12. Calculate the gain error by taking 100 * [(Measured Output Voltage) –
(Expected Output Voltage)] / (Expected Output Voltage). Record this
value as the % Gain Error. Verify that this is within the limits given on
the data sheet.
13. Connect the signal generator to the DMM input and set the output
amplitude of the signal generator to 500 mVrms ±1 mV as measured on
the DMM.
14. Record the output voltage to 1 mV resolution as "Generator Output
Voltage, low range" in the Test Record. Be careful not to alter the output
amplitude after the reading is recorded.
15. Set the vertical scale of C1 to 200 mV/. Select the probe dialog tab and
record the value listed for ‘Effective Gain, low range’ on the test record.
16. Take the recorded generator output voltage and divide by the effective
gain. Record this value as ‘Expected Output Voltage, low range’ on the
test record.
a. Connect the banana plugs of the precision 50Ω adapter to the
input of the DMM. Measure the output voltage and record this
as ‘Measured Output Voltage, low range’ on the test record.
b. Calculate the gain error by taking 100 * [(Measured Output
Voltage) – (Expected Output Voltage)] / (Expected Output
Voltage). Record this value as the % Gain Error. Verify that this
is within the limits given on the data sheet.
This completes the Performance Verification of the ZD Series. Complete and file
the Test Record, as required to support your internal calibration procedure.
Apply suitable calibration label to the ZD Series housing as required.
