1. Safety
1.3 Warnings
In order to avoid electrical shock, the valid safety and VDE regulations
regarding excessive contact voltages must receive utmost attention,
when working with voltages exceeding 120V (60V) DC or
50V (25V) rms AC. The values in brackets are valid for limited ranges
(as for example medicine and agriculture).
Prior to measurement ensure that the test leads and the lest instrument
are in perfect condition.
When using this instrument only the handles of the probes may be
touched - do not touch the probe lips.
This instrument may only be used within the ranges specified and
within low voltage systems up to 1 000V.
Prior to usage ensure perfect instrument function (e.g. on
known voltage source).
The voltage detector is not to be used if the battery box is open.
The voltage detectors have to be kept dry and clean.
The voltage testers may no longer be used if one or several
functions fail or if no functionality is indicated.
Do not use this instrument under damp conditions.
Perfect display is only guaranteed within a temperature range of
-10°C up to +55°C, at relative humidity question <85%.
If the operator's safety cannot be guaranteed, the instrument must
be removed from service and protected against use.
