Trouble Shooting
If any faults should occur please check the instrument according to the
procedure outlined below .
When a fault has been traced and corrected, the voltages and adjust-
ments influenced by the correction must be rechecked. The complete in-
strument should then be tested according to the Checking Procedure to
make sure that all basic functions are operative.
The
tolerances given in these notes are intended for use as guide for ad-
justments.
Before correcting any apparent deviation make sure that the measuring
instrument has tolerances small enough not to affect the measurement .
