International Safety Symbols
This symbol, adjacent to another symbol or terminal, indicates the user must refer to the
manual for further information.
This symbol, adjacent to a terminal, indicates that, under normal use, hazardous voltages
may be present.
Danger: identifies conditions and actions that pose hazard(s) to the user.
Warning: alerts the user to avoid electric shock.
Caution: identifies conditions and actions that may damage the Insulation Resistance
tester.
Operating Caution: identifies conditions where the user needs to take extra care during the
operation of the Insulation resistance tester
Danger: Use of this instrument in a manner not specified by the manufacturer may impair
safety features/protection provided by the equipment. Read all of the safety information
carefully before using or servicing the instrument.
This symbol indicates that the meter uses double or reinforced insulation.
Safety Notes
Do not exceed the maximum allowable input range for any of the meter’s functions.
Set the function switch OFF when the meter is not in use.
Remove the batteries if the meter is to be stored for longer than 60 days.
Warnings
Set the function switch to the appropriate position before measuring.
Do not measure current on a circuit whose voltage exceeds 600V.
When changing ranges always disconnect the test leads from the circuit under test.
Do not use the Insulation resistance tester if it is damaged or if metal parts are exposed. Also,
check the meter for cracks or missing plastic.
Be careful when working above 30V AC rms or 30V DC. Such voltages pose a shock hazard.
Discharge all circuit loads under test after measuring high voltage.
Do not replace the batteries with the tester in a wet environment.
Place the test leads in the proper input terminals. Ensure that the test leads are firmly
connected to the Insulation Resistance tester’s input terminals.
Ensure that the Insulation Resistance tester is switched off when opening the battery
compartment.
