†For size 038, enter “034” for SIZE.
For size 048, enter “044” for SIZE.
For unit size 078, enter “074” for SIZE.

NOTES:
1. Calibration of the pressure transducers is not required unless prob-
lems with the transducers occur or the standard PSIO is replaced. To
calibrate pressure transducers:
a. Disconnect from system.
b. Hang in the atmosphere.
c. Read pressure. Pressures before calibration must be in the
range of ±3 psig (atmosphere).
d. Press
.
e. Reattach to system.
2. Upon completion of the factory/field configuration step, move to the
DTRS (Data Reset) subfunction. Press
, and all revised
inputs will be loaded. This procedure takes approximately 40 sec-
onds. The display returns to the default rotating display.
