Note: 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.
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
Use the provided test leads to perform these measurements.
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 V - Position.
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-, A-, Ω-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.
AC Current measurement
Note: Always measure current on one conductor only.
Covering more than one conductor results in measuring differential current
(like identifying leakage current). To avoid measuring errors related to other
hot conductors, please observe maximum phase-to-phase clearance.
