View the reading history of a Monitored Asset

  • Updated

The reading history of a Monitored Asset is all past readings logged by its assigned sensor(s) over a specified period of time.

  1. Go to Monitoring > Monitored Assets.

  2. From the list, select the Name link of the asset to view.

  3. From Reading History, select View. The reading history is available in both a graphical and list view.

    The reading history data and graph is dependent upon the sensor type.

  4. By default, the first two sensors assigned to the Monitored Asset are selected. The readings of the selected sensor(s) are displayed in a graph view for the date range specified. To change the sensor data displayed, select or deselect a sensor.

    If the Monitored Asset has more than one sensor assigned, each sensor is displayed. Selecting all sensors displays the history of each individual sensor. The sensor name represents the type of sensor, last four digits of the sensor gateway MAC address, and sensor channel (example: Temperature-6D:F5-1).

  5. Set the date range to include.

     

    • Go to asset Creation Date: sets the start date to the date the Monitored Asset was added to your OneVue account.

    • Backward 1 Week: sets the current date range back seven days from the selected start date.

    • Start Date: sets the start date of the date range to display.

    • End Date: sets the end date of the date range to display.

    • Forward 1 Week: sets the current date range forward seven days from the selected start date.

  6. To view the reading data in a list view, select Show Readings.

Temperature reading graph detail (Temperature Sensor)

 

The reading line graph displays the reading data for the date range specified.

  • Reading: each reading is a single data point.

  • Y-axis: displays the unit of measurement and is automatically scaled based on the sensor Normal Condition setting value.

  • X-axis: displays the selected period of time

  • Top section (colored in pink): represents the measurement point that is above the sensor maximum Normal Condition setting value.

  • Bottom section (colored in blue): represents the measurement point that is below the sensor minimum Normal Condition setting value.

  • Sample Points: total number of readings within the date range specified.

Temperature calculated data

Displays the system calculated reading data for the date range specified.

  • Mean: the average mean value of the readings of the date range specified; the calculated value of the sum of all readings divided by the total sample points.

  • MKT (Mean Kinetic Temperature - temperature sensor only): a calculated single temperature that simulates the effects of temperature variations over a period of time. The calculation of MKT gives the higher temperatures a greater weight when computing the average than would a simple numerical average or arithmetic mean. This weighting is determined by a geometric transformation — the natural logarithm of the absolute temperature.

    Limit MKT to last 24 hours of data?: select the option to limit the calculation of the MKT for only the last 24 hours of logged readings, which reflects FDA recommendations to use a 24-hour calculation. The last 24 hours is based on the selected End Date. If this option is not selected, the MKT is calculated using all logged readings for the selected Start and End Date range.

Ambient Temperature reading graph detail (Temperature & Humidity Sensor)

 

The reading line graph displays the reading data for the date range specified.

  • Reading: each reading is a single data point.

  • Y-axis: displays the unit of measurement and is automatically scaled based on the sensor Normal Condition setting value.

  • X-axis: displays the selected period of time

  • Top section (colored in pink): represents the measurement point that is above the sensor maximum Normal Condition setting value.

  • Bottom section (colored in blue): represents the measurement point that is below the sensor minimum Normal Condition setting value.

  • Sample Points: total number of readings within the date range specified.

Relative Humidity graph detail (Temperature & Humidity Sensor)

 

The reading line graph displays the reading data for the date range specified.

  • Reading: each reading is a single data point.

  • Y-axis: displays the unit of measurement and is automatically scaled based on the sensor Normal Condition setting value.

  • X-axis: displays the selected period of time

  • Top section (colored in pink): represents the measurement point that is above the sensor maximum Normal Condition setting value.

  • Bottom section (colored in blue): represents the measurement point that is below the sensor minimum Normal Condition setting value.

  • Sample Points: total number of readings within the date range specified.

Differential Pressure graph detail (Differential Pressure Sensor)

 

The reading line graph displays the reading data for the date range specified.

  • Reading: each reading is a single data point.

  • Y-axis: displays the unit of measurement and is automatically scaled based on the sensor Normal Condition setting value.

  • X-axis: displays the selected period of time

  • Top section (colored in pink): if the normal condition is set to a negative pressure, represents an out of range reading due to a positive pressure reading.

  • Bottom section (colored in blue): if the normal condition is set to a positive pressure, represents an out of range reading due to a negative pressure reading.

  • Sample Points: total number of readings within the date range specified.

Water Leak graph detail (Water Leak Sensor)

 

The reading line graph displays the reading data for the date range specified.

  • Reading: each reading is a single data point.

  • Y-axis: displays the unit of measurement - either Dry (Normal Condition) or Wet (Out of Range).

  • X-axis: displays the selected period of time.

  • Top section (colored in pink): represents each reading point that is Wet (Out of Range).

  • Bottom section (colored in blue): represents each reading point that is Dry (Normal Condition).

  • Sample Points: total number of readings within the date range specified.

Contact Closure graph detail (Contact Closure Sensor)

 

The reading line graph displays the reading data for the date range specified.

  • Reading: Each reading is a single data point.

  • Y axis: Displays the unit of measurement - either Closed (Normal Condition) or Open (Out of Range)

  • X axis: Displays the selected period of time

  • Top section (colored in pink): Represents each reading point that is Open (Out of Range).

  • Bottom section (colored in blue): Represents each reading point that is Closed (Normal Condition).
