TCPA300/400 Amplifiers and TCP300/400 Series Current Probes Instruction Manual
5-1
Performance Verification Overview
The Performance Verification tests allow you to demonstrate that the Current
Probe Amplifier and Current P robes meet their specified levels of performance.
Since the TCPA300 and TCPA400 cannot operate without a current probe, a
calibration adapter is used to verify the amplifier(s) separately. The TCPA
Calibration Adapter is an optional accessory--see Replaceable Parts for part
numbers. After you have verified the amplifier performance independent of the
current probe(s), you can check the performance of current probes with
confidence.
Tolerances that are specified in these procedures apply to the amplifiers and
current probes and do not include test equipment error. The recommended
calibration interval is one year.
Performance Verification and Functional Checks
The warranted specifications for the amplifiers that are checked in the perfor-
mance verification procedures are listed in Table 5--1. See Table 4--1 in Specifi-
cations for warranted values. Functional checks are included for you to verify
proper amplifier operation.
