DANGER
The maximum input voltage and maximum rated
voltage to earth are 150 Vrms (3452-11) and 500
Vrms (3452-12, 3452-13). Exceeding these limits
can damage the instrument or cause a serious
accident.
On the test probe there is a label stating
600 V,
however this is only the probe’s maximum rated
voltage, and is not the maximum rated voltage
of 3452.
Before connecting probes to the instrument,
check that the probes are disconnected from the
object to be measured.
Probe should only be connected to the
secondary side of a breaker, so the breaker can
prevent an accident if a short circuit occurs.
Connections should never be made to the
primary side of a breaker, because unrestricted
current flow could cause a serious accident if a
short circuit occurs.
