Pt-2? [01/Jan/12]
Calibration point 1 (Pt-1) is the Zero NTU point. Calibration point 2
(Pt-2) is the 1000 NTU point.
The dates shown to the right of each point are the dates of the last
successful calibration.

The Meter will wait until the readings are stable, then it will send
the calibration command to the Probe, where the calibration takes

The Calibration Report on the top line displays the voltage output
from the Turbidity Receiver Electrode in millivolts (mV). This value
is not stored in memory so should be noted down in a calibration
