Glossary of Terms for Digital Multimeters

Average sensing RMS calibrated

RMS (Root-Mean-Square) is the term used to describe the effective or equivalent
DC value of an AC signal. Most digit al multimeters use a verage sensing RM

S
ca librated technique to measure RMS values of AC signals. This technique is to
obtain the average value by rectifying and filtering the AC signal. The average
value is then scaled upward (that is, calibrated) to read the RMS value of a sine
wave. In measuring pure sinusoidal waveform, this technique is fast, accurate, and
cost effective. However, in measuring non-sinusoidal waveforms, significant errors
ca n be introduced because of different scaling factors relating average to RMS
values.

True RMS

Tru e RMS is a term wh ich identifies a DMM th at accurately responds to the
effective RMS value regardless of the waveform shapes such as square, sawtooth,
triangle, pulse trains, spikes, and transient glitches as well as distorted waveforms
with the presence of harmonics.

3. CONTROLS AND INDICATORS

54

Non-sinusoidal waveforms may cause :
– Overheated transformers, generator and motors to burn out faster than normal

– Circuit breakers to trip prematurely
– Fuses to blow
– Neutrals to be overheated due to the triplen harmonics present on the neutral
– Bus bars and electrical panels to vibrate

Crest Factor

Crest Factor is the ratio of the Crest (instantaneous peak) value to the True RMS
value, which is commonly used to define the dynamic range of a True RMS DMM.
A pure sinusoidal waveform has a Crest Factor of 1.414.
A badly distorted sinusoidal waveform normally has a much higher Crest Factor.

NMRR (Normal Mode Rejection Ratio)

NMRR is the DMM’s ability to reje ct unwanted AC noise effect which can cause
inaccurate DC measurements. NMRR is typically specified in terms of dB (decibel).
The Meter has a NMRR specification of > 60dB at 50Hz/60Hz, which means a good
ability to reject the effect of AC noise in DC measurements.

CMRR (Common Mode Rejection Ratio)

Common mode voltage is voltage existing o n both the COM and Voltage i n p u t
term inals of a DMM, with respect to ground. CMRR is a DMM’s ability to rejec

t
common mode voltage effect which can cause dig it rattle or offset in voltage
measurements. The Meter has a CMRR specification of > 60dB at DC to 60 Hz in
AC volts measurement function and > 120 dB at DC, 50Hz and 60Hz in DC volts
measurement function.

Burden Voltage

Burden voltage is a voltage drop across the input terminals of a current-measuring
device, caused by internal shunt resistance.
Burden voltage contributes measurement error, and should be as low as practical.

Temperature Coefficient

Temperature Coefficient is a factor use d to calculate t he change in indicatio n or
output of an instrument with changes in temperature.
Un compensated changes in temperature contribute uncertainty by an a mount
determined by the temperature coefficient to instrument.

Turning the Meter On
To turn the meter on, turn the rotary switch from OFF to any switch setting.

Rotary Switch

5. METER OPERATION

Voltage ( or , ) Measurements

Voltage is the difference in electrical potential between two points.
The polarity of ac (alternating current) voltage varies over time, while the polarity of
dc (direct current) voltage is constant over time.

function defaults at dc. Press SELECT button momentarily to select ac.

Range available in volts functions are :

400 mV, 4 V, 40 V, 400 V, and 1000V

When mea suring voltage, th e meter acts like a 10M (10 x 106) impedance in
parallel with the circuit. This loading effect can cause measurement errors in high­impedance circuits. In most cases, the error is negligible (0.1 % or less) if the circuit
impedance is 10 k or less.

Tips for measuring voltage

In 4 00 mV range, displayed value may fluctuate when disconnecting inpu

t

terminals. This is normal.
AC voltage measuring circuit in Model 703 is of root-mean-square (True RMS)

value system so the meter can accurately measure ac voltage of non-sinusoidal
waveforms including harmonics caused by various non-linear loads.

Tips for measuring resistance

Because the meter’s test curren t flows through all possible paths betwe en the
test probe tips, the measured value of a resistor in a circuit is often different from
the resistor’s rated value.

The test leads can add 0.1 to 0.2

of error to resistance measurements.

To measure the resistance of the leads, touch the probe tips together and read
the resistance. If necessary, you can press the REL button to automatically

subtract this value.
The resistance function can produce enough voltage to forward-bias silicon diode

or transistor junctions, causing them to conduct.
Do not use the 40 M range for measuring the in-circuit resistance to avoid this.

