Figure 4.2.iv Probe Calibration
Once a fresh sample has been taken, press shown in Figure 4.2.iv, to enter a new
calibrated value taken from the manual sample, which the probe will now be calibrated to. This value
must be within 10% - 990% of the probe reading to avoid incorrect calibration. If there is an air lock,
the TDS probe will not be calibrated as the reading will be 0ppm.
When the probe calibration is completed, press and exit this screen.
