Park (fleet) management

Indicators of metrological operations to be renewed (certificates/maps) allow you to identify the metrological actions to do in priority.

Measurement chains

In this screen, you will find all the metrological information related to a measurement chain (device + sensor).

1. Search fields by serial number
2. Filter by type of operation: Calibration, verification, with or without modelization…
3. Import metrological reports: Possibility to import JRI metrological reports by using a drag/drop of files from your computer
4. Filter by compliant/non-compliant chains
5. Serial number of the measurement chain
6. Date of metrological operation
7. Type of metrological operation: Calibration, verification, with or without modelization…
8. Metrological certificate name: downloadable by clicking on the button ⬇️
9. Name of the operator who performed the metrological operation
10. Conformity (compliance): can be modified by clicking on it
11. Error: Deviation from the standard
12. Uncertainty: Sum of the uncertainty components
13. Error modelization equation: Correction coefficients a, b, c
14. Expiry date of the certificate

Modelization application

When importing (manually or automatically) new COFRAC calibration certificates or verificationreports made by JRI with an error modelization, you can choose whether or not to apply this modelization in order to adjust your measuring chains.

• Following a drag’n’drop: Select a measurement chain and click on “SEND”.

• Following automatic addition: In the measurement chain list, a button opens a window. Select the measurement chain and click on “SEND”.

In both cases, once the modelization has been sent, an adjustment is made on the measuring chains based on the correction parameters of the certificate.

Click on the button 👁️ to :

• see DETAILS of the metrological operation (Type, date, error, uncertainty, conformity, document, operator)
• see MODELIZATION: Correction coefficients, variance, and co-variance
• see LEVELS: The measurements used, as well as the results obtained (Standard deviation, error and uncertainties)
• DELETE: Metrological operations can be deleted, but only if the profile has “Delete a metrological operation” rights. The delete button leads to a screen where a reason must be entered. It is not possible to delete a metrological operation which has sent a command to the device in question, or if the device is a labguard (error message top right).

Drift analysis

Selection of the measurement chain:

Choose a measuring chain in the list to start the drift analysis on a specified period. The following graph or table is displayed: - Error of each operation with respect to the standard - Error in relation to the previous calibration (drift) - Error in relation to the first use.

It is possible to print the graph or to switch to table display.

Periodicity Optimization

This feature allows to estimate when an adjustment (by modelling) will be necessary on a chain (If error >or< predefined MPE). This estimation is possible thanks to the drift analysis.

- Part 1: Errors Summary

The following elements are displayed:

• The name of the measurement chain and the period of the drift analysis
• The error graph for each calibration point (here -40°, 0° and +40° C)
• The simulated error graph obtained using the least squares method (in red)
• The MPEs in the form of thresholds which are displayed by clicking on each point (here +/- 0.5°C)

- Part 2: Estimation of the drift

• The simulated error today
• The expected date of exceedance of the MPE
• The calculated annual average drift

- Part 3: Periodicity management

• The current periodicity calculated according to the last operation performed (calibration or verification)
• The periodicity deduced from the drift analysis with an invitation to perform an adjustment if the calibration error exceeds the MPE.
• The choice of whether or not to apply the new periodicity: At the end of the defined time (minus the number of days defined in the metrological alarms), the user will receive a metrological alert e-mail. And the oven will be in metrological alarm when the new period is exceeded.

Pending Certificates

MySirius displays all metrological certificates issued by JRI if you order a new digital probe or measurement chain with a metrological certificate done by JRI. Until the equipment is installed and detected by MySirius, the certificates are visible and downloadable from this page. Once the equipment is installed, the associated certificates are displayed in the “measurement chains” page or in the metrological details of the monitored unit.

Equipment & Programs

This section allows you to declare standards and environments and to use them to create single or multi-point calibration programs.

Standards (reference measuring chains)

1. Create a new standard chain by clicking on the ADD button.

• Select the CONNECTED type for the NOVA SPY, NANO SPY and LORA SPY standard chains then choose the corresponding serial number in the field “Measurement chain”.

• Select the MANNUAL type to declare a generic standard (except NOVA SPY, NANO SPY and LORA SPY range). It is imperative to declare the measurement chain to be used to display it in the list of measurement chains. Otherwise, use the button “Add a generic measurement chain” to create a new one. It is necessary to select type of chain CUSTOM.

• Refer to the calibration certificate of your standard to enter the correction coefficients a,b,c if necessary. If there’s no correction of the read value, put a=0,b=1,c=0

Complete the rest of the form (choice of uncertainty model + add document) and click on SAVE

2. Once the standard chain is added to the list, it can be modified by clicking on it.
3. Select a standard chain to hide (disable) it using the . A new selection and then a click on allows a standard to be reactivated.
4. Generate a life sheet for each standard. Each time a modification is made, the life sheet is updated.

Calibration environments

Declare your calibration baths, ovens and climatic or thermostatic chambers used to perform your calibrations.

Same operating principle as for adding a standard (Add, click on the name to modify, select to activate/deactivate)

Programs

Once the standard chains and environments have been added, they can be combined to create single (Level1) or multi-point (Level 2) calibration programs (minimum 4 for modelization)

• Create a new program using the ADD button
• Enter the correct number of LEVELS (calibration points) and click on APPLY.
• Enter a standard chain and a calibration environment for each level.
• The arrows can be used to apply the selected items used from one level to another or select them for all levels.
• Click on SAVE
