DIGITAL
CLAMPMETER
MODEL - 2718
Nearly every electrical engineer has a hand
held digital clamp meter (Tongtester). We
sometimes take them for granted, until we damage
them or “burn them out”. If you incorrectly connect
your clamp meter to a circuit, or if you have the
clamp meter or 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 changed capacitor.
Clamp meter 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 clamp
meter becomes a low impedance circuit element.
Even if you correctly insert your clamp meter in
to the circuit, you can still damage you meter. Don’t
try to measure current in excess of your meter’s
capacity. Check the current capacity of the Clamp
meter.
If you are measuring current in industrial
environment to prevent excess disconnect your
test leads from the circuit under test whenever you
change Clamp meter functions. Set your meter to
the correct function, say current, and its highest
range for the setting. If the reading is small, change
the range to the next lower range till the reading can
be read with the best possible accuracy. When
measuring voltage, connect the test leads before
your apply power to your circuit. To be safe, start by
setting your meter to its highest range first.
TAKE MEASUREMENT CAREFULLY AND YOU’LL
SPARE YOUR METER AND YOURSELF, SOME PAIN

E. Testing Diodes (see figure 6)
Warning
To avoid damages to the Meter or to the devices
under test, disconnect circuit power and
discharge all the high-voltage capacitors before
testing diodes.
Use the diode test to check diodes, transistors and
other semiconductor devices. The diode test sends
a current through the semiconductor junction, then
measure the voltage drop across the junction. A
good silicon junction drops between 0.5V and 0.8V.
To test the diode out of a circuit, connect the Meter
as follows :
2. Set the rotary switch to W& press SELECT
button to select diode measurement mode.
3. For forward voltage drop readings on any semi-
conductor component, place the red test lead on
the component’s anode and place the black test
lead on the components cathode.

?When diode testing has been completed,
disconnect the connection between the testing
leads and the circuit under test and remove
testing leads from the input terminals.
Caution
In a circuit, a good diode should still produce a
forward voltage drop reading of 0.5V to 0.8;
however, the reverse voltage drop reading can vary
depending on the resistance of the pathways
between the probe tips.
?Connect the test leads to the proper terminals
as said above to avoid error display.
?The LCD will display OL indicating either open
circuit or wrong polarity connection.
?The unit of diode is volt (V),displaying the forward
voltage drop readings.

3. The buzzer sounds if the resistance of a
circuit under test is less than 50W
4. The buzzer may or may not sounds if the
resistance of circuit under test is between
50Wto 120W.
5. The buzzer does not sound if the resistance
of a circuit under test is higher than 120W.
Note
!The buzzer beeps once when pressing any
buttons at any rotary switch positions except at
2/20A positions if the button is valid. If the button
is not valid, it does not beep. At 2/20A rotary
switch position, the buzzer is set not to beep.
!The buzzer beeps 5 times continuously on
around 1 minute before entering the sleep mode.
When it is just before entering the sleep mode,
it will have one long beep to warn you.
!The LCD displays OL indicating the circuit
being tested is open.
!When continuity testing has been completed,
disconnect the connection between the testing
leads and the circuit under test and remove
testing leads from input terminal.
G. Temperature Measurement
