TCPA300 and TCPA400 Performance Verification
TCPA300 and TC
PA400 Performance Verification
This section
covers the performance verification for the TCPA300 and TCPA400
Current Probe Amplifiers. All of the procedures cover both amplifiers, exce pt the
Current Overload test, which is for the TCPA300 only. Power o n the amplifier and
test equipment and let them warm up for 20 minutes.
Before starting these procedures, photocopy the appropriate test record to record
the performance test results. The recommended calibration interval is one year.
(See page 17, TCPA300 Amplifier Test Record.)
Equipmen
tRequired
The performance verification procedures require the listed test equipment. The
test equipment must meet or exceed the specifications listed. You m ay need to
modify t
he test procedures if you do not use the recommended equipment.
