WARNING
If excess current is input, generated heat activates a built-in
safety function that blocks normal output. If this happens,
remove the input immediately (unclamp 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.
WARNING
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.
WARNING
At high ambient temperatures, the built-in safety circuit may
activate at current input levels below the rated continuous
maximum.
WARNING
Continuous input of current exceeding the rated maximum or
repeated activation of the safety function may result in damage
to the unit.
WARNING
Do NOT measure current such that the total probe current
consumption exceeds the allowable AutoProbe interface current
consumption. The excess current consumption causes a
temporary shutdown of the Infiniium power supply for safety.
Quit the measurement and cycle the power of the Infiniium, if the
shutdown occurs. The typical probe current consumption from
the AutoProbe interface is shown in Figure 1 on page 9 .
