•
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 this instrument.
•
The maximum continuous input range varies according to
the frequency of the current to be measured. See the
figures in Chapter 2, "Specifications"
• If the current that exceed the maximum continuous input
range 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
insulated target conductor to be 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 maximum
continuous input range.
• Continuous input of current exceeding the maximum
continuous input range or repeated activation of the safety
function may result in damage to this instrument.
