The SMS-22 was evaluated and calibrated at the factory before shipment. Upon initial start up the
system should require minimal to no adjustments.
Verify the system has adequate flow, the pH electrode and the temperature sensors are reading
correctly. These parameters effect the measurement and must meet the standards listed in the
Calibration Section above. If these conditions are met and problems still exist use the Troubleshooting
Table to find a remedy.
