(13) Set oscilloscope calibrator VOLTAGE output to settings as listed in 1st row in
table 4. Oscilloscope calibrator frequency will remain at 1 kHz for all settings in table 4.
(14) Set CH 2 VOLTS/DIV switch to VOLTS/DIV settings in 1st row of table 4 and
rotate oscilloscope calibrator knob located below EDIT FIELD pushbutton to obtain
oscilloscope display divisions as listed in 1st row of table 4. Oscilloscope calibrator err
display will indicate within limits specified in table 4; if not, perform b below.
(15) Repeat technique of (11) through (14) above for remaining rows listed in table 4.
Oscilloscope calibrator err display indications will be within limits specified in table 4.

(16) Deenergize oscilloscope and remove TI from left vertical compartment and
reinstall, using extender.
(17) Energize oscilloscope.
(18) Set CH 1 VOLTS/DIV switch to 5 mV and DISPLAY MODE switch to CH 1.
(19) Ensure oscilloscope calibrator CHAN 1 is connected to CH 1 using a 5-80 pF
standardizer. Press oscilloscope calibrator CHANNEL pushbutton and press blue soft
pushbutton located below CHAN 1.
(21) Adjust oscilloscope calibrator output for 6 divisions of display.
(22) Adjust standardizer for optimum square wave. If optimum square wave cannot
be obtained, adjust CHANNEL 1 C100 (CH 2 adjust C100 CHANNEL 2) (fig. 1 or 2) to
midrange and readjust standardizer for optimum square wave.
