Trace Rotation
Adjustment
5-6
NOTE
Normally the trace will be parallel to the center horizontal
graticule line, and the TRACE ROT A TION adjustment will
not be required.
If you have to readjust the Trace Rotation, use the following
procedure:
Step
1.
Press the AUTO SETUP button and obtain a baseline
trace.
Step 2. Use the CH 1 POSITION control to move the baseline
trace to the center horizontal graticule line.
Step 3.
If the baseline trace is not parallel to the center
horizontal graticule line, the TRACE ROTATION
potentiometer needs adjusting.
The Trace Rotation potentiometer is located inside the instrument
and can be adjusted from the bottom side, as indicated on the
cabinet. You should use a small-bladed insulated screwdriver or
alignment tool to readjust the trace with the graticule line.
