(17) Press VERTICAL MODE CH 2 pushbutton off and VERTICAL MODE CH 3
pushbutton on.
(18) Press CH 3 VOLTS/DIV pushbutton out to display .1 V on crt.
(19) Set oscilloscope calibrator for a CHAN 3, VOLTAGE mode output of 0.5 V at 1 kHz
frequency. If waveform displayed is not between 4.5 and 5.5 divisions, perform b below.
(20) Press CH 3 VOLTS/DIV pushbutton in to display .5 V on crt.
(21) Change oscilloscope calibrator output amplitude to 2 V. If waveform displayed is
not between 3.6 and 4.4 divisions, perform b below.
(22) Press VERTICAL MODE CH 3 pushbutton off and VERTICAL MODE CH 4
pushbutton on.
(23) Press CH 4 VOLTS/DIV pushbutton out to display .1 V on crt.
(24) Set oscilloscope calibrator for a CHAN 4, VOLTAGE mode output of 0.5 V at
1 kHz frequency. If waveform displayed is not between 4.5 and 5.5 divisions, perform b below.
(25) Press CH 4 VOLTS/DIV pushbutton in to display .5 V on crt.
(26) Change oscilloscope calibrator output amplitude to 2 V. If waveform displayed is
not between 3.6 and 4.4 divisions, perform b below.
(27) Press VERTICAL MODE CH 1 pushbutton on and VERTICAL MODE CH 2,
3, and 4 off.
(28) Set oscilloscope calibrator for a CHAN 1, VOLTAGE mode output of 10 mV
at 1 kHz frequency.
(29) Press ΔV pushbutton to indicate ΔV (cursors on).
(30) Set CH I VOLTS/DIV switch to 2 mV and adjust CH 1 VERTICAL
POSITION control to center waveform on display.
(31) Adjust ΔREF OR DLY POS control to align reference cursor with bottom of waveform.
(32) Adjust Δ control to align Δ cursor with top of waveform. If ΔV readout does not
indicate within limits specified in first row of table 5, perform b below.
