Output Zero Voltage
9. Initiate an AutoZero.
10. Wait an additional 15 minutes, then record the DMM reading to 1 mV resolution on the
Performance Verification Test Record (on page 70 ) as Output Voltage after AutoZero
(step 2).
11. Take the difference of the two readings recorded steps 8 and 10 (previous) and multiply by
the Effective gain value shown in the channel attributes when the probe is attached. See
Operation with a Teledyne LeCroy Oscilloscope (on page 19 ) for more information.
12. On the Performance Verification Test Record (on page 70 ) , record the result as Output
Zero (step 3).
13. Verify the absolute value of Output Zero is less than 10 mV.
