c. Set POWER switch to ON and allow at least 20 minutes for warm-up.
d. Adjust INTENSITY and FOCUS control for suitable viewing.

a. Performance Check
(1) Connect oscilloscope calibrator SOURCE/MEASURE CHAN 1 to TI CH 1
INPUT and CHAN 2 to TI CH 2 INPUT.
(2) Set oscilloscope calibrator for a CHAN 1, VOLTAGE mode output of 100 mV,
and frequency of 1 kHz.
(3) Rotate oscilloscope calibrator knob located below EDIT FIELD key for 5
divisions of vertical display. If oscilloscope calibrator Err display does not indicate within
limits specified in first row of table 3, perform b (1) and (2) below.
(4) Repeat technique of (2) and (3) above for TI and oscilloscope calibrator output
settings listed in table 3. Oscilloscope calibrator Err display will indicate within limits
specified in table 3.
