Digital Multimeter
5040
To prevent excess current from flowing through your
meter, always disconnect the test leads from the circuit
under test whenever you change DMM functions, Set
your meter to the correct function, say current and its
highest range for the setting, say 10A. Next, connect the
test leads before you apply power to the circuit. To be
safe, start by setting your meter to its highest range first.
Nearly every electrical engineer has a hand held
digital multimeter (DMM). We sometimes take them for
granted, until we damage them or “burn them out” if you
incorrectly connect your DMM to a circuit or have the
DMM on wrong setting, you damage the meter and
possibly hurt yourself. You can also get into trouble if you
try to measure the voltage across a charged capacitor.
DMM users frequently burn their meters by trying to
measure current the same way as they measure voltage,
Remember, you measure voltage across a circuit, and
current through a circuit. When you use the current input,
your DMM becomes a lower impedance circuit element.
If you accidentally connect this low impedance path
across your circuit, you’ll effectively short-circuit it. You
can, therefore send high current through your meter and
severely damage it. Unless the meter has a fused input,
y o u c a n e v e n g e t a n e x p l o s i o n o r f i r e .
If you are measuring current in industrial
environment, you can easily exceed those ratings. The
best way to avoid damage is to use a clamp meter or to
connect a clamp attachment to your DMM.
Even if you correctly insert your DMM into the circuit,
you can still damage your meter. Don’t try to measure
current in excess of your meter’s capacity. Handheld
DMMs usually have a maximum current rating of 10A or
20A.
TAKE MEASUREMENT CAREFULLY AND YOU’LL
SPARE YOUR METER AND YOURSELF, SOME PAIN

NMRR is the DMM’s ability to reject unwanted AC
noise effect which can cause inaccurate DC
measurements. NMRR is typically specified in
terms of dB (decibel). This series has a NMRR
specification of >60dB at 50 and 60Hz, which
means a good ability to reject the effect of AC noise
in DC measurements.
Common mode voltage is voltage present on both the
COM and VOLTAGE input terminals of a DMM with
respect to ground. CMRR is the DMM’s ability to
reject common mode voltage effect which can cause
digit rolling or offset in voltage measurements. This
series has a CMRR specifications of >60dB at DC
60Hz in ACV function; and >120dB at DC, 50 and
60Hz in DCV function. If neither NMRR nor CMRR
specification is specified, a DMM’s performance will
be uncertain.

Crest Factor is the ratio of the Crest (instantaneous
peak) value to the True RMS value, and is commonly
used to define the dynamic range of a true RMS DMM.
A pure sinusodial waveform has a Crest Factor of 1.4. A
badly distorted sinusoidal waveform normally has a
much higher Crest Factor.

2) Circuit breakers to trip prematurely.
True RMS is a term which identifies a DMM that responds
accurately to the effective RMS value regardless of the
waveforms such as : square, sawtooth, triangle, pulse
trains, spikes, as well as distorted waveforms with the
presences of harmonics.
Harmonics may cause :
3) Fuses to blow
4) Neutrals to overheat due to the triplen
harmonics present on the neutral.
1) Overheated transformers, generators and
motors to burn out faster than normal.
5) Bus bars and electrical panels to vibrate.
RMS (Root-Mean-Square) is the term used to describe
the effective or equivalent DC value of an AC signal. Most
digital multimeters use average sensing RMS calibrated
technique to measure RMS values of AC signals. The
technique is to obtain the average value by rectifying and
filtering the AC signal. The average value is then scaled
upward (calibrated) to read the RMS value of a sine wave.
In measuring pure sinusoidal waveform, this technique is
fast, accurate, and cost effective. In measuring pure
sinusoidal waveforms, however, significant errors can be
introduced because of different scaling factors relating
average to RMS values.
The analog bar graph provides a visual indication of
measurement like a traditional analog meter needle. It is
excellent in detecting faulty contacts, identifying
potentiometer clicks, and indicating signal spikes during
adjustments.

Normal forward voltage drop (forward biased) for a
good silicon diode is between 0.400V to 0.900V. A
reading higher than that indicates a leaky diode
(defective). A zero reading indicates shorted diode
(defective). An OL indicates an open diode
(defective). Reverse the test leads connections
(reverse biased) across the diode. The display shows
OL if the diode is good. Any other readings indicate
the diode is resistive or shorted (defective).

Note :
input sensitivity varies automatically with function
range selected before activating the Hz function.
mV function has the highest (300 mV) and the
1000V range has the lowest (300V). It is
recommended to first measure the signal voltage
(or current) level then activate the Hz function in
that voltage (or current) range to automatically set
the most appropriate trigger level. You can also
press the RANGE button momentarily to select
another trigger level manually. If the Hz reading
becomes unstable, select lower sensitivity to avoid
electrical noise. If the reading shows zero, select
higher sensitivity.

The instrument equips with an optical isolated
interface port at the meter back for data
communication. PC interface kit (Rs232 optical
adapter cable + RS232C software floppies) is
required to connect the meter to the PC
computer. The RS232 Data Recording System
software equips with a digital meter, an analog
meter, a comparator meter, and a Data
Graphical recorder display. Refer to the
README file in the interface kit for further
Details.

Beep-Jack™ Input Warning
The meter beeps as well as displays “InEr” to warn
the user against possible damage to the meter due
to improper connections to the mA, mA, or A input
jacks when other function (like voltage function) is
selected.
Set Beeper Off
Press the Hz button while turning the meter on to
disable the Beeper feature.
Auto Power Off (APO)
The Auto Power Off (APO) mode turns the meter off
automatically to extend battery life after
approximately 17 minutes of no activities. Activites
are speciafied as : 1) Rotary switch or push button
operations and 2) Significant measuring data
readings of around 10% of range. That is, the meter
will intelligently avoid entering the APO mode when
it is under normal measurements. To wake up the
meter from APO, press the SELECT button
momentarily or turn the rotary switch to the OFF
position and then turn back on again. Always turn
the rotary switch to the OFF position when the
meter is not in use.
Disabling Auto Power Off
Press the RANGE button while turning the meter on
to disable the Auto Power Off (APO) feature.

Warning
Cleaning and storage
Maintenance
If the instrument fails to operate, check battery,
fuses, leads, etc., and replace as necessary. Double
check operating procedure as described in this user’s
manual.
Trouble Shooting
To avoid electrical shock, disconnect the meter from
any circuit, remove the test leads from the input jacks
and turn OFF the meter before opening the case. Do
not operate with open case. Install only the same type
of fuse or equivalent.
Periodically wipe the case with a damp cloth and mild
detergent; do not use abrasives or solvents. If the
meter is not to be used for periods of longer than 60
days, remove the battery and store it separately
If the instrument voltage-resistance input terminal
has been subjected to high voltage transient (caused
by lighting or switching surge to the system) by
accident or abnormal conditions of operation, the
series fusible resistors will be blown off (become high
impedance) like fuses to protect the user and the
instrument. Most measuring functions through this
terminal will then be open circuit. Refer to the
Warranty section for obtaining warranty and repairing
service.
