4.1.1. "CAL" Mode

1. Select the CAL mode using the FUNC key.
2. Connect the black and blue cables to the instrument input terminals T1 and T4
respectively:
Connection of instrument terminals during calibration procedure.
3. If the cables supplied with the instrument are not long enough for the measurement you can
extend the blue cable.
4. Connect the alligator clips to the cable terminals.
5. Short-circuit the measuring cable ends making sure that the conductive parts of the alligator
clips make a good contact with each other (see previous picture).
START
6. Press the START/STOP key. The instrument carries out the calibration.
STOP
Note: The instrument effects the calibration of cables with resistance lower of 5Ω.
At the end of the test
the result is stored and
used as the OFFSET
(i.e. it is subtracted
from any continuity
test performed) for all
the subsequent
measurements until a
new calibration
performed.
This screen is displayed for only 2 seconds
then the instrument emits a double beep
(indicating that the calibration is completed) and
displays the default screen relative to the
LOWΩ test under AUTO mode.
