9. Operating Instructions
Do not exceed the specified limit values in order to avoid overheating and damage. Do not
measure voltages > 600V to avoid risks of overheating and/or incorrect readings.
9.1. AC Current Measurements
1) Place the rotary switch in the desired A~ position.
2) Press the trigger to open the jaws. Put one conductor between the jaws and let them close
again, making sure that the conductor is gripped firmly.
3) The current value will appear on the display.
4) Select a higher range if the overrange indication ("1") appears on the display.
5) The meter may need a few seconds to produce a stable reading when measuring currents in
the 2A-range.
9.2. DC Voltage Measurements
1) Select the 600V
range with the range selector.
2) Connect the red test lead to the “V
Ω
”-jack and the black test lead to the “COM”-jack.
3) Connect the test leads to the circuit being tested and read the displayed value.
Note : the max. DC input voltage = 600Vdc. Measuring higher voltages may lead to damage or
electroshocks.