Whe n meas uring large resi stance, rea d in g may b e uns tabl e due to
environmentally induced electrical noise. In this case , direct ly connect the
resistor to input terminals of the meter or shield the resistor at potential of the
COM input terminal to obtain stable reading.
For resistance above 1 M , the display may take a few seconds to stabilize. This
is normal for high resistance readings..
The met er h as a circuit to p rotect the resistance range from over-voltage.
However, to prevent accidentally exceeding the protection circuit’s rating and to
ensure a correct measurement, NEVER CONNECT THE LEADS TO A SOURCE
OF VOLTAGE when the rotary switch is set to or or functions.

To improve the accuracy of dc voltage measurements taken in the presence of
ac voltages (such as, measuring the dc voltage of an amplifier in the presence of
an ac signal), measure the ac voltage first. Note the just measured ac voltage
range a nd select a d c voltage range that is the same or h igher than t he ac
voltage range. This method improves the dc voltage accuracy by preventing the
input protection circuits from being activated.

Resistance ( , , ) Measurements
(Ohms, Diode, and Continuity)

Resistance is an opposition to current flow. The unit of resistance is the ohm ( ).
The meter measures resistance by sending a small current through the circuit.

Ranges available in resistance functions are :

400.0 , 4.000 k , 40.00 k , 400.0 k , 4 M , and 40 M

Warning

To avoid the risk of electrical shock and instrument damage,
input voltages must not exceed 1000 V dc or ac (rms). Do not
attempt to take any unknown voltage measurement that may
be in excess of 1000 V dc or ac (rms).

Caution

To avoid d amaging the meter or the e quipment under test,
re move a ll power f rom the circu it a nd disch arg e all hig h­voltage capacitors before measuring resistance.

Frequency (Hz) Measurements

Frequency is the number of cycles a signal completes each second. The m eter
measures the frequency of a voltage or current signal by counting the number of
tim es the signal crosses a threshold level each second.
To measure the frequency of a voltage or current signal, press the Hz/Duty button
momentarily while measuring volts or currents.

The available frequency ranges are 5 Hz, 50 Hz, 500 Hz, 5 kHz, 50 kHz, 500 kHz,
5 MHz and 10 MHz.

Diode ( ) Test

Use the diode test to check dio des, tra nsistors, silicon controlled rectifiers (SCRs),
and othe r sem ic on ductor dev ices. T h e test sends a curr en t thr ough a
semiconductor junction, then me asures the junction’s vo ltage drop.

Normal forward voltage drop (forward biased) for a good silicon diode is between

0.4 V to 0.9 V. A reading higher than that indicates a leaky (defective ) diode. A
zero reading indica tes a shorted (defective) diode.
An indicates an open diode (d efect ive).

Reverse the test leads connectio ns ( reverse biased ) across the dio de.
The display shows if the diode is good. Any other readin gs indicate the diode
is shorted or resistive ( defective )

.

Continuity ( ) Te st

The co ntinuity function detects intermittent opens and shorts lasting as little as 1
millisecond. Th ese brief contacts cause the meter to emit a short beep. This
f

unction is convenient for checking wiring co nnectio ns and operation of switches

.

A continuous beep tone indicates a complete wire.

1312

Caution

Discharge all high-voltage capacitors before testing diodes.
Large value capacitors sh ould be dis charged through an
appropriate resistance load.

Caution

Using resistance and continuity function in a live circuit will
produce false results and may damage the instrument.
In many cases the s uspic iou s c o mpone nts mu s t be
disconnected fro m the circuit under test to obtain accurate
results.

Tips for me asuring capacitanc e

Temperature (Temp) Measure ments [Model 703 only]

Tips for measuring freque ncy

In frequency, the meter is always autoranging.
When disconnecting the input term inals, the overload sign may be displayed or
the display may unsteadily fluctuate. This is typical.

Duty Cycle Measurements

Duty Cycle (or Duty Factor) is the percentage of time a signal is above or below a
trigger level during one cycle.
The duty cycle mode is optimized for measuring the ON or OFF time of logic and
switching signals. Systems such as electronic fuel injection systems and switching
power supplies are controlled by pulses of varying width, which can be checked by
measuring duty cycle.

Press the Hz/Duty button to toggle between the Hz mode and the Duty Cycle mode
when the rotary selector knob is set to Hz (Duty), , , , or .

Capacitance Measurements

Capacitance is the ability of a component to store an electrical charge.
The unit of capacitance is the farad (F). Most capacitors are in the nanofarad (nF)
to microfarad (µF) range.

