5.2
Shutter for input sockets
The shutter prevents the simultaneous connection of the test leads for the multimeter function
and the connection of the thermocouples for temperature measurement. Slide the switch upwards
to use the multimeter function. To use the temperature measurement function, slide the switch
down.
Attention!
The shutter is a safety feature that prevents dangerous contact voltages. The meter must not be
operated if the shutter is defective.
5.3
Non-contact voltage detection
•
Turn the function rotary switch to any position.
•
Place the tip on the conductor to be tested. In case of multi-core conductors, run the tip
along the conductor to exclude false measurements due to twisted conductors.
•
If voltage is present, the indicator for non-contact voltage detection permanently glows
in red.
5.4
Current measurement AC / DC
Remove all test leads from the meter before making measurements with the clamp.
•
Turn the rotary function switch to the 1000 A AC/DC position.
•
Use the MODE key to select between AC and DC.
•
Open the measuring clamp, enclose the conductor to be
measured and close the clamp completely.
•
If the read value is below 50 A, turn the rotary switch to 50 A
AC/DC to improve the resolution.
5.4.1
Zeroing DC
With this function, you can set the measured value display to zero.
•
As described in chapter 5.4, select current measurement DC.
•
Press the "ZERO" key on the right side of the meter.
•
The display should now show 0000. A slight jump of the last digit is normal.
