4.3 Setting the Conductivity sensor k factor
The 90-FL automatically recognises a k=10 sensor. If a k=10 sensor is being used, go directly to
section 4.4.
The 90-FL does not automatically recognise k=0.1 or k=1 sensors. When a k=0.1 or k=1 sensor is
used, the 90-FL must be set to the correct k factor before use.
To select a k=0.1 or k=1 sensor…
1. Select k factor entry ( →→ F4:Setup →→ F4:k factor).
2. The k factor entry screen is now displayed…
Select nominal k factor,
F1:k=.1 >F2:k=1
The arrow indicates the current selection.
Press if a k=0.1 sensor is being used.
Press if a k=1 sensor is being used.
Press to quit without changing the current setting.
Notes
1. The manual k factor selection is kept in memory when the meter is switched off.
2. The manual k factor selection is reset to k=1 during initialisation.
3. The 90-FL will always automatically recognise a k=10 sensor, regardless of the manual k
factor selection.
4. Calibration settings for k=0.1, k=1 and k=10 sensors are NOT stored separately.
The 90-FL requires re-calibration when a new k factor sensor is connected.
