Calibrate Sensor A
Note. The Factory Calibration matches the specific linearity characteristics of the sensor
to the transmitter.
Sensor B calibration (dual input monitors only) is identical to Sensor A
calibration.
Single input monitors only – continued on page 46.
Operating Page – see Section 2.3.
Zero Calibration
Fill the flowcell with de-ionized water.
Press the key to initiate calibration.

Reference signal
As calibration proceeds, a progress indicator appears in the lower display line. After 3
minutes, the lower display line shows
100%, the display then advances
automatically to the next step.
Calibrate with Solution 1
Fill the flowcell with a 5mgl
–1
(7320 100 sensor) or 25mgl
–1
(7320 200 sensor) span
standard solution prepared from the stock standard solution – see Section 4.1.2.
