CAUTION
 Disconnect any cable not strictly involved in measurement and especially
check that no cable is connected to In1 input.
 Before connecting the test leads, make sure that there is no voltage at the
ends of the conductors to be tested.
6. Connect the alligator clips and/or test leads and/or remote lead to the ends of the
conductors to be tested as in Fig. 8 and Fig. 9.
7. Press the GO/STOP key on the instrument or the START key on the remote lead. The
instrument will start the measurement.
CAUTION
During this whole stage, do not disconnect the test leads of the instrument
from the conductor under test. It could remain charged with a dangerous
voltage due to the stray capacitances in the circuit being tested.
8. Regardless of the operating mode selected, at the end of the measurement, the
instrument applies a resistance to the output leads to discharge the capacitances in the
circuit.
9. In mode:
 The final result is the minimum insulation value measured during the test
 Pressing a second time the GO/STOP key or the START key on the remote lead
stops the test before the set time has elapsed.
10. The measurement result is shown both as a numeric
value and in the analog bar graph as shown in the
screen to the side. The values of the real test voltage
and the measurement time are present on the display.
The symbol indicates the positive result of the
measurement.
Press the SAVE button or touch the icon to save
the measurement (see § 7.1).
11. At the end of the test, if the value of the measured
resistance is lower than the set limit, the screen to the
side is shown on the display.
The value is shown in red and the symbol indicates
the negative result of the measurement.
Press the SAVE button or touch the icon to save
the measurement (see § 7.1).
