It is possible to temporary change .usr file for special applications. To start NVGate with .usr different from the default one (NVGAte.usr) add the following to the command line: -usr=myfile.

=====Transducer group=====
This group manages the transducers database which is used by NVGate to automatically setup the inputs and trace front-end status at measurement time.
*

Database:  Opens the transducer database dialog
The left side displays all the transducers in the database in a tree form. They are grouped by type. For each type of transducer, there is a default transducer. The right side displays the information about the selected transducer.

*  ''New'': This button is available when a transducer or a transducer type is selected. It is called the "new transducer" dialog box. If a transducer is selected, all information related to the transducer is applied to the new transducer.
* ''New from TEDS file'': This button allows opening a file .ted and so creating a new transducer with its characteristics in the transducers database.
* ''Delete'': This button is not available when a default transducer is selected. It removes the selected transducer from the database.
* ''Modify'': This button is not available when a default transducer is selected. It is used to modify the characteristics of the transducer. Clicking on the modify or new button opens the transducer definition dialog box:

* Transducer type: Can be a pre-defined type (microphone, accelerometer...) or a user-defined type.
- General:
Magnitude, unit: Magnitude and unit associated with the transducer type
Identifier: Name that will be used to identify the transducer. This identifier must be unique. This is the only field that must be filled in. The others contain optional information.
Manufacturer: Name of the company that manufactures the transducer.
Model: Identifies the transducer.
Serial number: Unique identification, this must appear on the transducer itself.
Coupling: When the transducer is connected to an input, this coupling will automatically be set.
- TEDS:
By clicking on Get TEDS, a file .ted can be selected to set automatically the characteristic values of the transducer.
- Factory values: Sensitivity, offset, last calibration.
These values can usually be found on the calibration chart of the transducer. For maintenance calibration, use the update button to set the new values
- Current values: Sensitivity, offset, last calibration.
Displays the current sensitivity and offset. The update button may be used to set new values, in the event the transducer is not calibrated with NVGate<sup></sup>.
The history button is used to retrieve all calibrations that have been performed on the transducer.
- Applied sensitivity:
Factory: applies sensitivity of the calibration chart of the transducer.
Current: applies sensitivity read on the TEDS file of the transducer.
* Comment, transducer description: Free text area
* Conditioner: Has to be change if you use and X-Pod conditioner. The XPod is a device that can be fixed on the OR36<sub>2</sub>/OR38<sub>2</sub> side.

* Type: bridge signal conditioning for strain gauges, dynamic pressure, force and acceleration measurements.
* Gauge type: Full, Half or Quarter bridge mount. The completion resistors are included in the Xpod,
* Resistance: Bridge completion resistor: 120 or 350 Ohms for quarter bridge mount.
* Gain: Bridge gain: 10 or 100 depending on the required precision and range.
* Max current: the provided current can be limited to 30 mA up to 4 V and 12 mA up to 10 V.
* Excitation voltage: Each Xpod provides an excitation voltage from 0 to 10 V.
* Offset Comp.: Bridge offset comp: Can be used for manual balance of the bridge,
* New Transducer Type: This button is available when a transducer type is selected. A new transducer type is necessary when the pre-defined type does not fit the needs. It is used to gather transducers with the same magnitude.
[[Image:Reports_Tools_Ribbons_259.png|framed|none]]
* Magnitude: Magnitude that will be associated with the transducer type and all transducers of this type.
* Name: This name will be used to identify the type. It must be unique.
* Unit: Current unit of the magnitude.
* Default coupling: default coupling value that will be used when a new transducer is created. This value can be changed individually.
* Comment: Free text area

History:
This tool is used to see how transducer sensitivity and offset change over time. Information about every calibration is displayed, making it easy for the user to see if the transducer behavior is constant.
* Current sensitivity: This is the sensitivity level obtained during the last calibration. If the transducer has never been calibrated, the factory sensitivity is selected. This sensitivity is used when the transducer is selected on an input
* Current offset: This is the offset obtained during the last calibration. If the transducer has never been calibrated, the offset sensitivity is selected. This offset is used when the transducer is selected on an input
* Graph: Displays the calibration values. A pop-up menu is available by right clicking on the graph.
[[Image:Reports_Tools_Ribbons_261.png|framed|none]]
It is used to select the sensitivity graph, the offset graph or both. It is also possible to hide/display the factory values. There is also a marker to highlight the calibration.

Merge  multiple transducer databases into one. The merged TDB is the one currently used by NVGate (file: ''transducers.tdb'' located in the ''NVGate.exe'' directory)
Clicking on ''Merge'' open the database to merge browser. Both native (.cdb) and comma separated values (.txt) formats are available. For the csv, the format is the same as the export one, with one line per transducer.
In case of conflict (the same transducer does not features the same setup in the 2 databases) a specific dialog box is proposed.
[[Image:Reports_Tools_Ribbons_263.png|framed|none]]
Only conflict lines are displayed.
* On the left side the current NVGate<sup>®</sup> database called ''Mine''
* On the right side the imported one called ''Theirs''
The non-matching settings are written in red, and the current choice (the one which will be saved) is shown on a green background. The default choice is to save the current NVGate<sup>®</sup> settings (''Mine).''
The operator may apply 3 types of operations, selected by a right click on the line of interest:
* ''Use mine: ''The current NVGate<sup>®</sup> setting is kept. The calibration histories from the imported and current database'' ''are merged.
* ''Use theirs:'' The imported setting will be applied and saved. The calibration histories from the imported and current database'' ''are merged.
* ''Do nothing: '' The corresponding transducer is ignored and nothing is changed
At the end of the merge operation a summary of the modification is presented

Export:  Allows exporting the current database (file: ''transducers.tdb'' located in the ''NVGate.exe'' directory) in csv format.
The exported file contains one line per transducer with the following field.

Only the latest site calibration information are exported in the txt file.
