CAUSE
REMEDY
Idle - no electrode contact with the test specimen
No or incorrect earthing connection
The earthing plug must be pushed
into the earthing socket up to the
stop. There must be no material
from the leather carrying case
between plug and socket.
Battery charge too low
ELMED ISOTEST testers are equipped
with exhaustive discharge protection
Replace battery or inspect old
battery and recharge.
During the test - with test electrode in contact with the test specimen
Excessive energy flow e.g. due to
moisture
Reduce the display sensitivity at
the adjustment knob until the
continuous signal stops. The
reduction in the display sensitivity
has no effect on the level of the set
voltage!!
Only for the ISOTEST 3P
If the safety button is pressed while the
main switch was being turned on
Turn off main switch
Switch on again without
pressing the safety switch.
If the safety button is pressed too hard.
Switch the unit off and on again.
Only press the safety buttom
after the first pressure point.
Continuous high-voltage flash-over
lasting more than 5 s.
Switch the unit off and on again.
Avoid continuous flash-overs.
In other cases, a "continuous buzzer" is the signal for a detected flaw in the test
