''Calibration:  Initiates the calibration procedure tool.
<br>All current analyses and recording must be stopped prior switching to calibration.
The following dialog box is used to calibrate the inputs connected to a transducer.
[[Image:Reports_Tools_Ribbons_27.png|framed|none]]
* Channel: This is the channel to be calibrated. It can be selected using the drop-down list or the up and down arrow. It is available for calibration of all dynamic and DC inputs. When a channel is selected, the sensitivity and the offset are immediately updated.
* Reference: This is the transducer selected on the channel. It is necessary to select a transducer in order to calibrate the input. If the transducer used is not in the list, a default transducer can be used. Information about the transducer is displayed.
* History: See "Transducer" chapter p 82. This button is not available when a default transducer is selected, since it does not refer to unique transducer.
* Edit: Similar to the "new transducer dialog".
* Calibration type: This field is automatically updated, depending on the type of transducer selected.

|Calibration type
|Description

|Acoustic
|The transducer is a microphone

|Vibration
|The transducer is an accelerometer (possible unit in g or in m/s²)

<br><br>The area presents the current level on the DC input and is used to perform the calibration for two values. Once calibration is completed, the new sensitivity and offset are available.
* Apply: Applies the new sensitivity to the selected channel.
* Save: Applies the new sensitivity to the selected channel and saves the calibration information. This button is not available for a default transducer.
* Reset: Restores the current sensitivity of the transducer.
|}<br clear="all">
* Acoustic, vibration and frequency calibration: The spectrum measured is displayed. The frequency range is linked to the calibrator frequency. It is possible to right click in the plot area to perform an auto-scale on the Y-axis.
* Calibrator level: Indicates the level of the calibrator. This values is used to determine the new sensitivity of the transducer
* Calibrator frequency: Indicates the frequency of the calibrator. It is used to check that the maximum level measured is at the correct frequency. It is also used to select the best frequency range for the calibration. The most common calibrator frequencies are suggested. It is also possible to choose a user-defined frequency.
[[Image:Reports_Tools_Ribbons_12.png|framed|none]]
* New: Used to select a user-defined calibrator frequency
* Calibrate: Starts the calibration. The analyzer detects the maximum level, checks that frequency is near the calibrator frequency, and determines the new sensitivity.

NB: In case of 1-DSP analyzer with 4 inputs @ 51,2kHz connected to the octave plug-in, it is not possible to perform the calibration (DSP power limit reached). In such situation, down the sampling frequency to 25,6kHz or disconnecting the inputs from the octave plug-in for the time of the calibration will allow calibrating the sensors.

Detect TEDS: Start the sequence for detecting transducers (or missing one) equipped with an electronic datasheet inside (TEDS: Transducer Electronic Data Sheet) connected to the front end.
As the TEDS sequence occurs automatically when an input coupling is set to ICP<nowiki>+</nowiki>TEDS, the Detect TEDS button is used for re-checking after transducers or cables modifications. The result of check will be visible on the warning window and may lead to add new transducers to the TDB.
Only the inputs with their coupling set to ICP<nowiki>+</nowiki>TEDS will be checked.
[[Image:Reports_Tools_Ribbons_315.png|framed|none]]
Applying the ICP<nowiki>+</nowiki>TEDS coupling to any (set of) input(s) will activate a recognition sequence on the corresponding input(s).  The result can be the following;
* A new transducer (not in the current NVGate® transducers database) is connected to the corresponding input. NVGate® proposes to add the new transducer in the Transducer database. A dialog box lets the user change the transducer properties:
The content of the TEDS is used to fill the transducer properties. The data from the TEDS that have no correspondence in the ''transducer database'' are copied in the comment area. The name is proposed as the concatenation of type and serial number. User may change it.
[[Image:Reports_Tools_Ribbons_316.png|framed|none]]
* A known transducer (existing in the database) is recognized in the corresponding input. NVGate® will notice it in the log window (which is popped up automatically).
[[Image:Reports_Tools_Ribbons_14.png|framed|none]]
* There is no TEDS transducer connected to the corresponding input. A warning is issued in the log window for each input in this situation.
Warning the TEDS Detection will applies a negative voltage (-5 V) to the corresponding inputs, this may affect incompatible transducers.
OROS 3-Series TEDS management fulfills the IEEE 1451.4 - 2004 revision 1 standard for:

The transducers which are compatible with IEEE 1451.4 - 2004 revision 1 are automatically recognized by the OROS 3-Series analyzers.  In order to protect transducers that are electrically incompatible with the TEDS reading, there is a special coupling ''ICP <nowiki>+</nowiki> TEDS.''
All other transducers types will generate a warning specifying that they are not supported.
There are two ways to add a TEDS transducer to the transducers data base:
''Connect a TEDS transducer on a channel.''
Select ICP TEDS for the input coupling.
All the characteristics of the transducer are automatically detected.
A warning confirms that a new transducer has been detected.
The window below is displayed.

The new transducer is added to the transducer database.
* ''Used a TEDS File''
To use a TEDS file, click on New from TEDS file in the transducer database window.
By selecting the file, all the characteristics of the transducer are imported in the transducer database where anew transducer is added.
