TCPA300 and TCPA400 Performance Verification
For example, u s
ing an expected output V
E
of 2.5000 V and a measured output M
1
of 2.510, the %Error would be:
NOTE. It is important that the correct polarity be used to calculate the % Error.
6. Verify that the measured DC g ain accuracy is within the limits specified for all
settings in the test record for the TCPA300. (See page 17, TCPA300 Amplifier
Test Record.) The TCPA400 test record is available. (See page 18, TCPA400
Test R ecord.) Record the %Error in the test record.
NOTE. If the %Error on any of the settings is greater than the specified limit, you
must perform the adjustment procedure. (See page 58, DC Gain Adjustment.)
7. Disconnect the DMM cable from the amplifier and the calibration adapter
from the current source.
