CAUTION
• The maximum continuous input range is based
on heat that is internally generated during
measurement. Never input current in excess of
this level. Exceeding the rated level may result in
damage to the probe.
• The maximum continuous input range varies
according to the frequency of the current being
measured. See the figures 3 on page 37 .
• If excess current is input, generated heat activates
a built-in safety function that blocks normal
output. If this happens, remove the input
immediately (remove the sensor from the
conductor being measured, or reduce the input
current to zero). Wait until the sensor has had
sufficient time to cool before resuming operation.
• Even if the input current does not exceed the
rated continuous maximum, continuous input for
an extended period of time may result in
activation of the safety circuit to prevent damage
resulting from heating of the sensor.
• At high ambient temperatures, the built-in safety
circuit may activate at current input levels below
the rated continuous maximum.
• Continuous input of current exceeding the rated
maximum or repeated safety circuit activation
will degrade performance of the safety circuit,
possibly resulting in damage to the device.
• The maximum input range is indicated by the
continuous maximum input range. It is also
indicated by another product specification
Maximum peak current: Noncontinuous 50 A
peak. This means that the upper limit of the
waveform response is 50 A peak. Make sure that
the input does not exceed the continuous
maximum input range in rms.
