mode depending on the rated voltage selected.

6. If the "TMR" mode was selected use the F3, F4 keys to set the duration time of

the test:

ATTENTION

Never disconnect the test leads from the circuit under test when the

message "MEASURING" is being displayed, as the circuit under test may

remain charged at a dangerous voltage. The instrument has an internal

"safety resistor" which is connect to output terminal before the end of the

test in order to discharge the parasite capacities of the installation.

7. Press the START key.

The instrument will start the test.

 MAN Mode: The test will take 4 seconds (maximum). If you keep

the START key pressed longer than 4 seconds the test

continues until the key is released.

 TMR mode: The test will take the time set. If you want to stop

the test when it's running, press the START/STOP key again.
