If the level is within a normal operating
The calculated value for the loop output is range, adjust the loop parameters to allow
LOOP > 20 mA greater than 20 mA. The loop output will be in proper tracking of the level. If the level is out of
its fail-safe mode. the normal 4–20 mA range, then correct the
problem with the level.
If the level is within a normal operating
The calculated value for the loop output is less range, adjust the loop parameters to allow
LOOP < 4 mA than 4 mA. The loop output will be in its proper tracking of the level. If the level is out of
fail-safe mode. the normal 4–20 mA range, then correct the
problem with the level.

darken the display or counterclockwise to lighten
the display until the desired contrast is obtained.
