Before starting the procedure, preset R16, R17, and R18
counterclockwise. Do not preset any other internal calibra­
tion controls unless they are known to be significantly out of
adjustment. In this case, set the remaining controls, with the
exception of R12 to midrange. Do not adjust R12, which is a
part of the temperature compensation network. This is set at
the factory according to
the requirements of the Hall device.
If the probe transformer is replaced, contact your local
field office for adjustment procedure. Fig. 6-3 shows the
location of internal adjustments.
