To calibrate the sensor in buffer solutions, the sensor and a solution ground wire must be in the
container of the buffer solution. Perform the two-point calibration as follows:
Initialize the calibration.
Shut the isolation valves to the controller plumbing assembly.
Open the controller front panel. Disconnect the solution ground wire from terminal 5 of
terminal block P7.
Connect a wire that has been stripped at both ends to terminal 5 of terminal block P7.
Place the ORP sensor and the wire connected in the previous step into the lower value
buffer solution.

Re-install the sensor into the plumbing. Ensure locking ring is locked.
Remove the stripped wire from terminal block P7 and re-attach the solution ground wire.
Restore flow to plumbing assembly
Perform a single point calibration if necessary.

Calibration Check of ORP in Buffer solutions
To check the calibration of the sensor in buffer solutions, the sensor and a solution ground wire are
necessary. Perform the calibration check as follows:
Initialize the calibrations.
Shut the isolation valves to the controller plumbing assembly.
Open the controller front panel. Disconnect the solution ground wire from terminal 5 of
terminal block P7.
Connect a wire that has been stripped at both ends to terminal 5 of terminal block P7.
Place the ORP sensor and the wire connected in the previous step into the buffer
solutions.
Verify calibrations in at least two buffer solutions at least 2 pH apart.
Re-install the sensor into the plumbing. Ensure locking ring is locked.
Remove the stripped wire from terminal block P7 and re-attach the solution ground wire.
Restore flow to plumbing assembly
Perform a single point calibration if necessary
