16. Selecting k=0.1 or k=10 Conductivity Sensors
The
WP-81
automatically recognises a k=1.0 sensor. The
WP-81
does
not
automatically recognise k=0.1 or k=10 sensors. When a k=0.1 or
k=10 sensor is used, the
WP-81
must be set to the correct k factor before
use. The following procedure describes how to select a k=0.1 or k=10
sensor.
1. Switch the meter
OFF
.
2. Connect the k=0.1 or k=10 sensor.
3. Press
and HOLD
the
key while switching the meter back on.
4. The k factor selection menu is now displayed (only if the k=0.1 or k=10
sensor is connected)…
Select F1:k=0.1
k factor >F2:k=10
The arrow indicates the current selection.
5. Press
to select a k=0.1 sensor.
Press
to select a k=10 sensor.
Press
to quit buffer selection and retain the current setting.
Notes
1. The manual k factor selection is kept in memory when the meter is
switched off, even if the battery is removed.
2. The manual k factor selection is reset to k=10 during initialisation.
3. The
WP-81
will always automatically recognise a k=1.0 sensor,
regardless of the manual k factor selection.
4. Calibration settings for k=0.1, k=1.0 and k=10 sensors are
NOT
stored
separately. The
WP-81
requires re-calibration when a new k factor
sensor is connected.
