OPERATING INSTRUCTIONS

OPERATING INSTRUCTIONS
If the value set is exceeded for a longer period of time by the current being measured, heating
can occur that can impair the operating and function safety of internal circuits.
To prevent discharges and/or incorrect measurement values, do not carry out measurements on
high-voltage cables (> 600 V).

Measuring AC

Make sure that the test leads are removed from the measurement sockets.
Set the function switch to range A~.
Clasp one of the conductors to be measured with the current transformer (tong jaw). Make sure
that the tongs are fully closed.
Read the measurement value.
Using the "True RMS" function, zero compensation fluctuations of up to 30 Digits occur, however,
they do not influence the measurement value.

Measuring DC

Make sure that the test leads are removed from the measurement sockets.
Set the function switch to range A=.
Clasp the conductor to be measured with the current transformer (tong jaw) . Make sure that the
tongs are fully closed. Ensure that the polarity is correct!
Read the measurement value.
As necessary, carry out zero compensation before the measurement.
For this, open the tong jaws several times without a conductor, subsequently wait until the value
on the display has stabilized, then press the "SEL" button. The value on the display changes to
0.00 and "ZERO" appears on the display.
The last figure can fluctuate, this is not an error.

Measuring DC voltage

The maximum input voltage in the V DC range is 600 V DC.
To prevent dangers through electric shocks and/or damage to the appliance, do not take
measurements of voltages of more than 600 V DC.
Set the function switch to range"V"
To select the DC, press the button "SEL".
Insert the black and red test leads into the inputs COM and INPUT.
Apply the test leads to the circuit to be measured and read the value.
