SET FUNCTION Mode
(alarm, control or status)
The analyzer is equipped with two electromechanical relays
(A and B). Each relay can be set to function as a
CONTROL, ALARM or STATUS relay. For details on each
relay function, see subsection “SET FUNCTION Mode.”
During calibration, CONTROL and ALARM relays can be
held, transferred to preset on/off states, or remain active.
During normal measurement operation, CONTROL and
ALARM relays can be held in their present on/off states for
up to 30 minutes by using the “HOLD OUTPUTS” function
in the TEST/MAINT menu.
These instructions configure Relay A. Configure Relay
B in the same way using its respective menu screens.
Each CONTROL or ALARM relay can be assigned to use
the measured pH or temperature for its operation.
