output matching a different EC or TDS range, for example,

4 mA = 30 mS and 20 mA = 50 mS.

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 pro-

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

Note The analog output is factory calibrated through software. The

user may also perform the calibration procedure as explained

in the following. It is recommended to perform the output

calibration at least once a year.

Note Analog output resolution is 1.5‰ f.s. with 0.5% f.s. accu-

racy.

Note The analog output is “frozen” when entering the setup or

calibration mode (after password confirmation).
