8. Selecting k=10 or k=0.1 Sensors
The
901-C
automatically recognises a k=1.0 sensor. The
901-C
does not
automatically recognise k=0.1 or k=10 sensors. When a k=0.1 or k=10 sensor is
used, the
901-C
must be manually 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
and wait for 10 seconds.
2.
Press and HOLD the
key while switching the meter back on.
3.
The meter now displays the current manual k factor. For example…
k factor, k=10.0
k factor, k=10.0
Press the
or
keys to roll through the choice of k=10 or k=0.1 sensors.
4.
Press the
key to exit when the desired k factor sensor has been
selected.
The 901-C will now display its Model, Firmware Version and Serial
Number for approximately 4 seconds, before going on to Conductivity plus
Temperature mode.
Notes
The manual k factor selection is kept in memory when the meter is switched off,
even when the power supply is removed.
If a k=0.1 sensor is being used, this must be manually selected again when the
unit is initialised (see section 9).
The
901-C
will always automatically recognise a k=1.0 sensor, regardless of the
manual k factor selection.
Calibration settings for k=0.1, k=1.0 and k=10 sensors are
NOT
stored
separately. The
901-C
requires re-calibration when any new sensor is connected.
