User Guide

These values can be changed by the user to have the analog

output matches a different pH range, for example, 4 mA =

3.00 pH and 20 mA = 5.00 pH.

To change the default values, the setup mode must be en-

tered. Setup codes for changing the analog output minimum

and maximum are 41 or 42, respectively. For the exact

procedure, refer to the setup mode section in the manual.

Note The difference between maximum and minimum values for

the analog output must be at least 1.00 pH or 50 mV.

Note The analog output is factory calibrated through software. The

user may also perform these calibration procedures following

the procedure at page 36. It is recommended to perform the

output calibration at least once a year.
