TCP305 and TCP312 Performance Verification
TCP305 and TCP
312 Performance Verifi cation
The test proc
edures in this section verify warranted specifications and
proper performance of the TCP305 and TCP312 current probes, using the
TCPA300 Amplifier. Tolerances that are specified in these procedures apply to the
amplifier and current probe and do not include test equipment error.
Before starting these procedures, photocopy the appropriate test record to record
the performance test results. (See page 29, TCP305 Current Probe Test Record.)
The recommended calibration interval is one year.
NOTE. If the amplifier is not properly terminated into 50 Ω,theNOT
TERMINAT
ED INTO 50 Ω status LED is on. Verify that the 50 Ω termination is
connected at the D MM input when performing the following procedures.
No prob
eoramplifier adjustments are required during these test p rocedures. If
any tests fail, information is available. (See page 50, TCP305 and TCP312 DC
Gain Adjustment.)
WARNING. Magnetic fields are produced in these procedures that may cause a
malfunction in heart pacemakers or damage to sensitive equipment.
