(7) Adjust CH 2 VOLTS/DIV VAR control out of calibrated detent position.
Readout will be between 5.88 and 6.12 divisions. Return CH 2 VOLTS/DIV VAR control
to calibrated detent position.
(8) Repeat technique of (6) above for VOLTS/DIV switch settings listed in table 16.
Indications will be within limits specified in table 16.

(2) Press POWER pushbutton twice to activate self-test function. If horizontal
dashed line that appears is not within 1 minor division of the center horizontal graticule
line, adjust R345 STORATE VERTICAL CENTER (fig. 10) to align dashed line to the
center horizontal graticule line (R).
(3) Position controls as listed in (a) through (c) below:
(a) STORAGE MODE NORM pushbutton pressed.
(b) CURSOR FUNCTION VOLTS pushbutton pressed.
(c) VOLTS/DIV switch to 5m.
(4) Verify that bottom cursor is exactly 3 divisions below center horizontal graticule line.
(5) Press CURSOR SELECT pushbutton and adjust CURSOR control for LED
readout of 30.00 mV. Adjust R571 STORAGE VERTICAL GAIN (fig. 10) for 6 divisions
between VOLTS CURSORS (R).
