LaMotte 5 Series TDS Meter - Manual (Page 16)

Selection of Automatic or Manual Calibration
This meter is capable of performing either automatic (CON 6 only) or manual
calibration.
In the automatic calibration mode, the meter (CON 6 only) automatically
detects and verifies the appropriate known calibration standards solutions
being calibrated before accepting these particular calibration standards as one
of the calibration values in a specific measurement range. This automatic
calibration mode makes the manual calibration procedure unnecessary.
The calibration standards used for automatic calibration are:
Meter Normalization
Temperature Calibration Standards (Range)
CON 6 25 °C 1. 84 µS (for 0 – 200 µS/cm)
2. 1413 µS (for 0 – 2000 µS/cm)
3. 12.88 mS (for 0.00 – 20.00 mS/cm)
4. 111.8 mS (for 0.0 – 200.0 mS/cm)
20 °C 1. 76 µS (for 0 – 200 µS/cm)
2. 1278 µS (for 0 – 2000 µS/cm)
3. 11.67 mS (for 0.00 – 20.00 mS/cm)
4. 102.1 mS (for 0.0 – 200.0 mS/cm)
Table 1: Conductivity Calibration Standards for Automatic calibration.
In the manual calibration, non-standard calibration values can be used for
calibration. The appropriate values can be manually input as the desired
calibration standards in each specific range. This is useful in situations with
customized calibration standards that are unique to an application.
To select Automatic or Manual Calibration settings, refer to Automatic
Calibration for more information.
