Risk of instrument damage due to continuous input current
At high ambient temperatures, the built-in safety circuit may activate at
current input levels below the rated continuous maximum current.
Continuous input of current exceeding the rated maximum or repeated
activation of the safety function may result in damage to the device.
Current measurement exceeding approx. 1 kHz may result in tempera-
ture rise on the sensor-head. This is attributed to excitation loss that
cannot be prevented due to natural physical principles. Be careful to
avoid injury, electric shock due to short-circuits, or damage to the device
that may be caused by the increased temperature.
Do not place any unclamped conductor with an electric current of a fre-
quency of 10 kHz or more near the sensor head. Current flowing in the
conductor nearby may heat up the sensor head and cause its tempera-
ture to rise, leading to damage to the sensor. For example, when one
side of a go-and-return conductor is clamped and the other side is also
placed near the sensor head as shown in the diagram, even if the elec-
tric current is lower than the consecutive maximum current, electric cur-
rents in both sides will heat up the sensor and raise the temperature,
thereby causing damage to the sensor.
