CALIBRATION PROCEDURE
NOTE
The oscilloscope and all test equipment must be
within calibration limits before an effective cali ­
bration can be performed on the Type 1A5.
Preliminary Procedure
1. Remove the side panels from the oscilloscope.
2. Move the oscilloscope plug-in sensing switch to its "out "
position. (Upper-right rear corner of plug-in compartment
of Type 544, 546 and 547 oscilloscopes only.)
3. Remove the Test Strap from the Input Amplifier board
and set it aside for future use. (Location is shown in Fig.
6-5).
4. Connect the rigid plug-in extender (item 7) to the Type
1A5 and the oscilloscope plug-in jack.
5. Set up the Type 1A5 and the Type 544 oscilloscope
according to Fig. 6-4 and the accompanying list of control
settings.
6. Energize the oscilloscope and all test equipment which
will be used in the calibration procedure. Adjust the Type
1A5 POSITION control as necessary to bring the oscilloscope
trace into the viewing area.
7. Allow 20 minutes warm-up before performing the cali ­
bration procedure.
