Attention!
Due to the high sensitivity the reading sometimes shows random values if
the test leads are not connected to any signal. The reading stabilizes
when the test leads are connected to the circuit to be tested.
Avoid voltage measuring in electrical circuits while motors are switched
on or off. The stress-spikes can damage the instrument.
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.
Devices like welding transformer, car ignition system, etc. could produce
stray electromagnetic fields which could adulterate the result of a
measurement.
DC Voltage measurement / AC Voltage measurement
Attention!
DC voltage max. 1.000 V
AC voltage max. 750 V
1.
Set the rotary switch to the position V
2.
Attach the pin-plug of the black test lead to the COM-jack and the
pin-plug of the red test lead to the V-, Ω-, Hz-jack.
3.
Connect the black test prod to the negative pole and the red test prod to
the positive pole of the circuit to be tested.
4.
Once the reading stabilizes, read the value. If the polarity is twisted a
"Minus sign" is displayed. Use the HOLD function if the reading is difficult
to read.
