MODEL XMT-C SECTION 8.0

CALIBRATION — CONDUCTIVITY

8.1 ENTERING THE CELL CONSTANT

The cell constant should be entered:

• When the unit is installed for the first time

• When the probe is replaced

• During troubleshooting

All cell constants can be located on the cable label of the conductivity probe.

1. Press MENU. The main menu appears. Choose Calibrate. Press

ENTER.

2. Choose Conductivity. The screen at the left will appear. Press

ENTER.

3. Scroll right with the right arrow key. The screen at the left will appear.

4. Choose Enter Cell Constant. The screen at the left will appear.

5. Enter the actual cell constant as printed on the sensor tag attached to

the sensor cable.

NOTE

For sensors that show a "cal constant" on the label, the

actual cell constant can be calculated by adding 500 to

the cal constant, multiply this value by the nominal cell

constant, then divide the result by 1000.

6. Press ENTER. All conductivity readings will reference this sensor-spe-

cific cell constant.

7. Press EXIT once.

NOTE

The cell constant you have entered is changed after the

Standardizing Conductivity procedure is performed. For

inductive sensors and contacting sensors that only

show nominal cell constants, do not change it back to

the value as shown on the probe label.

If there is no cell constant on the label, calculate it

from the equation:
