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.
: Serial number of the sensor (engraved under the sensor
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
2
O Sensor Param
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.
: Serial number of the sensor (engraved under the sensor
connector). The
same serial number is used for the gas sensor and humidity
sensor.
•
H
2
O Param C1
to
C10
: The ten parameters of the moisture sensor in a
normalized
format (integer numbers).
