Performance Verification
Performance Verification Overview
The Performance Verification tests allow you to demonstrate that the Current
Probe Amplifier and Current Probes 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 Replac eab le Part s for part
numbers. After you have verified the amplifier performance independent of the
current probe(s), you ca n check the performance of current pro bes with confidence.
Tolerances that are s pecified in these p rocedures apply to the ampl ifiers 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 performance
verification pro cedure s are lis ted in Table 5-1. See Table 4-1 in Specifications for
warranted values. Functional checks are included for you to verify prope r amplifier
operation.

Test Procedure Conditions
These procedures are valid only under the following conditions:
The system has been calibrated at an ambient temperature of 23°±5 °C.
The system is operating in an environment whose limit s are described in Table
4-6 on page 4-5.
The system, including probe, has had a warm-up period of at least 20minutes.
The probe degauss/autobala nce routine has bee n performed after the 20-minute
warm-up period.
Equipment Preparation
Before performing the verification tests, turn all equipment on and allow the entire
system to warm up for a minimum of 20 minutes.
NOTE. Before performing any ve rificat ion proced ure, prope rly degaus s the probe.
Remove the probe from a ny current -carryi ng conductor , lock the probe, and pr ess
the amplifier PROBE DEGAUSS AUTOBALANCE button. The
degauss/autobalance routine is complete when the indicator light turns green.
The amplifier front panel will light the NOT TERMINATED INTO 50 Ω LED
during the degauss/ au tobalance routin e if the amplifie r is not properly te rminated
into 50 Ω. Verify that the oscilloscope input i s 50 Ω and set to DC cou pling. Use a
50 Ω feedthrough termination, attached at the oscilloscope input, if necessary.

TCPA300 and TCPA400 Performance Verification
This section covers the perfor manc e ver if ica ti on for the TCPA300 and TCPA400
Current Probe Amplifiers. Refer to the list of equipm ent required in Table 5-3.
Power on the amplifier and test equipment and let them warm up for 20 minutes.
Before starting thes e procedures, photocopy the appropriate test record beginning
on page 5-16 to record the performance test results. The re commended cali bration
interval is one year.
Equipment Required
The performance verification procedures require the test equipment listed in
Table 5-3. The test equipment must meet or exceed the specifications listed. You
may need to modify the test procedures if you do not use the recommended
equipment.

Making DC Current Loops
You need to construct simple current loops to complete some tests for the
amplifiers. The current loops are also used in the DC gain accuracy tests for the
probes.
5-Turn DC Current Loop Construct the loop usin g a cylindrical form approximately 3 inches in diameter:
1. Wind exactly 5 turns of #18 coated wire around the form.
2. Scrape about a half-inch of coating off of the ends of the wire.
NOTE. Ensure that the current loop has exactly 5 turns. A significant error will
result for each turn variance from 5 turns.
The 5-turn DC current loop is also used in the current probe performance
verification and adjustment procedures.
50-Turn DC Current Loop Construct the loop using a cylindrical form approximately 3 inches in diameter:
3. Wind exactly 50 turns of #13 coated wire around the form.
4. Scrape about a half-inch of coating off of the ends of the wire.
NOTE. Ensure that the current loop has exactly 50turns. A significant error will
result for each turn variance from 50 turns.
The 50-turn DC current loop is also used in the current probe performance
verification procedures.
