8.3 Calibration
As each sensor has its unique characteristics, the transmitter is not calibrated to a sensor
by default (Cal. Point: No Cal). Calibration procedure must be performed by trained
personnel each time a new sensor is connected.
•
This instrument provides multi-point standard buffer solution (Known Sol.)
calibration allowing users to decide the number of points to calibrate to (max. 5 points).
•
When calibrating, users can select the following electrodes in setup mode for
calibration: Turbidity TC-100, TC-500, TC-3000, or Suspended Solids TCS-1000.
•
During calibration, the displayed information will be slightly different based on the
sensor selected in setup mode.
•
During calibration, exceeding 80% of the sensor manufacturer’s suggested range is
not recommended .
•
For single point calibration, the reference value cannot be 0.
•
TCS-1000 electrode uses suspended solids (SS) standard solution, but is not easily
acquired. The transmitter is able to use turbidity standard solution to calibrate and
adjust the suspended solids measurement via a correction factor.
8.3.1 Known Solution Calibration
8.3.1.1 Suspended Solids (SS) TCS-1000 Electrode Calibration
•
During calibration, select SS unit: mg/l or ppm
or select Turbidity unit: NTU, FTU, or FNU
•
SS and Turbidity calibration each provides 5 preset standard solution values for
selection:
SS: 800.0, 400.0, 200.0, 100.0, 10.0
Turbidity: 1000, 800, 100, 20.0, 1.00
•
If a turbidity unit is selected for calibration, the system will procced directly to
correction factor adjustment following standard solution calibration.
The procedure for TCS-1000 using suspended solids standard solution for two-point
calibration is as follows:
Press or to
select the first point closest
to the known solution
value.
Press to confirm it.
Press to confirm it.
Press or to
select the unit.
Press or to
adjust the Turbidity/S.S.
standard solution value.
Rinse the sensor with
distilled water and place
into the first solution for
measurement.
Press to confirm it.
Press to confirm it.
