Insulation Tester
1
⚫ Read all safety information carefully before attempting to operate or service the
meter.
⚫ Do not use the Tester around explosive gas, vapor, or in damp or wet environments.
⚫ Keep fingers behind the finger guards on the probes.
⚫ The circuit under test must be de-energized and isolated before connections are
made except for voltage measurement.
⚫ Circuit connections must not be touched during a test.
⚫ After insulation test, capacitive circuits must be allowed to discharge before
disconnecting the test leads.
⚫ To avoid damage to the instrument, do not apply signals which exceed the maximum
limits shown in the technical specification tables.
⚫ Do not use the meter or test leads if they look damaged. Use extreme caution when
working around bare conductors or bus bars.
⚫ Use the meter only as specified in this manual; otherwise, the protection provided by
the meter may be impaired.
⚫ Caution when working with voltages above 30 Vac rms, 42 Vac peak, or 60 Vdc.
Such voltages pose a shock hazard.
⚫ Before taking resistance measurements or testing continuity, disconnect the main
power supply and all loads from the circuit.
⚫ Remove all probes, test leads, and accessories before the battery door is opened.
⚫
Replace the batteries when the low battery indicator shows to prevent incorrect
measurements. False readings can lead to electric shock and injury.
⚫
Replace all batteries with fresh batteries of the same manufacturer and type to
prevent battery leakage.
⚫ Remove the batteries if the Tester is not used for an extended period of time, or if
stored in temperatures above 50
°
C. If the batteries are not removed, battery
leakage may result.
CAUTION!
⚫
Disconnect the test leads from the test points before changing the position of
the function rotary switch
.
⚫ Never connect a source of voltage with the function rotary switch in
Ω, LoΩ,
50V, 100V, 250V, 500V, 1000V position.
Environment conditions:
⚫ Installation categories CAT IV 600 V
⚫ Pollution degree 2
⚫ Altitude up to 2000 meters
⚫ Indoors use only
1.
