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 mul t imeters use average sensing RM S
calibrated 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
can be introduced because o f different scaling f actors relating average to RMS
values.
True RMS
True RMS is a term which identifies a DMM that ac curately responds to t he
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 reject unwanted A C 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 on bo t h the COM and Vo l tage input
terminals of a DMM, with respect to ground. CMRR is a DMM’s ability to rejec t
common mode voltage e f fect which can cause digit rattle or of f set 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 Coe f ficien t is a factor used to calculate the change in indication or
output of an instrument with changes in temperature.
Uncompensated changes in temperature contribu t e uncertain t y by an amount
determined by the temperature coefficient to instrument.
Turning the Meter On

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 measuring voltage, the meter acts like a 10M (10 x 10
6
) impedance in
parallel with the circuit. This loading effect can cause measurement errors in high-
impedance 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 400 mV range, displayed value may f luc t uate when disconnec t ing 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 current flows through all possible paths between 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.
When meas uring large resi s t ance, reading may be uns tabl e due to
environmentally induced elec t rical noise. In this case, directly 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 meter has a circuit t o protect t he 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.
11
10
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 and select a dc voltage range that is the same or higher than the 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 damaging the me t er or t he equipment under test,
remove all power from the circuit and discharge all high-
voltage capacitors before measuring resistance.

Frequency (Hz) Measurements
Frequency is the number of cycles a signal completes each second. The meter
measures the frequency of a vol t age or current signal by counting the number of
times t he signal crosses a threshold level each second.
To measure the frequency of a vol t age or current signal, press t he Hz/Duty button
momen t arily while measuring volts or currents.
The available f requency ranges are 5 Hz, 50 Hz, 500 Hz , 5 kHz, 50 kHz, 500 kHz,
5 MHz and 10 MHz.
Diode ( ) Test
Use the diode tes t to check diodes, transistors , silicon con t rolled rectifiers (SCRs),
and ot her semic onduct or dev ic es. T he test s ends a curr ent thr ough a
semiconductor junction, then measures the junc t ion’s voltage 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 indicates a shorted (defective) diode.
An indicates an open diode (defective).
Reverse the test leads connect ions ( reverse biased ) across the diode.
The display shows if the diode is good. Any other readings indicate the diode
is shorted or resis t ive ( defective ) .
Continuity ( ) Test
The continui t y f unction detects intermittent opens and shorts lasting as little as 1
millisecond. These brief contacts cause the meter to emit a short beep. This
f unction is convenient for checking wiring connections 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 should 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 cas es t he s u spic iou s c ompone nts mus t be
disconnected from the circuit under test to obtain accurate
results.

Tips for measuring capacitance
Temperature (Temp) Measurements [Model 703 only]
Tips for measuring frequency
In frequency, the meter is always autoranging.
When disconnec t ing the input t erminals , 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 all power from the circuit and discharge all high-
voltage capacitors before measuring capacitance.
Large value capacitors should be discharged through an
appropriate resis t ance load. Use the dc voltage function to
confirm that the capacitor is discharged.
In capacitance, the Meter is always
autoranging.
In 40 nF r ange, the readings ar e
probably unstable due to envir on-
mentally induced elec t rical noise and
floating capacity of the tes t leads .
Therefore , directly connect the object
to be measured t o the input terminals.
The meter comes wi th temperatur e
reading in either Cen t igrade or
Fahrenheit preset at t he fac t ory. The
reading mode can be changed a t the
f actory only.
The SELECT func t ion is not available
in Temperature mode.
WARNING - Do not apply
thermocoupl e to circ uit s ex ceeding
30V rms , 42.4V pe ak or 6 0V d c .
Be sure to insert the banana plug K-type
temperature bead probe TP7 with correct
+ – polari t ies. You can als o us e a
thermocoupl e probe adapter T P 1 A
(O ptio nal purc has e ) t o adapt other
standard K- t ype temperature probes.

4. Turn on power to the circuit and read the display.
5. After measuring current, turn off power to the circui t and discharge all high-
voltage capacitors . Dis connec t the meter and restore the circuit to normal
operation.
Tips for measur ing current
When measuring a 3-phase system, special at t ention should be taken to the
phase to phase voltage which is significan t ly higher than the phase t o earth
voltage. To avoid exceeding the vol t age rating of the protecti on fus e(s)
accidentally, always consider the phase to phase voltage as the working vol t age
for the protec t ion fuse(s).
When measuring current, the meter’s internal shunt resis t ors develop a vol t age
across the me t er’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 t he circuit under test, then place the me t er in series with the circuit.
The available current ranges are :
400.0 µA, 4000 µA, 40.00 mA, 400.0 mA, 4.000 A, and 10.00 A
The meter defaults a t dc. Press SELECT button momentarily to select ac.
To measure dc o r ac current,
1. Turn of f power to the circuit and discharge all high-voltage capacitors.
2. I nser t the black lead into the COM terminal and the red lead in t o an input
terminal appropriate for t he measurement 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 t han 400 mA.
3. Open the current path to be tes t ed. Touch the red probe t o the more positive
side of the break and touch the black probe to the more negative side of the
break. (Reversing the leads will produce a negative reading, but will not damage
the meter.)
Warning
Never a t tempt 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
Check the meter f uses before measuring current. Use the
prope r t ermina ls , functi on, and ra nge for c urrent
measurements. Never place the probes in parallel wi t h any
circuit or component when the test leads are plugged into the
current terminals.

P ress the bu t ton momentarily again to step through the ranges .
Press and hold the RANGE but t on for 2 seconds to resume auto- ranging.
Manual-ranging fea t ure is not available in Hz (Du t y), CAP, Temp, and
functions.
Auto - Power - Off
The Auto-Power-Off feature automatically turns the meter off to extend battery life
after approximately 30 minutes of no activities. To t urn on the meter after Auto-
Power-Off, turn the rotary switch from OFF to any function (ON).
Cleaning and Storage
Periodically wipe the case with a damp cloth and mild detergent; do no t 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/11A IR 10KA fast acting F fuse (F 72 ) for A current input. The (F 71 ) 440 mA, (F 72 ) 11
A fuse must be replaced by qualified service personnel only.
Trouble Shooting
If the meter fails to operate even wi t h the 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 surge to the system) by 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 personnel. Refer to the LIMITED WARRANT Y & LIMIT A T ION OF
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 be f ore replacing the battery or
fuses. To prevent damage or injury, install only the same type
of fuses or equivalents.
