These values can be changed by the user to have the analog
output matching 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.
The analog output is factory calibrated through software.
The user may also perform these calibration procedures
following the procedure at page 46. It is recommended to
perform the output calibration at least once a year.
