(10)Adjust CH 1 VARIABLE VOLTS/ DIV control fully ccw. TI display waveform
will not exceed 1.6 divisions in amplitude. TI display ∆V readout will be less than 8.0 V
and > sign will appear on TI display.
(11) Adjust CH 1 VARIABLE VOLTS DIV control fully cw.
(12) Press AQR MODE CH 2→2 pushbutton and repeat (3) through (10) above for CH 2.
(13) Remove all connections from TI.
b. Adjustments. No adjustments can be made.

a. Performance Check
(1) Press MENU/TEST, MEMOR DISPLAY 4, 5, 6 and MENU/TEST pushbuttons.
(2) Press f (function) and CURSOR ∆ON pushbuttons.
(3) Set CH 1 VOLTS/DIV switch to 20 mV.
(4) Set TIME/DIV switch to 200 s.
(5) Connect oscilloscope calibrator SOURCE/MEASURE CHAN 1 output TI CH 1
input and set oscilloscope calibrator frequency for 1 kHz and output amplitude to 50 mV.
(6) Adjust CURSORS 1 and 2 as shown in figure 7.
(7) Press AVE N pushbutton.
