4.2.1.2. Mode "TIMER"

6. Use the following keys to set the duration time of the test:

Press this key to increase the duration time of the test (Tmax=999 seconds).

Press this key to decrease the duration time of the test (Tmin=10 seconds).

7. Press the START/STOP key.

The instrument effects the measurement ending when the set time has elapsed.

999 seconds → Maximum value of the test duration.

10 seconds → Minimum value of the test duration.

Note: Pressing the START/STOP key again the test gets immediately interrupted.

At the end of the test, in case the

resistance value R

ISO

detected results

to be lower than R

MAX

(depending on

the selected voltage see following table)

and the test is effected at the selected

rated voltage value, the instrument

emits a double sound signal indicating

the positive outcome of the test

displays one screen similar to the screen

alongside.

The values of measured resistance of isolation always must be confronted with the

normative limits for being able to assert if the system is to norm.

SAVING: The test can be stored pressing the SAVE key twice

(according to paragraph 5.1).

Note: The maximum resistance value R

MAX

which can be measured in mode MΩ

depends on the rated voltage selected for the test. In particular:
