3.4.2 Measurement Configuration
Before connecting the ELMED ISOTEST
holiday detector and the high-
voltage impulse voltmeter, ensure that the ELMED ISOTEST
holiday de-
tector is switched off!
Fig. 2: Measurement configuration
Figure 2 shows the correct measurement configuration using an
ELMED ISOTEST
device. The device should be set up as follows:
1. Earth the impulse voltmeter by connecting the earthing cable (E) to one
of the 6mm jack
on the front.
Make a low-impedance connection to an earthing point on site
(PE/earthing conductor) using the clamping jaw of the supplied earthing
cable.
2. Earth the ISOTEST
®
device by connecting the earthing jack of the
ISOTEST
®
device to the 6 mm jack
of the impulse voltmeter.
3. Insert the adapter (A) as far as possible into the electrode clamping
device of the test handle and tighten the plastic nut.
4. For ISOTEST
®
devices with adjustable test voltage, set the voltage to
be measured.
5. Apply the adapter on the measuring surface
of the impulse
voltmeter.
6. Turn on the main switch of the impulse voltmeter and the ISOTEST
®
holiday detector.
Info:
The battery charge condition is permanently displayed
(battery level indicator)
7. Press the safety button on the test handle of the ISOTEST
®
holiday
detector.
