Additional consideration needs to be given to the amp second rating of the
transformer. The product of the pulse current and the pulse duration should be
less than the amp second rating to keep the transformer core from saturating.
When saturation occurs, the output voltage falls to zero.
Probe Handling
Only normal handling considerations are necessary with the CT-1 and CT-2
transformers. They are sealed units and are not designed to be disassembled. If
the transformer or cable is damaged, return it to Tektronix for replacement.
CAUTION. Dropping the CT-1 or CT-2 transformer may break the probe. Do not
pull or stretch the P6041 cable or place objects on the cable. This may damage
the probe cable.
