8.1.1
Enter cell constant
1. Press
CAL
and enter passcode: 1100,
ENTER
. CAL CELL will be
displayed for 3 seconds.
2. Use the
UP ARROW
and
RIGHT ARROW
to enter the value of the
cell constant of the connected sensor. The conductivity value will be
displayed also.
Note: For Hach or GLI contacting conductivity sensors, the cell
constant is usually printed on a tag with the sensor wiring.
Note: A cell constant change will change the conductivity value.
Note: If the entry of the cell constant takes longer than 6 seconds,
the display will alternate between showing the conductivity and the
temperature value.
3. Press
ENTER
to save the value.
4. The transmitter displays the cell constant value and CELL
.
Press
ENTER
.
5. The transmitter remains in HoLD mode. Press
ENTER
again.
The transmitter remains in HoLD mode for approximately
20 seconds after calibration and returns to the measure mode.
Note: Repeat entry of the cell constant when “Err” is displayed.
8.1.2
Calibration with a calibration solution
Note: Stabilize the temperature during calibration.
1. Press
CAL
, enter passcode: 0110,
ENTER
. CAL SOL will be
displayed for 3 seconds. The transmitter is ready for calibration.
2. Remove and clean the sensor.
3. Immerse the sensor in the calibration solution. Use the
UP ARROW
and
RIGHT ARROW
to enter the value of the calibration solution. If
temperature compensation is OFF, refer to
