Calibration Check With DISPLAY OFFSET Selector
switch set to NORM (OFF), spot is
deflected 10 divisions both vert-
ically and horizontally within 1.5%
whenever the CAL button is pres-
sed.
With DISPLAY OFFSET Selector
switch set to X10 MAGNIFIER
(either axis) the calibration spot is
within 0.5% of zero spot (previous
ly set to CRT graticule center)
when CAL button is pressed.

Vertical and Horiz- Coarse positioning in 5 division in-
ontal Position Controls crements within 0.1 division; con-
tinuous fine positioning over at
least 5 divisions for each coarse pos-
ition.
Display Offset Vertical or Horizontal offset of dis-
play centerline value up to 10 divis-
ions in 21 half division steps.
Display Positioning Spot positioning with change in

Type
Electrostatic deflection.
Screen Size
Calibrated area of 10 divisions by
1 0 divisions; 12 usable divisions
horizontally ( 1 division equals 1
em).
Typical Accel- 4000V
lerating Po ten-
tial
Readouts Automatic digitally lighted display.
Readout is automatically blanked if
readings would be outside the avail-
able ranges or would give erroneous
display.
PER VERT DIV
1 nAto 20 A calculated from VER-
TICAL switch setting, DISPLAY
OFFSET Selector switch setting
and MODE switch setting (or X 10
Vertical Interface Input).
PER HORIZ DIV 5 mV to 200 V calculated from
HORIZONTAL switch setting and
DISPLAY OFFSET Selector switch
setting
PER STEPS
5 nA to 2A and 5 mV to 20 V cal-
culated from AMPLITUDE switch
setting and .1X STEP MULT but-
ton position (or X10 Step Interface
Input).
