6.1.1. Calibrating the test leads ("CAL" Mode)
1. Connect the black and yellow test leads to T1 and T4 input terminals
respectively.
T1 T2 T3 T4
I1 I2 I3
(V1) (V2) (V3) (COM)
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 black cable.
3. Short-circuit the measuring cable ends making sure that the conductive parts of the
alligator clips make good contact with each other (see previous picture).
4. Press the F2 key. The instrument performs the calibration.
WARNING
Never disconnect the test leads when the message "MEASURING" is
displayed.

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 performs the calibration only if the resistance of the test leads is
lower than 5
