Figure 1. Oscilloscope - right view.
(5) Repeat (4) above at autotransformer settings of 105 and 125 V err readout
indication will remain within 1 percent.
(6) Adjust autotransformer to 115 V.
b. Adjustments. No adjustments can be made.
9. Magnifier and Horizontal Gain
a. Performance Check
(1) Set HORIZONTAL DISPLAY control to EXT CAL and HORIZONTAL
MAGNIFIER switch to X1.
(3) Set oscilloscope calibrator for a 10 V output at 1 kHz. Rotate oscilloscope
calibrator knob located below EDIT FIELD button to adjust for 10 divisions of horizontal
deflection on TI. If oscilloscope calibrator err readout does not indicate within 5 percent,
perform b (1) and (2) below.
(4) Set oscilloscope calibrator for a 2 V output. Set HORIZONTAL MAGNIFIER
switch to X5. Rotate oscilloscope calibrator knob located below EDIT FIELD button to
adjust for 10 divisions of horizontal deflection on TI. If oscilloscope calibrator err readout
does not indicate within 5 percent, perform b (3) and (4) below.
