Iso-Tech IRT2310 Bedienungsanleitung Seite 3

This instrument must only be used on single-phase circuits with
a supply voltage of 230 Volts ac +10, -15% phase to neutral or
phase to earth. Do not connect the instrument between phases
on a 3-phase 415 Volts system.
When conducting tests, particularly if using earth spikes, do
not touch any exposed metalwork. Currents flowing during
the test may generate hazardous voltages in any earthed
metalwork.
Never open the instrument case. There are no user
replaceable parts inside.
This instrument is protected internally by HBC ceramic fuses.
Do not attempt to replace the internal fuses – they are not
user replaceable. If they fail, return the instrument to RS
Components for repair – the address is given at the end of
these instructions.
Examine the instrument and test leads before use for any sign
of abnormality, damage or contamination. If any abnormal
conditions exist (i.e. broken test leads, cracked insulation or
case, moisture contamination, display faults or inconsistent
readings etc.) do not use the instrument, but rectify the fault
first. Replace defective leads only with the correct types,
or return the instrument for repair. Contact RS Components
for further advice; the address is given at the end of these
instructions.
If the overheat symbol appears in the display, disconnect the
instrument from the supply and allow it to cool down.
When making connections to circuits, keep your fingers behind
the safety barriers on the test leads and crocodile clips.
Voltages above 50 Volts are considered hazardous as they
pose a shock hazard. Wear suitable Personal Protective
Equipment if working in the presence of un-insulated
conductors carrying voltages greater than 50 Volts.
Avoid working alone, so assistance may be summoned if
required.
If during testing there is a momentary degradation of readings
or abnormal results, this may be due to excessive transients
or discharges on adjacent circuits in the local area. If this is
suspected, repeat the test to verify the reading. If in doubt,
contact RS Components for further advice.
TEST EQUIPMENT RISK ASSESSMENT
Users of this equipment and/or their employers are reminded
that Health and Safety Legislation requires them to carry out a
valid risk assessments of all electrical work, so as to identify
potential sources of electrical danger and risk of electrical
injury such as from inadvertent short circuits. Where the
assessments show that the risk is significant then the use of
fused test leads constructed in accordance with HSE guidance
note GS38 "Electrical Test Equipment for use by Electricians"
should be used.
