2.1 Warnings and notes
In order to reach high level of operator’s safety while carrying out various tests and
measurements using Smartec Insulation / Continuity test equipment, as well as to keep the
equipment undamaged, it is necessary to consider the following general warnings:
Warning on the instrument means »Read the Instruction manual with
special care to safety operation«. The symbol requires an action!
If the test equipment is used in a manner that is not specified in this user
manual, the protection provided by the equipment might be impaired!
Read this user manual carefully, otherwise use of the instrument may be
dangerous for the operator, for the instrument or for the equipment under
test!
Do not use the instrument and accessories if any damage is noticed!
In case a fuse has blown follow the instructions in this manual to replace it!
Consider all generally known precautions in order to avoid risk of electric
shock while dealing with hazardous voltages!
Service intervention or adjustment and calibration procedure is allowed to be
carried out only by a competent authorized person!
Use only standard or optional test accessories supplied by your distributor!
Consider that older and some of new optional test accessories compatible
with this instrument meet overvoltage category CAT III / 300 V! It means that
maximum allowed voltage between test terminals and ground is 300 V!
Instrument contains rechargeable NiCd or NiMh battery cells. The cells
should only be replaced with the same type as defined on the battery
placement label or in this manual. Do not use standard alkaline battery cells
while power supply adapter is connected, otherwise they may explode!
Hazardous voltages exist inside the instrument. Disconnect all test leads,
remove the power supply cable and switch off the instrument before
removing battery compartment cover.
All normal safety precautions have to be taken in order to avoid risk of
electric shock when working on electrical installations!
Warnings related to measurement functions:
Insulation resistance
Do not touch the test object during the measurement or before it is fully
discharged! Risk of electric shock!
Automatic discharge of capacitive object will take some time after the finished insulation
resistance measurement. Actual voltage is displayed during discharging until voltage drops
below 10 V. In no case you should disconnect test leads until tested object is completely
discharged!