The available capacitance ranges are 40nF, 400 nF, 4 µF, 40 µF, and 100 µF.

1514

Caution

To avoid damaging the meter or the equipment under test,
remove a ll power fro m the circuit and discharge a ll high­voltage capacitors before measuring capacitance.
Large value ca pacitors should be discharged through an
appropriate resistance load. Use the dc voltage function to
confirm that the capacitor is discharged.

In capacit ance, the Meter is always

4 . Turn on power to the circuit and read the display.
5 . After measuring current, t urn off power to th e circuit and discharge all high-

voltage capacitors. Dis connect the meter and restore the circu it t o normal
o p e r a t i o n .

Tips for measur ing current

When measuring a 3-phase syste m, special attention should be taken to the
phase to phase voltage which is significantly higher than t he phase to earth
volt age. To a vo id e xceedin g the voltage rat in g of t he protecti on fuse(s)
accidentally, always consider the phase to phase voltage as the working voltage
for the protection fuse(s).
When measuring current, the meter’s internal shunt resistors develop a voltage
across the meter’s terminals called “burden voltage”.
This voltage drop may affect precision circuits or measurements.

Current ( , , ) Measurements

Current is the flow of electrons through a conductor. To measure current, you must
open the circuit under test, then place the meter in series with the circuit.

The available current ra nges are :

400.0 µA, 4000 µA, 40.00 mA, 400.0 mA, 4.000 A, and 10.00 A
The meter defaults at d c. Press S E L E C T button momentarily to select a c .

To measure dc or

ac current,

1 . Turn off power to the circuit and discharge all high-voltage capacito rs.
2 .Insert the black le ad into the C O M terminal and the red lead into an input

terminal appropriate for the me asurement range as the following table.

To avoid blowing the meter’s 440 mA fuse, use the mAµA terminal only if you are sure the
current is less than 400 mA.

3 . Open the current path to be t ested. Touch the red probe to the more positive

side of the break and touch the black probe to the more negative side of th e
break. (Reversing the leads will produce a negative reading, but will not damag e
the meter.)

Warning

Neve r attempt an in-circuit current measurement where the
open-circuit potential to earth is greater than 1000V. You may
damage the meter or be injured if the fuse blows during such
a measurement.

Caution

Ch eck the meter fuses before measuring current. Use the
proper t erm in als , function, and ra nge for c urrent
measurements. Never place the probes in parallel with any
circuit or component when the test leads are plugged into the
current terminals.

Press and hold the RANGE button for 2 seconds to resume auto- ranging.

Manual-ranging feature is not available in Hz (Duty), CAP, Temp , and
f u n c t i o n s .

Auto - Power - Off

The Auto-Power-Off feature automatically turns the meter off to extend battery life
after approximately 30 minutes of n o activities. To turn on the met er after Auto­Power-Off, turn the rotary switch from OFF to any function (ON).

Cleaning and Storage

Perio dica lly wipe the case with a damp cloth and mild detergent; do not use
abrasives or solvents.

Clean the input terminals as follows :

1. Turn the meter off and remove all test leads.

2. Shake out any dirt that be in the terminals.

3. Soak a new swab with alcohol and work the swab around in each terminal.
If the meter is not to be used for periods of longer than 60 days, remove the battery

and store it separately.

Battery and Fuse Replacement

The meter uses a single standard 9V battery (NEDA 1604, JIS006P, IEC 6F 22), a
1000 V/440 mA IR 10 kA fast acting F fuse (F

71

) for mAµA current input, and a 1000
V/11 A IR 10KA fast acting F fuse (F72) for A current input. The (F71) 440 mA, (F72) 11
A fuse must be replaced by qualified service personnel only.

Trouble Shooting

If the meter fails to operate e ven with th e battery or fuse replacements, check it
twice over according to operating procedure as described in this manual.

If the meter’s V/ input terminal has subjected to high voltage transient (caused by
lightning or switching su rge to the system) b y accident or abnormal operating
conditions, the series fusible resistors will be blown off like fuses in order to protect
the user and the meter. Most measuring functions through this terminal will then be
open circuit.
In this case, the series fusible resistors and the spark gaps should be replaced by
qual ified p erson nel. Ref er to the LIMITED WA RRANTY & L I MITAT ION O F
LIABILITY section for obtaining warranty or repairing service.

6. MAINTENANCE

Warning

To avoid electrical shock or personal injury, remove the test
leads and any input signals before replacing the battery or
fuses. To prevent damage or injury, install only the same type
of fuses or equivalents.
