SET UNIT SPs (11)
Evap Press Sensor
The pressure osets on menus 11 and 12 and the temperature
osets on menus 10, 11 and 12 correct the controller’s display
of the parameters. The sensors used in these units have a high
degree of repeatability but may need correction (oset). An
accurate pressure gauge or thermometer is used to determine
the correct temperature or pressure. A positive or negative
oset value is then entered to make the controller reading
agree with the measured value.

Two four-digit passwords provide OPERATOR and MANAGER
levels of access to changeable parameters. The passwords
are preprogrammed into the controller. Either password must
be entered using the ENTER PASSWORD (12) screen before
a protected setting can be changed. The operator password is
0100. The manager level is 2001.
