20. Remove the banana plug adapter from the DMM and connect the precision 50 Ω terminator
to the DMM, making sure that the banana plug side marked ’GROUND" is connected to the
LOW or COMMON input of the DMM.
21. After the DMM has stabilized, record the reading to 100 μV resolution as ’Measured Output
Voltage, mid range’ in the Test record.
22. Calculate the error by dividing the measured mid range output voltage recorded in step B-21
by the expected mid range output voltage recorded in step B-19. Subtract 1 from this ratio
and multiply by 100% to get the error in percent.
23. Record the calculated error to two decimal places (±0.xx %) as ’Gain Error, mid range’ in the
Test record.
24. Verify that the mid range gain error is less than ±1.0% This completes the Performance
Verification of the HFP1000. Complete and file the Test Record, as required to support your
internal calibration procedure.
Apply suitable calibration label to the HFP1000 housing as required.
