HV Tester 25 kV
3 PREPARATION FOR USE
3.1 Operating requirements
The carrying handle of HV Tester 25 kV can be adjusted by exerting
gentle sideways pressure on the buttons on either side in the joint area.
WARNING: The clearance between the high-voltage unit and
grounded or live parts as stipulated in DIN VDE 0104 must
be complied with.
CAUTION: Warning notices reading
DANGER!
HIGH - VOLTAGE
When the equipment is set up in the field, it must be placed outside the
cable trench and protected against dirt and moisture.
The HV Tester should be set up inside the cordon at a distance of
approx. 3 m from the high-voltage, preferably at operating height.
3.2 Power supply
3.2.1 Internal rechargeable battery
The set has an integrated rechargeable battery. This supplies power
when the "Mains" key switch is actuated.
The mains and external battery, if connected, take precedence,
however, and cause the internal battery to be switched off.
If the voltage is to low, the colour of the LED [13] p. 11 changes from
green to red. The high voltage will then be switched off after
approximately 10 minutes.
