6.4 Hold
6.4.1 Purpose
To prevent unwanted alarms and improper operation of control systems or dosing pumps,
place the alarm relays and outputs assigned to the sensor in hold before removing the
sensor for maintenance.
Hold is also useful if calibration, for example, buffering a pH sensor, will cause an out of
limits condition. During hold, outputs assigned to the sensor remain at the last value, and
alarms assigned to the sensor remain in their present state.
6.4.2 Using the Hold function
The Hold function uses certain programming features not discussed in Section 6.3.
Procedure
