Sensors Parameters

3.6.1.1 Gas Sensor Param
The Gas Sensor Param function gives access to the parameters of the gas
sensor. Each gas sensor has its own set of parameter values; the values are
indicated on the Test Certificate and Data Sheet (for an example, see Figure 3-12)
supplied with the Hydran M2-X. These options do not allow you to modify the
displayed values. To change the values, use Install New Sensor (see Section 3.6.2).
The gas sensor parameters are:
• Gas Serial No.:
connector). The same serial number is used for the gas sensor and humidity
sensor.
• B, M, N, S and A1 to A6: The ten parameters of the gas sensor in a normalized
format (integer numbers).
– The Hydran M2-X computes the gas level in ppm by performing two readings:
the sensor temperature (provided by the thermistor incorporated in the
sensor) and the gas sensor output (gas level). The calculation also requires
these ten parameters (from B to A6).
– These ten parameters characterize the behavior of the gas sensor by
modeling its response according to the temperature.
– The values of these ten parameters are stored in the Hydran M2-X's
nonvolatile memory (see Section 2.3.4.3).
• Gas Param CkSum: Checksum of the above values. This value is added to the list
to avoid erroneous values from being entered.
Note: The Hydran M2-X uses the proven technology of the Hydran M2-X sensor. For a
complete description, see Section 2.4.
3.6.1.2 H O Sensor Param
2
The H2O Sensor Param function gives access to the parameters of the moisture
sensor. Each moisture sensor has its own set of parameter values; the values are
indicated on the Test Certificate and Data Sheet (for an example, see Figure 3-12)
supplied with the Hydran M2-X. These options do not allow you to modify the
displayed values. To change the values, use Install New Sensor (see Section 3.6.2).
• H2O SerialNo.:
connector). The same serial number is used for the gas sensor and humidity
sensor.
• H
O Param C1 to C10: The ten parameters of the moisture sensor in a
2
normalized format (integer numbers).
