5.1 Preparation for the measurement
Attention:
Carry out insulation measurements on voltage free circuits only. Before
connecting the test leads, always make sure that the circuit to be measured is
voltage free.
Always carry out the following checks before measuring:
*
After turning on the device, check the LCD display
(„Replace Battery“ Warning must not light up in the display)
*
Check the device and the test leads for visible damage. Do
not connect kinked or damaged test leads to the device.
*
Check the continuity and resistance of the test leads with
an ohmmeter.
5.2 Insulation measurement
The insulation measuring device is switched on by turning the main
selector switch to a measuring function. The start screen shows the
battery voltage, the current version and the maximum test voltage
of the measuring device. After the start up screen the preset
measurement function is shown on the LCD screen.
If the test leads are applied to the object to be measured and a
voltage is detected by the device, the warning "HV Warning" lights
up on the display.
To measure the insulation resistance, select the desired measuring
function using the rotary selector switch. Connect the test leads to
the object to be measured and ensure that the connections have
been made correctly. To start this measurement, press the test
button. The device reminds you to ensure that the test leads have
been attached to the device under test.
