• The respective accident prevention regulations
established by the professional associations for
electrical system and equipment must be strictly
met at all times.
• In order to avoid electrical shock, the valid safety
regarding excessive contact voltages must receive
utmost attention, when working with voltages
exceeding 120V (60V) DC or 50V (25V) rms AC. The
values in bracket are valid for limited ranges (as
for example medicine and agriculture).
• Never connect the tester to voltage for longer
than 30 seconds. For next operation, a recovery
time of minimum 240 seconds is needed
• The instrument may only be used within the
operating ranges as specified in the technical data
section and in low voltage system up to 600V.
• Measurements in dangerous proximity of electrical
system are only to be carried out in compliance
with the instructions of a responsible electronics
technician, and never alone.
• The electrical 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 5°C up to +40°C at relative
humidity <80%.
• Test leads and test probes may only be touched
at handle surfaces provided. Absolutely avoid the
direct contact of the rest probes.
• Prior to usage ensure perfect instrument function
(e.g. on known voltage source).
• The instrument may only be opened by an
authorized service technician.
