Devices like welding transformer, car ignition system, etc. could produce stray
electromagnetic fields which could adulterate the result of a measurement.
DC Voltage measurement
Attention: Avoid voltage measuring in electrical circuits while motors are
switched on or off. The stress‐spikes can damage the instrument..
1.
Set the rotary switch to the DCV ‐ Position
2.
Connect the black test prod to the negative pole and the red test prod to
the positive pole of the circuit to be tested.
3.
Once the reading stabilizes, read the value. If the polarity is twisted a
"Minus sign" is displayed.
AC Voltage measurement
Attention: Hazardous voltage! The probes may not be long enough to
touch the hot parts in some 230V wall sockets as they are deep inside. As
a result, the reading can show 0 volts. Make sure that the probes touch
the metallic contacts in the socket before assuming that voltage has not
been applied.
