16. Attenuation Compensation
a. Performance Check
(1) Connect oscilloscope calibrator SOURCE/MEASURE CHAN 1 output to TI
+INPUT, using termination.
(2) Set VOLTS/DIV switch to 50 mV and POSITION control to midrange.
(3) Press oscilloscope calibrator EDGE key and set oscilloscope calibrator output for
1 kHz and 5 divisions of vertical deflection on oscilloscope. If upper leading corner is not
square, adjust C241 (fig. 3) for optimum square wave (R).
(4) Remove connection from +INPUT and connect to -INPUT.
(5) Press -AC-GND-DC pushbutton to DC. If lower leading corner is not square,
adjust C141 (fig. 3) for optimum square wave (R).
(6) Set VOLTS/DIV switch to .1 V.
(7) Press +AC-GND-DC pushbutton to DC and -AC-GND-DC pushbutton to GND.
