Performance Check Procedure
f. Set bottom of the signal to bottom graticule line.
g. CHECK—the signal amplitude Is between 1.9 and 2.1 divisions.
h. Repeat the procedure for CH 2.
9.
CH 1 and CH 2 Vertical Deflection Accuracy
a. Set CH 2 VOLTS/DIV to 2 mV.
b. Set calibration generator to Std Ampl output, 10 mV.
c. Positlon the trace two graticule lines below the center horizontal
graticule line.
d.
