Test object Verification criterion
Sensor module
Sensor Checks whether the sensor works as per the specifications.
Reference temperature Checks whether the reference sensor works as per the specifications.
Sensor drift warning limit
exceeded Checks whether the configured warning limits are exceeded.
Sensor drift alarm limit exceeded Checks whether the configured alarm limits are exceeded.
Sensor information
Number of self-calibrations Displays all the self-calibrations executed up to now. This value cannot be
reset.
Deviation Displays the deviation of the measured value from the reference
temperature.
Adjustment of the measurement Displays the adjustment of the calibration deviation.
Monitoring parameters
Device temperature min: Displays the minimum electronics temperature measured in the past
(peakhold indicator).
Device temperature max: Displays the maximum electronics temperature measured in the past
(peakhold indicator).
Sensor min value: Displays the minimum temperature measured in the past at the sensor
input (peakhold indicator).
Sensor max. value: Displays the maximum temperature measured in the past at the sensor
input (peakhold indicator).

If the verification fails, try again or contact the Service Organization.
8.6.4 Heartbeat Monitoring
Calibration information is logged in addition to the verification parameters.
HART variable Output Unit
PV Temperature °C/°F
SV Device temperature °C/°F
TV Calibration counter -
QV Calibration deviation °C/°F
Monitoring information can be read out and analyzed as described below:
A higher-level controller is configured in such a way that calibration deviations and the
calibration counter are saved when the calibration counter changes. This type of function
is supported by Hauser's Advanced Data Manager Memograph M RSG45, for
example. The following table provides a sample overview of the monitoring analysis using
the Field Data Manager software MS20:
