When and how to change the battery inside the testing handle
Under standard operating conditions the battery inside the testing handle
of the ISOTEST
®
will last several years.
So
before
changing the battery please check if you can hear an acoustic
signal after switching the ISOTEST
®
on.
If this signal is missing not the battery in the handle but the main supply
accumulator
inside the device has to be loaded or changed.
In case you can hear an acoustic signal when you first switch on the main
switch but you do not hear one if you second press the safety test button
you have to change the battery in the handle.
To change the battery please proceed as described on the back page (
step 1 to step 6).
