once test is completed, in
case the average value
between R+ and R- is lower
than the set limit, the
instrument gives a double

the positive result of the test
and displays a screen similar

1.
Use the arrow keys , to select the virtual Func key and set the CAL test
mode by means of the arrow keys , .
It is not necessary to confirm the selection with ENTER.
2. Short the leads of the measurement cables as in Fig. 7 making sure that the
conductive parts of alligator clips are well in contact.
3.
Press the GO/STOP key on the instrument or the START key on remote
probe. The instrument starts the calibration procedure of the cables
immediately followed by the verification of the compensated value.
CAUTION
If message “Measuring…” appears on the display, the instrument is
performing measurement. If message “Waiting verify” appears on the
display, the instrument is verifying the calibrated value. During this whole
stage, do not unshort the test leads of the instrument.
