• Do not supply current that exceeds the maximum
continuous input range.
The values are derived from the rise in temperature caused when
the unit heats up during measurement. Do not input the current
that exceeds this. This instrument might be damaged. Moreover,
the maximum input range differs depending on the frequency of
the current being measured. See Figure 1.5.1 "Instrument
Specifications".
• When current exceeding the maximum continuous input
range is supplied, the sensor unit will heat up, triggering
an internal protective interlock that will prevent normal
output.
If this happens, cut off the input immediately (either by removing
the sensor from the insulating target conductor to be measured or
by setting the input current to zero). Then wait for a sufficient
amount of time for the unit to cool before resuming normal
operation.
• At high temperatures, the overcurrent protection circuit
in the unit may cause the protective interlock to operate
at
current
continuous input range.
• Do not subject the instrument to sudden rapid changes
in temperature, mechanical stress or shocks.
This may damage the instrument and the sensor head and result
in equipment failure.
• Keep the sensor head closed unless you are clamping
the insulating target conductor to be measured in
preparation for measurement.
Leaving the sensor head open may damage the sensor head.
