In order to avoid instrument damage, it is advi-
sed to remove accumulators when not using the
instrument over a certain period of time. Howe-
ver, should the instrument be contaminated by
leaking battery cells, you are kindly requested to
return it to the factory for cleaning and inspec-
tion.
Instruments must be stored in dry and closed areas.
In the case of an instrument being transported in ex-
treme temperatures, a recovery time of minimum 2
hours is required prior to instrument operation.
3.0 Safety Measures
The UNITEST TELARIS LOOP has been designed
and checked in accordance with the safety regulati-
ons for Electronic Test and Measurement Instru-
ments EN 61010 and IEC 1010, and left our factory
in a safe and perfect condition. To maintain this con-
dition the user must pay attention to the safety re-
ferences contained in this instruction manual.
The respective accident prevention regulations
established by the professional associations re-
garding electrical systems and equipment must
be strictly met for all tasks.
In order to avoid electrical shock, the valid sa-
fety and VDE regulations regarding excessive
contact voltages must receive the utmost atten-
tion, when working with voltages exceeding
120V (60V) DC or 50V (25V)rms AC. The values
in brackets are valid for limited ranges (eg for
medicine and agriculture).
Safety Measures
If the operator's safety can no longer be gua-
ranteed, the instrument is to be put out of ser-
vice and protected against use. The safety is no
longer guaranteed, if the instrument:
• shows obvious damage
• does not carry out the desired measurement.
• has been stored for too long under unfavou-
rable conditions.
• has been subjected to mechanical stress du-
ring transport.
The instrument may only be used within the
operating ranges as specified in the technical
data section.
Avoid any heating up of the instrument by direct
sunlight to ensure perfect functioning and long
instrument life.
The Earth Loop Resistance Measurement In-
strument complies with the overvoltage class
CAT III / 300V and may only be used for mains
systems of maximum 230 V (fused at maximum
16 A).
Only use the mains cable supplied. The unit
was calibrated with this cable and only in this
way can the resistance values measured be
exactly indicated.
