PROCEDURE STEPS
1. Check Deflection Accuracy and Variable Range
a. Connect a 10-mV standard-amplitude signal to the
CH 1 OR X input connector using a 50-J2 cable.
b. CHECK—Deflection accuracy is within the limits
given in Table 4-2 for each CH 1 VOLTS/DIV switch set
ting and corresponding standard-amplitude signal. When
at the 20-mV VOLTS/DIV switch setting, rotate the
CH 1 VOLTS/DIV Variable control fully counterclockwise
and CHECK that the display decreases to 2 divisions or
less. Then return the VOLTS/DIV Variable control to
the CAL detent and continue with the 50-mV check.
c. Set the VERTICAL MODE switch to CH 2 and move
the cable from the CH 1 OR X input connector to the
CH 2 OR Y input connector.
