## Abstract

A method and a system for reproducing a calibration certificate of an electronic instrument having at least one electronic storage means, the method involving separating the calibration certificate data into a first subset of data, which is calibration specific, and a second subset of data, which is document descriptive; defining a set of meta data about the second subset of data; storing the first subset of data and the set of meta data in the instrument's electronic storage means; storing the second subset of data in a computing device separated from the electronic instrument; and reproducing the calibration certificate by uploading the first subset of data and the set of meta data to the computing device and reconstructing the calibration certificate from the uploaded first subset of data set of meta data and the second subset of data.

## Claims

### Claim 1

A method for reproducing calibration certificate of an electronic instrument having at least one electronic storage unit, the method comprising:
separating calibration certificate data into a first subset of data, which is calibration specific, and a second subset of data, which is document descriptive;
defining a set of meta data about the second subset of data;
storing the first subset of data and the set of meta data in the instrument's electronic storage unit;
storing the second subset of data in a computing device separated from the electronic instrument; and
reproducing the calibration certificate by uploading the first subset of data and the set of meta data to the computing device and reconstructing the calibration certificate from the uploaded first subset of data, the set of meta data, and the second subset of data.

### Claim 2 (depends on 1)

The method of claim 1, wherein the meta data indicates a calibration certificate layout, content, and/or format.

### Claim 3 (depends on 1)

The method of claim 1, wherein the meta data indicates a calibration certificate layout, content, and format.

### Claim 4 (depends on 1)

The method of claim 1, comprising:
storing the second subset of data in an App or application program,
wherein the second subset of data includes a certificate of calibration template or templates, which contain layout, formatting, and static content of the calibration certificate.

### Claim 5 (depends on 3)

The method of claim 3, wherein the App or application program has the ability to create dynamic content based on the first subset of data.

### Claim 6 (depends on 3)

The method of claim 3, comprising:
storing an image of a calibrator signature or calibrator mark, which is then used by the App to incorporate on a regenerated calibration certificate.

### Claim 7 (depends on 1)

The method claim 1, where the electronic product is an industrial or measuring instrument.

### Claim 8 (depends on 7)

The method of claim 7, further comprising:
separating a data store from the industrial or measuring instrument into two physical parts, including a sensor data store and a transmitter data store.

### Claim 9 (depends on 8)

The method of claim 8, further comprising:
integrating and building in the communication link into an external computing device.

### Claim 10 (depends on 1)

The method of claim 1, further comprising:
recalibrating, using an App, the electronic product; and
storing updated calibration certificate contents into the product's data store.

### Claim 11 (depends on 1)

The method of claim 1, further comprising:
recalibrating, using an App, the electronic product; and
storing a separate new data record or calibration certificate, leaving previous entries available.

### Claim 12 (depends on 11)

The method of claim 11, further comprising:
storing a calibration certificate history or record; and
subsequently, making the calibration certificate history or record available for later regeneration from memory contents of the product.

### Claim 13 (depends on 1)

A system for reproducing a calibration certificate of an electronic instrument having at least one electronic storage unit, the system comprising:
an external computing device,
wherein the system is configured to execute the method of claim 1.
