The manufacturer does not assume any liability for injuries of persons or
damage to equipment if the test equipment is not properly used.
Liability lies with the operator of the equipment.
The high voltage impulse voltmeter ISOTEST HV is exclusively
to be used for the measuring of the output voltage of devices
that
work with impulse voltage on condition that the rms-value of
the output voltage in the event of short circuit does not
exceed 3 mA.
comply with the technical data (see chapter 4.4)
For measuring high voltages the rules and standards VDE 0104
(rules for testing stations and laboratories over 1 kV) and
VDE 0105 have to be adhered to.
When measuring it is of utmost importance to pay special atten-
tion to proper grounding of the impulse voltmeter and the
ISOTEST holiday detector, i.e.
With the grounding (included in the delivery) a low-
impedance connection has to be established between one of
the black jacks of the impulse voltmeter and a grounding
point provided by the customer (protective earth conductor).
The
ISOTEST
®
holiday detector has to be grounded by the
grounding cable (also included in the delivery).
For this purpose the ISOTEST holiday detector has to be
connected to the second black grounding jack of the impulse
voltmeter by the cable with the black 6 mm connectors.
