5.3 Setting the TDS sensor k factor
The
90-FL
automatically recognises a k=10 sensor. If a k=10 sensor is being used, go directly to
section 5.4.
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.
