Safety Guide
To avoid damage to the probe and inaccurate readings, do not use a current probe on a circuit that
exceeds the probe's maximum rated frequency or the maximum rated current at the measurement
frequency.
All current probes have a maximum current rating which may be derated depending on the
measurement frequency in accordance with the following table:
Probe
Probe maximum current by frequency
60 A pk max DC to 5 kHz,
TA018
derated to 15 A to 20 kHz
TA019
600 A pk max, DC to 400 Hz
2000 A pk max, DC to 200 Hz, derated to
TA167
200 A to 2 kHz, 20 A to 20 kHz
TA189
30 A pk max, DC to 100 kHz
TA234
30 A pk max, DC to 20 kHz
2000 A pk max, DC to 200 Hz, derated to
TA388
200 A to 2 kHz, 20 A to 20 kHz
TA408
100 A pk max, DC to 10 kHz
TA473
60 A pk max, DC to 50 kHz
TA496
60 A pk max, DC to 40 kHz
To prevent damage, always use and store your unit in appropriate environments as below.
