Certificate fields
The certificate example is shown in Calibration certificate. The description of the contents of its fields is presented in the table below.
Certificate Number
Generated by app.
Calibration Date
Date of calibration
Set by app.
Issued by
Issuing company name
Address
Entered into “Info” form.
Customer
Sensor user company name
Address
Entered into “Info” form.
Customer's representative
Person representing the customer
Entered into “Info” form.
Customer's address
Address where the calibration takes place.
Entered into “Info” form.
Next calibration
Date of the next calibration.
Label “Next calibration”, shows the date of the next calibration calculated by adding the B3 “Calibration report interval” value to the current calibration date.
Calibration environment
Text “Onsite calibration” plus temperature and humidity.
Temperature and humidity entered into "Define sensor" form.
Calibration Method
Description of method.
Uncertainty of Measurement
Description of uncertainty.
Reference Instrument Type
Type and S/N of the reference instrument
Set by app basing on BT scan.
Reference sensor
S/N and certificate number of the reference sensor
Entered manually when a reference sensor is connected in the app.
Reference Sensor Adjustment
Reference sensor adjustment value.
Taken from reference sensor certificate. Filled-in automatically for WLREF. In case when two adjustments values are used as described in Reference readings handling, only the first one used is presented in this field.
Object
B3 object name or filled-in object name for manual mode.
Set by app basing on data from B3 or entered into "Define sensor" form.
Measuring Point
Measuring point name
Set by app basing on data from B3 or entered into "Define sensor" form.
Sensor Type
Type of calibrated sensor.
Set by app basing on data from B3 or entered into "Define sensor" form.
Sensor Serial Number
Serial Number of calibrated sensor.
Set by app basing on data from B3 or entered into "Define sensor" form.
Sensor Resolution
Resolution of calibrated sensor.
Set by app basing on data from B3 or selected in "Define sensor" form.
“Temperature readings” table
Temperature readings
Temperature readings of reference and calibrated sensors taken at the same minute during 10 consecutive minutes, starting after delay set in "Define sensor"form. The reference readings shown in the table are adjusted as described in Reference readings handling.
Average Reference Sensor Temperature (Tr) °C
Average of the reference sensor readings.
Calculated average of the reference sensor readings. 10 adjusted reference readings are summed up and divided by 10. The result is then rounded to 2 digits after the decimal point.
Average Calibrated Sensor Temperature (Tc) °C
Average of the calibrated sensor readings.
Calculated average of the calibrated sensor readings. 10 calibrated sensor readings are summed up and divided by 10. The result is then rounded to 2 digits after the decimal point.
Temperature adjustment (Tr-Tc) °C
Calculated adjustment value.
Average reference minus average calibrated sensor temperature.
Uncertainty
Uncertainty of measurement.
Calculated basing on the reference sensor parameters, calibrated sensor resolution and measurements variance.
Released on:
Date when the certificate was signed
Set by the app.
Released by:
Name and family name of the user signing the certificate
Set by the app basing on the B3 user signing the certificate or taken from "Info" form in case of manual calibration.
