4. Once calibration is comple-
ted, in case the detected
value is lower than 5, the
instrument gives a double
acoustic signal which signals
the positive result of the test
and displays a screen similar
to the one reported here to

5. In order to delete the compensation resistance value of the cables, it is necessary to
perform a cable calibration procedure with a resistance higher than 5 at test leads
(e.g. with open test leads).
6.2.2. Description of anomalous results
1. By using the AUTO, R+ or R-
mode, in case the detected
value is higher than the set
limit, the instrument gives a
long acoustic signal and
displays a screen similar to
the one reported here to the
side

2. By using the AUTO, R+ or R-
mode, in case the detected
value is higher than the full

detects a resistance which
prevents a current of 200mA
to circulate, it gives a long
acoustic signal and displays
a screen similar to the one
