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 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.
Measuring AC voltage
The maximum input voltage in the AC-V range is 600 V RMS. To prevent dangers through electric shocks
and/or damage to the appliance, do not take measurements of voltages of more than 600 V RMS.
Set the function switch to range "V"
To select the "AC", 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.
Measuring resistance / continuity / diode
Before carrying out each resistance measurement, make sure that the circuit to be measured is
not energized and that all condensers are deenergized.
Set the function switch to range "Ω/
"
Press the "SEL" button to switch between measuring the resistance, continuity and diode.
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.
Note: The continuity test is suitable to determine if there are short circuits / open circuits.
