Adjustment Procedure
3. Verify that th
e calibrator is in direct mode by pushing the
lower-bezel
button until 1.0 is selected.
4. Set the calib
rator amplitude as follows:
a. Select the Amplitude field using the front-panel tab key
.
b. Set the voltage specified by the oscilloscope prompt.
5. Push the ON button and verify that the red light turns on to indicate that
the calibrator output is on.
6. On the oscilloscope, push the OK Do Next Step right-bezel button.
