6.1.1. Calibrating the test leads ("CAL" Mode)
1. Connect the black and blue test leads to B1 and B4 input terminals
respectively.
B2 B3 B4 B1
Connection of instrument terminals during calibration procedure.
2. If the test leads supplied with the instrument are not long enough for the
measurement you can extend the blue cable.
3. Short-circuit the measuring cable ends making sure that the conductive parts of the
crocodiles make a good contact to each other (see previous picture).
4. Press the F2 key. The instrument carries out the calibration.
WARNING
Never disconnect the test leads when the message "MEASURING" is

5. At the end of the test the result is stored and used as OFFSET (that is to say
that it is subtracted from any continuity test carried out) for all the
subsequent measurements.
Note : The instrument effects the calibration only if the resistance of the test leads is
lower than 5 .
