The TCP303 is a 150 A RMS probe with a peak current of 212 A. Apply current for
only a short amount of time.
5. Slowly increase the output of the current source until the OVERLOAD LED
on the amplifier is on.
CAUTION.
Do not leave the current turned up longer than necessary -- damage to
the equipment or personal injury may result.
6. Decrease the output of the current source to zero.
7. Record the results (pass/fail) on the test record.
8. Repeat steps 3 through 7 for the opposite polarity.
This completes the performance verification for the amplifiers.
If the TCPA300 or TCPA400 amplifier fails any of the verification tests, refer to
the
Adjustments
section for servicing information.
