6.4 Contacting Conductivity
Measurement Programming
The section describes how to configure the 56 analyzer for conductivity measurements using
contacting conductivity sensors. The following programming and configuration functions are
covered.
1. Measure: Conductivity, Select Conductivity, Resistivity, TDS. Salinity or % conc
2. Type: 2-Electrode Select 2-Electrode or 4-Electrode type sensors
3. Cell K: 1.00000/cm Enter the cell Constant for the sensor
4. Measurement units
5. Filter: 2 sec Override the default input filter, enter 0-999 seconds
6. Range: Auto Select measurement
Auto-range or specific range
7. Temp Comp: Slope Select Temp
Comp: Slope, Neutral Salt, Cation or
Raw
8. Slope: 2.00% / °C Enter the linear
temperature coefficient
9. Ref Temp: 25.0 °C Enter the Refer-
ence temp
10. Cal Factor: default=0.95000/cm
Enter the Cal Factor for 4-Electrode sensors from the sensor tag
To configure the contacting conductivity measurement board, access the Program screen by
