(15) Reduce all outputs to minimum.
(16) Set CH 2 VOLTS/DIV switch to 2 mV.
(17) Press CH 2 input coupling pushbutton to select 50 : DC.
(18) Set oscilloscope calibrator for a CHAN 2, VOLTAGE mode output of 10 mV at 1
kHz frequency and SCOPE Z of 50 Ÿ.
(19) Rotate oscilloscope calibrator knob below EDIT FIELD pushbutton to adjust
amplitude for 5 divisions of deflection on TI. If oscilloscope calibrator err display does not
indicate within limits specified in first row of table 5, perform b below.
(20) Repeat technique of (16), (18) and (19) above for settings listed in table 5. If
oscilloscope calibrator err display does not indicate within limits specified in table 5,
perform b below.
