The "Vertical-System Electrical Center" of the 5^0-oeries oscilloscope should,
be determined in the following manner:
Using a TEST LOAD UNIT, depress the PRESS TO SHORT INPUT button and
observe the vertical level of the trace. If you use a Type
$3/^1’
Plug-in unit, jumper between pins
1
and 3 on the
16
-pin connector
and observe the vertical level of the trace. This level will be
referred to later in the calibration procedure.
