2 Testing Performance
The ∆Y value on the lower line of the display should be
within the test limits of Table 9. If a result is not
within the test limits, go to the “Troubleshooting”
chapter. Then return here.
6 Continue to check the voltage measurement accuracy with
the remaining Volts/div setting values in Table 9.
7 When you are finished checking all of the voltage values,
disconnect the oscilloscope calibrator from the
oscilloscope.
8 Repeat this procedure for the remaining channels to be
tested.

Use a Blocking Capacitor to Reduce Noise
On the more sensitive ranges, such as 2 mV/div and 5 mV/div, noise may be a factor. To
eliminate the noise, add a BNC Tee, blocking capacitor, and BNC shorting cap at the
oscilloscope channel input to shunt the noise to ground. See Figure 4.
