8. Operating Instructions
Always switch OFF the device when it is not in use.
Be aware of the Safety Instructions (Chapter 3)
Please refer to the sketches on the first pages of this manual.
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.
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 (2.1) 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.
Bargraph
Bar graph has forty-one segments and is refreshed 10 times/sec. It displays 60
segments proportional to the actual reading. For example 60 V range, each
segment represents 1 Volt. The bar graph is not available at frequency, diode and
capacity measuring.
