2 Safety and operational considerations
2.1 Warnings
Read and understand all warnings and cautions before using this product. This will
ensure your safety, as well as keep the test equipment undamaged.
q
symbol on the instrument means »Read the Instruction manual with
special care«. The symbol requires an action!
q
If the test equipment is used in a manner not specified in this user manual the
protection provided by the equipment may be impaired!
q
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!
q
Do not use the test equipment and accessories if any damage is noticed!
q
In case a fuse has blown follow the instructions in this manual to replace it!
q
Consider all generally known precautions in order to avoid risk of electric shock
while dealing with hazardous voltages!
q
Do not use the test equipment in supply systems with voltages higher than 240
V!
q
Do not disassemble, risk of electric shock – service intervention or adjustment
procedure is allowed to be carried out only by a competent authorized person!
q
Use only standard or optional test accessories supplied by your distributor!
q
Do not short-circuit any of the calibrator inputs/outputs!
Immediately disconnect from the power line and discontinue use if:
q
the calibrator is dropped or subjected to an impact in which the interior is
exposed,
q
the calibrator emits a strange smell, excessive heat, or smoke.
Function specific warnings (applies to all operations performed with Eurocheck):
q
In some countries the type of mains plug determines L and N wiring positions.
If Eurocheck signals incorrect polarity this represents an installation fault, which
should be corrected immediately.
q
When performing fault loop/trip-lock/line impedance calibration Eurocheck
always connects loop calibration output to mains line impedance (L and N), thus
avoiding tripping an RCD on mains supply. When evaluating absolute
measurement results line impedance of the mains has to be considered, not fault
loop impedance. Recommended calibration procedure, described in this
document, relies on the absolute result and the difference between two
measured values.
