8.2.1.1 Analog sensor
Select sensor type Analog and press [ENTER].
Available measurement types are (depends on transmitter type):
Measurement parameter Type
pH / ORP = pH or ORP 1,2,3
ISFET = pH measurement based on ISFET technology 1,2,3
Cond (2) = 2 electrode conductivity 1,2,3
Cond (4) = 4 electrode conductivity 1,2,3
Cond Ind = Inductive conductivity 1 Cond Ind
O
2
hi = Dissolved oxygen or oxygen in gas (ppm) 2,3
O
2
lo = Dissolved oxygen or oxygen in gas (ppb) 3
CO
2
= Accurate CO
2
measurement 3
The 4 lines of the display can now be configured with sensor channel ”A” for each line of the
display as well as measurements and unit multipliers. Pressing the [ENTER] key will display the
selection for lines a, b, c and d.
8.2.1.2 ISM sensor
Select sensor type ISM and press [ENTER].
If an ISM sensor is connected, the transmitter automatically (Parameter = Auto) recognizes
the type of sensor. You can also fix the transmitter to a certain measurement parameter (Param-
eter = pH / ORP, Cond(4), O
2
hi or 0
2
lo), depending on the type of trans mitter you have. Choose
the display setting for line a, b, c, d.
Measurement parameter Type
pH / ORP = pH and ORP 1, 1 Cond Ind, 2, 3
Cond (4) = 4 electrode conductivity 1, 1 Cond Ind, 2, 3
O
2
hi = Dissolved oxygen or oxygen in gas (ppm) 2, 3
O

Opt = Dissolved oxygen optical 2, 3
8.2.1.3 Save changes of the channel setup
After the procedure of the channel setup described in the previous chapter pressing the [ENTER]
key again will bring up the Save Changes dialog. Selecting No will discard the entered values
and return to the measurement display screen, selecting Yes will save changes made.
