Measurement configuration
K-M1100 sensor configuration
1. Select Configure channel from the Measurement menu:
Option Description
Sensor Selec the sensor model H or L
Medium Select Liquid or Gas.
Gas unit type Select Partial , Fraction , or Dissolved .
Gas unit When a composite unit is selected the unit will change depending on the range of the
value to display. The list of available units depends on the gas unit type selected.
Liquid For the K1100 sensor this option is locked on Water . For the M1100 low range sensor,
choose between Water and Beer . For the M1100 high range sensor, choose between
Water , Beer , Wort , Wine and Carbonated drink .
Display resolution A maximum of 5 digits can be displayed. Decimals can be limited to 0, 1, 2 or 3 for
easier reading. The resolution affects only the data displayed, not the resolution of data
measured and stored.
T cut off If this temperature is exceeded the measurement session is suspended and the system
displays a
HOT alarm message. The system resumes when the temperature drops to
90% of the specified temperature. It is recommended to Enable this feature to maximize
sensor life and system performance.
T cut off value Set to 5°C above the sample temperature.
K-M1100 advanced configuration
Note: The offset feature described below should be used for minor measurement adjustments only, and not as an
alternative to a sensor calibration. Make sure your sensor has been correctly calibrated before applying this feature.
1. Select the Advanced button on the Measurement configuration screen:
Option Description
Offset enabled Check this box to enable the user measurement offset option. If checked enter an
offset value or a target value:
Offset value Enter an offset value to manually adjust the measurement value. If the gas unit type or
gas unit (defined in the
Measurement configuration screen) are changed the offset
value is automatically reset to zero.
Measurement This field cannot be updated. It shows the current measurement value with the offset
applied.
Target value Enter a target measurement value. The offset value is automatically computed so the
displayed measurement value will be equal to the target value.
Compute offset Select this button to recompute the offset value at any time during the measurement
process. The offset value will be computed based on the current and target
measurement values.
Out of range
protection Check this box to enable the out of range protection (recommended). When enabled
and the measured value exceeds the instrument specification, the measurement
interval will be increased to 1 minute to protect the lifetime of the sensor spot. If
disabled, the lifetime of the spot can be negatively impacted if the sensor is exposed
to high oxygen concentrations for long periods of time.
