10. CONFIGURATION OF THE PARAMETERS
Calibration
Wire resistivity compensation
The resistance value of the conductivity
probe wire must be specified. Entering
this value correctly will affect the result
of the temperature measurement.
Wire capacity compensation
If non-automatic cable capacity
compensation is used, the impedance
value measured with a dry probe must
be entered here. This eliminates the
effect of cable capacity on the
measurement.
TC compensation constant
• Acids: 1.0 - 1.6% /°C
• Bases: 1.8-2.2% /°C
• Salts: 2.2 - 3.0% /°C
• Drinking water: 2.0% /°C
• Ultra pure water: 5.2% /°C
Reference fluid
If the probe K factor is not specified, the meter can be calibrated using a reference
fluid. This value should only be entered during calibration, otherwise it will result a
false calibration and the measurement will not be real. When the conductivity probe
is in the reference fluid at 25 degrees Celsius,you can enter the value of the
reference fluid and calibrate the instrument by pressing the
Send button. After this
operation you can see, that the value of the K factor has changed.
