CALIBRATION PROCEDURE
General
In the following calibration procedure, a test equipment
setup is shown for each maior setup change. Complete
control settings are listed following the first equipment setup.
In subsequent setups, only the controls which have been
changed from the preceding step are listed. Controls which
are not shown on the setup list may be left in any position.
If only a partial calibration is performed, start with the near
est setup preceding the desired portion.
NOTE
When performing a complete recalibration, best
performance w ill be provided if each adjustment
is made to the exact setting, even if the Check is
within the allowable tolerance.
The following procedure uses the equipment listed under
Recommended Equipment. If substitute equipment is used,
control settings or setup must be altered to meet the require
ments of the equipment used.
Preliminary Procedure
1. Remove the side covers from the Type 503.
2. Connect the Type 503 to the autotransformer, and set
the autotransformer to 117 volts.
3. Turn the POWER AND SCALE ILLUM. control clock
wise and adjust the graticule illumination as desired.
4. Allow the Type 503 to warm up for at least 5 minutes
before proceeding further.
