1. SAFETY WARNINGS
1.1. International Safety Symbols
Warning of a potential danger, comply with instruction manual.
Caution! Dangerous voltage. Danger of electrical shock.
Double insulation.
1.2. Safety Notes
• Reference. Please use utmost attention.
• Do not exceed the maximum allowable input range of any function
• Insulated personnel body protective equipment up to 690V.
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 test
instrument are in perfect condition.
When using this instrument only the handles of the probes may be
touched – do not touch the probe tips.
This instrument may only be used within the ranges specified and
within low voltage systems up to 690V.
Prior to usage ensure perfect instrument function (e.g. on known
voltage source).
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.
The safety can no longer be insured if the instrument:
Ÿ Shows obvious damage
Ÿ Does not carry out the desired measurements
Ÿ Has been stored for too long under unfavorable conditions
Ÿ Has been subjected to mechanical stress during transport.
