TAKE MEASUREMENT CAREFULLY AND YOU’LL
SPARE YOUR METER AND YOURSELF, SOME PAIN
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 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.
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 your 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 accident 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.

SAFETY INFORMATION
The following safety information must be
observed to ensure maximum personal safety
during the operation of this meter.
1. Do not use the meter if the meter or test leads
look damaged, or if you suspect that the
meter is not operating properly.
2. This meter is not recommended for high
voltage industrial use, for example, not for
measurements of 440V AC or 600V AC
industrial power mains. The unit is intended
for use with low energy circuits to 600V
AC/DC or high energy circuit to 250V AC or
DC.
3. Turn off power to the circuit under test before
cutting, unsoldering, or breaking the circuit.
Small amounts of current can be dangerous.
4. Use caution when working above 60V DC or
30V AC rms. Such voltages pose a shock
hazard.
5. When using the probes, keep your fingers
behind the finger guards on the probes.
6. Measuring voltage which exceeds the limits of
the Clampmeter may damage the meter and
expose the operator to a shock hazard.
Always recognize the meter voltage limits as
stated on the front of the meter.

3. Touch probes to the diode. A forward-voltage
drop is about 0.6V (typical for a silicon diode).
4. Reverse probes. If the diode is good, "OL" is
displayed. If the diode is shorted, "0.000" or
another number is displayed.
5. If the diode is open, "OL" is displayed, in both
directions.
6. If the junction is measured in a circuit and a low
reading is obtained with both lead connections,
the junction may be shunted by a resistance of
less than 1kW. In this case the diode must be
