7. Equipment Setup
HIGH VOLTAGE is used or exposed during the performance of
this calibration.
DEATH ON CONTACT may result if
personnel fail to observe safety precautions.
REDUCE
OUPUT(S) to minimum after each step within the performance
check where applicable.
a. Remove TI protective cover only when necessary to perform adjustments.
b. Position controls as listed in (1) through (9) below:
(1) Both VOLTS/DIV switches to .1 and VARIABLE controls to CAL.
(2) CH1-CH2 mode switch to CH1.
(3) Both AC-GND-DC switches to AC.
(4) Both vertical POSITION controls to mid-range.
(5) Push in INVERT PULL (CH2 only) switch.
(6) Push in X10 GAIN AC (CH2 only) switch.
(7) TIME/DIV switch to 1 mSEC and VARIABLE control to CAL.
(8) Push in X10 MAG switch.
(9) TRIGGERING controls as listed in (a) through (c) below:
(a) SOURCE switch to CH1 & 2.
(b) COUPLING switch to AC.
(c) SLOPE switch to up position.
c. Connect TI to appropriate power source.
d. Pull POWER switch to ON and allow at least 20 minutes for warm-up.
8. Vertical Sensitivity and Stability
a. Performance Check
(1) Connect oscilloscope calibrator SOURCE/MEASURE CHAN 1 output to TI CH
input connector.
(2) Set oscilloscope calibrator to a VOLTAGE output of 400 mV and frequency
of 1 kHz.
(3) Adjust oscilloscope calibrator knob located below the EDIT FIELD key for 4
divisions displayed on TI crt. If Err displayed on oscilloscope calibrator is not within limits
shown in the first row of table 3 , perform b (1) and (2) below.
