2 Safety and operational considerations
2.1 Warnings and notes
In order to maintain the highest level of operator safety while carrying out various tests
and measurements Metrel recommends keeping your MicroOhm 10A instruments in
good condition and undamaged. When using the instrument, consider the following
general warnings:
The
symbol on the instrument means »Read the Instruction manual with
special care for safe operation«. The symbol requires an action!
If the test equipment is used in a manner not specified in this user manual,
the protection provided by the equipment could be impaired!
Read this user manual carefully, otherwise the use of the instrument may
be dangerous for the operator, the instrument or for the equipment under
test!
Do not use the instrument or any of the accessories if any damage is
noticed!
Consider all generally known precautions in order to avoid risk of electric
shock while dealing with hazardous voltages!
Do not use the instrument in supply systems with voltages higher than
300 V!
Service intervention or adjustment is only allowed to be carried out by
competent authorized personnel!
Use only standard or optional test accessories supplied by your distributor!
Consider that older accessories and some of the new optional test
accessories compatible with this instrument only meet CAT II / 300 V over
voltage safety rating! This means that maximal allowed voltage between
test terminals and ground is 300 V!
The instrument comes supplied with rechargeable Ni-Cd or Ni-MH battery
cells. The cells should only be replaced with the same type as defined on
the battery compartment label or as described in this manual. Do not use
standard alkaline battery cells while the 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
opening the battery compartment.
All normal safety precautions must be taken in order to avoid risk of electric
shock while working on electrical installations!
