Section 6 —DM 5010
ADJUSTMENT PROCEDURE
Introduction
This procedure should be performed if the instrument
fails to meet the performance requirements of the electrical
characteristics listed in the Specification section of this man­
ual. To ensure continued instrument accuracy, adjustment
should be performed every 1000 hours of operation or every
six months if used infrequently. Adjustment is also recom­
mended following instrument repair or modification. Adjust­
ments must be made at an ambient temperature between
+ 21 °C to + 25’C. Allow thirty minutes warm-up time be­
fore beginning adjustments (sixty minutes after exposure to
or storage in high humidity environment).
The recommended interval for battery replacement is ap­
proximately every two years. Performance of the Adjust­
ment Procedure is necessary after battery replacement to
restore the calibration factors to memory. See the Mainte­
nance section of this manual for battery replacement
information.
Services Available
Tektronix, Inc. provides complete instrument repair and
adjustment at local field service centers and at the factory
service center. Contact your local Tektronix Field Office or
