8. Operating Instructions
•
Always switch OFF the device when it is not in use.
•
If "OL" is displayed while measuring the value exceeds the used range.
Switch to a higher range if available.
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.
Automatic/Manual Range selection
If the instrument is switched on it is usually in automatic mode. “Auto
range” is displayed. The instrument hereby automatically detects the
most suitable range.In most cases this position fits your needs. If you
need to manually select the range proceed as following:
1.
By pressing the “RANGE“-button you can select the range manually:
2. Press RANGE as often as needed to get to the desired range.
3. To turn on the automatic range selection again, press the RANGE
button for 2 seconds.
Relative mode (REL)
The relative measurement feature allows you to make measurements relative
to a stored reference value. A reference voltage (current, etc.) can be stored
and following measurements can be compared to this value. The displayed
value is the difference between the reference and the measured value.
