Changing the pH input from glass electrode to IsFET
sensor
With this device you can run the electrode types glass electrode / redox electrode or
IsFET sensors.
For adapt the electrical connection from glass electrodes to IsFET sensor CPS 401,
please proceed as follows:
1.
Open housing cover of the CPM 153.
2.
Pull off both ends of the red line to the pH input (s. Fig. 29, p. 105; line to
position 130).
3.
Pin up the jumper on the back sides of the included terminals "DRN" and "SRC".
4.
Remove the "pH" terminal out of the transmitter and replace it by the terminals
"DRN" and "SRC".
5.
Change the setting "electrode type" in the Quick Setup menu (p. 27) to "IsFET".
!
Note!
Please switch from IsFET sensor to glass electrode correspondingly.
