pH

pH Setup Checklist

1.  Make sure pH sensor type is selected.

(Refer to System Setup Menu, page 11)

2.  Set the Temperature Units (°C or °F).
3.  If LOOP is used, set the minimum and maximum 4 to 20 mA setpoints.
4.  Perform calibration (EasyCal, Standard or Standard and Slope).
5.  Set Last Cal Date and initials.
6.  Select source for Relay output (pH or Temp).
7.  If applicable, set up relay functions for your application.
