(5) Rotate oscilloscope calibrator EDIT FIELD knob for 5 divisions of vertical
deflection on TI. If oscilloscope calibrator err display readout does not indicate within r2%,
perform b below.
Figure 3. Test instrument - bottom view.
(6) Repeat technique of (4) and (5) above for VOLTS/DIV switch settings listed in
table 3. Oscilloscope calibrator err display readout will indicate within specified
percent error.
(7) Set MODE switch to CH 2 and press TRIGGERING SOURCE CH 2
pushbutton in and CH 1 pushbutton out.
(8) Activate oscilloscope calibrator CHAN 2 output and repeat (4) through (6) above
for CH 2.
