Voltage Accuracy Verification - Keysight Technologies BT2152B Operating And Service Manual

Verification Step 4
Set the top-end current measurement range. (4.5 V
provides approximately 10 mA with the 442-ohm
resistor in place.)
Step 5. Wait 15 seconds for the BT2152A/B to settle before proceeding with measurements.
Step 6. Initiate a measurement. Send
flashes orange when this command is executed.
Verification Step 6
Set the time for the measurement in seconds
Set the interval the measurement in seconds
Step 7. While the BT2152A/B is performing its measurements, take a current reading with the DMM
and record this value.
Step 8. Wait for the measurement time set in step 6 to complete. Either send
the query returns a "1", or wait until the front panel TEST light turns off.
Step 9. Fetch the measurement reading from the BT2152A/B. Send
Verification Step 9
Return the measurement data from a channel
Step 10. Subtract the reference reading from the DMM obtained in step 7 from the reading from the
BT2152A/B measurement obtained in step 9. Verify if it within the specified accuracy provided in the
Quick Reference section of this guide.
Step 11. If verifying multiple channels, repeat steps 3 through 10 for the remainder of the channels in
the BT2152A/B.
Step 12. End the current verification. Send

Voltage Accuracy Verification

The voltage measurement accuracy is verified near or at the top and bottom of the scale. Offset error
dominates at the bottom of the scale while gain error becomes significant at the top of the scale.
Step 1. Leave the DMM connected to the verification fixture.
Step 2. Set the DMM for DC voltage measurement, 10 V range, and 10 PLCs (to integrate noise).
Step 3. Start the verification. Send
