Free Chlorine
7.6.1.2
7.6.1.3
A detailed flow diagram is provided at the end of Sec. 7 to guide you through the calibration routines.
To calibrate free chlorine:
1. Press the MENU button
2. Select Calibrate. Press ENTER.
3. Select Sensor 1 or Sensor 2 corresponding to
Free Chlorine. Press ENTER.
4. Select Free Chlorine. Press ENTER.
The adjacent screen will appear. To calibrate Free
Chlorine or Temperature, scroll to the desired item and
press ENTER.
The following sub-sections show the initial display
screen that appears for each calibration routine. Use
the flow diagram for Chlorine calibration at the end
of Sec. 7 and the live screen prompts to complete cal-
ibration.
The adjacent screen appears after selecting Free
Chlorine calibration:

7.6.1.2 zeroing the sensor

The adjacent screen will appear during Zero Cal. Be
sure sensor has been running in zero solution for at
least two hours before starting zero step.
The adjacent screen will appear if In Zero Cal is
successful. The screen will return to the Amperometric
Cal Menu.
The adjacent screen may appear if In Zero Cal is unsuc-
cessful. The screen will return to the Amperometric Cal
Menu.

7.6.1.3 In Process Calibration

The adjacent screen will appear prior to In Process Cal
