12-4. Supplement of parameter setting

12-4-1. Set cell constant (service code 03)

Code 3 *0.10xC First select a multiplying factor, and then set the constant in consideration of this fac-
tor. The position of the decimal point can be selected after the first digit has been set
(when the decimal point is flashing).
*How to enter the cell constant
(1) In the case that the only cell constant is mentioned on the text plate of the sensor (SC211G,
SC8SG, SC4AJ). How to enter the cell constant of 0.0195 /cm: Select *0.01xC on the message
display, and then enter the value of 1.950 on the main display.
(2) In the case that the deviation of a nominal cell constant (± X.X%) is mentioned on the text plate
of the sensor (SC210G).
When the nominal cell constant is 5 /cm and the deviation (CORR.% = -1.1) is mentioned:
The cell constant to be entered is calculated as follows:
5 + 5 x (-1.1/100) = 4.945
How to enter the cell constant of 4.945 /cm:
Select *10.0xC on the message display, and then enter the value of 0.495 (rounded to three
decimal places) on the main display. (The first digit in the constant setting only accepts 1 or 2.)

12-4-2. Temperature sensor (service code 10)

Code 10 *T.SENS Selection of the temperature compensation sensor. The default selection is the
PT1000 sensor, which gives excellent precision with the two wire connections used.
The other options give the flexibility to use a very wide range of other conductivity/
resistivity sensors. The temperature sensors for the applicable conductivity sensors
are as follows. According to the conductivity sensor used, select the appropriate
temperature sensor.

12-4-3. Automatic return (service code 50)

If no key is operated for 10 minutes in any mode other than measurement mode or after 10 minutes in
Hold status, Auto-Return (factory setting: On (1) in service code 50) will be activated to return the trans-
mitter to measurement mode. To disable Auto-Return, set the service code 50 to Off (0).
WARNING
When stopping auto-return function, the transmitter doesn't automatically return to measurement mode. Take
care of returning measurement mode for re-measurement.
