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 excess current from flowing
through your meter, always 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
