Attention!
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.
Automatic/Manual Range selection
When the meter is switched on, it is in the auto ranging mode. The device
automatically detects the appropriate measuring range. Manual range
selection is not possible.

operation the „HOLD"-button (6) could be pressed to freeze the display
reading.
1. Press the „HOLD"-button to freeze the display reading.

function.
3. Press the „HOLD"-button again to return to standard operation.
