This instrument can measure the AC of commercial power.
It is also useful to make sure the subject conductor is not live
before measuring insulation resistance.
2.7 Voltage Measurement
• Test leads should only be connected to the secondary
side of a breaker, so the breaker can prevent an acci-
dent if a short circuit occurs. Connections should never
be made to the primary side of a breaker, because
unrestricted current flow could cause a serious acci-
dent if a short circuit occurs.
• The maximum input voltage and maximum rated volt-
age to earth is 600 Vrms (150 Vrms for the IR4030). If
their voltages are exceeded, this device will be dam-
aged and personal injury will result. Therefore, do not
perform measurement in this case.
• To avoid electrical shock, be careful to avoid shorting
live lines with the test leads.
Never press the MEASURE key while measuring voltage.
Doing so could damage the circuitry or cause a life-
threatening accident.
