000 pps
To find K, assuming R0 = 2 kilohms and t1= 10 micro-
seconds: R0/4 = 2/10? = 0.2. Location0.2 onthe
X axis of the graph shown as Figure 3-6, and reading
K where X and Y axes intersect the unmarked curve. If
the ratio of R0/t1 were greater than 1, multiply the
X and Y axes by 10, and use the curve marked "R0/
' and K each X10".

Model 410C
3-29. In the case of a 10 microsecond negative pulse
(t2) and a pulse repetition frequency (PRF) of 1000 pps,
it would be 990 microseconds. Thus T?/ti would be
approximately 0, and from the graph it is seen that
K is approximately 0. The expression would then
reduce to
990
4 ( 1 + )
3-30. It can be seen that in the case of negative pulses
of short duration much smaller readings will be ob-
tained for an equivalent positive pulse. As a result,
large multiplying factors must be used and unless the
pulse voltage is large, these measurements may be
impractical.
3-31. MEASURING RESISTANCE (Figure 3-7).
3-32. Before making resistance measurements,power
must be removed from the circuit to be tested. Also,
make sure capacitors are discharged to eliminate any
residual voltage.
3-33. MEASURING DC NANO-AMPERE CURRENT
(Figure 3-8).
3-34. The Model 410C can be used to measure nano-
ampere leakage current in transistors and diodes. The
three most sensitive DC voltage measurement ranges
are used to measure DC nano-ampere currents.
