Semiconductor Checks; Adjustment After Repair - Tektronix 7B92A Maintenance Manual

Maintenance-7B92A
Cam Switch Lubrication
In most cases, factory lubrication should be adequate for
the life of the instrument. However, if the switch has
been disassembled for replacement of switch sub-parts,
a lubrication kit containing the necessary lubricating
materials and instructions is available through any
Tektronix Field Office. Order Tektronix Part 003-0342-
01. General Electric Versilubee silicone grease should
be applied sparingly so that the lubricant does not get on
the contacts. Refer to Fig. 4-1 for lubrication
instructions.

SEMICONDUCTOR CHECKS

Periodic checks of the semiconductors in this instrument
are not recommended. The best check of
semiconductor performance is actual operation in the
instrument.
More details on checking semiconductor operation are
given under Troubleshooting.

ADJUSTMENT AFTER REPAIR

After any electrical component has been replaced, the
adjustment of that particular circuit should be checked,
as well as the adjustment of other closely-related circuits.
The Performance Check and Adjustment procedure in
this manual provides a quick and convenient means of
checking instrument operation. In some cases, minor
troubles may be revealed or corrected by adjustment.
