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 lubrica-
tion kit containing the necessary lubricating
materials and
instructions is available
through any Tektronix Field Office .
Order Tektronix Part
003-0342-01 . General Electric Versi-
lube © silicone grease should be applied sparingly so that
the lubricant does not get on the contacts . Refer to Figure
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 ad-
justment 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 .
