8. Operating Instructions

1.
Always switch OFF the device when it is not in use..
2.
If "OL" is displayed while measuring the value exceeds the used range.
Switch to a higher range if available.
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
Attention: Avoid voltage measuring in electrical circuits while motors are
switched on or off. The stress-spikes can damage the instrument.
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.
1.
Set the rotary switch to the V= - and V~ - Position
2.
Press the MODE-button to select DC for DC voltage- respectively AC for AC
voltage measurement.
3.
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-, Hz%-, W-, Ω-jack.
4.
Touch the points of the circuit to be measured with the probes.
