this is good advice,because without a service manual and cal procedure,you
have no way of knowing what adjustments INTERACT with others.
Adjust a power supply,and gain and timing goes out the window.
Freq.response tweaks can affect more than one area of the signal.

for example,
TEK 475s have multiple vertical gain adjustments,and different adjustments
for the 2/5-10mv ranges.And the gain affects F-response.

A *real* good example of calibration adjustments that interact is
the trigger delay lines used in 60's era scopes. Without a
program, calibrating one was impossible (hard enough with).
