5.6 USING HOLD
during calibration, the sensor may be exposed to solutions having concentration outside the normal range of the process.
to prevent false alarms and undesired operation of chemical dosing pumps, place the transmitter in hold during calibra-
tion. Activating hold keeps the transmitter output at the last value or sends the output to a previously determined value.
See Section 7.3, output Ranging, for details.
After calibration, reinstall the sensor in the process stream. Wait until readings have stabilized before deactivating Hold.
to activate or deactivate Hold:
1. Press HoLd on the remote controller.
2. the
HoLd
prompt appears in the display. Press
é
or
