6. After the DMM has stabilized, record the reading to 1 mV resolution on the Performance
Verification Test Record (on page 70 ) as Probe Output Voltage (step 5).
7. Take the probe's attenuation into account by multiplying the reading recorded 3 steps prior
(for Probe Input Voltage) 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.
8. On the Performance Verification Test Record (on page 70 ) , record the result as
Corrected Output Voltage (step 6).
9. Divide the Output Voltage (obtained 2 steps prior) by the Input Voltage (obtained 4 steps
prior). Subtract the ratio from 1.0 and multiply the result by 100% for the error percentage.
10. On the Performance Verification Test Record (on page 70 ) , record the result to two
decimal places (±0.xx %) as Probe Attenuation Error (step 7).
11. Ensure the calculated Probe Attenuation Error is less than ±2%.
