3. Repeat this process for each sensor on the probe.

The expected air and water counts are dependent on the sensor type and sampling mode. Normalization

values outside the expected range may indicate errors in the normalization steps or problems with the

hardware.

Step 6 – Changing the Calibration Coefficients

To change the calibration coefficients of the sensors:

1. Click on the sensor coefficients cell when it is selected and it will go into edit mode as shown above.

2. Type the new coefficients separated by semicolons. To accept the new coefficients click outside the

cell or press Enter. If you want to discard the changes while in edit mode then press Escape. The

new coefficients will not be set in the probe’s configuration until you use the Write to Probe button.

The default calibration equation coefficients provided for different sensor types are listed in Table 3.

Step 7 – Addressing the Probe

Where there are multiple probes connected to a logger in a multi-drop situation, it is necessary to assign

each probe a unique address to avoid a clash in communication.
