Sauvegarder calibration date/heure

Bonjour,
Pour le moment, j'ai mon programme qui fonctionne bien, je calibre mon capteur et j'enregistre les paramètres dans un fichier .ini. Jusque là pas de problème.
Je voudrais lorsque j'enregistre que ça tienne compte de la date et l'heure a laquelle j'ai calibré, et de plus que lorsque je fait plusieurs calibrations que ça ne m'efface pas mon fichier .ini mais garde les données précédentes!!
En gros que mes paramètres forme une petite base de données pour avoir une archive!!!
Merci de votre aide
Résolu !

Bon pour le moment j'ai réussi à enregistrer la date et l'heure mais quand je visualise mon fichier.ini la date et l'heure sont erroné, ça me met que des zéros (voir piece jointe)

I want to read calibration data from a file

I have some calibration data from an experiment. There are 14 channels and the data is arranged in a spreadsheet 14 rows x 4 columns, where each column is a different constant from a best-fit equation of the form y = b1 + b2.x1 + b3.x2 + b4.x1.x2, per channel.
I need to get the data into labview so that I can use it during an experiment. Can anyone recommend the best way to do this? I've tried the 'read from spreadsheet file.vi' but can't get it to work. Any recommendations or example code? Or do you think it is better to use a text file?
Thanks
Dave

They do. From the Help file:
Reads a specified number of lines or rows from a numeric text file beginning at
a specified character ... can use this VI to read a spreadsheet file saved in text format.
Note: The underlining is my emphasis. Still, I understand what you're saying, and as I said, it's been poorly named from the beginning.

Signal express custom calibration data, where is it?

I have a PXI 1042 rack with 4472 modules. I am using Signal exress 2011.
I have setup with custom scaling for the channels (so that I can log in engineering units rather than volts).
I have just replaced the disk and reinstalled everything. I have got everything working BUT...
When I try to open a previous Setup file it no comes up with an error stating it cant find the calibration values!
Is the custom scaling calibration data stored outside the Signal express setup file, if so where is it?
Thanks
mike

Ok sorted.
Refitted old disc with previous system on it. Ran Measurement and Explorer and then exported the configuration data.
Fitted new disk, imported configuratio data and all the scaling is restored.
Useful lesson, I had always thought the scaling was held in the TDMS files but its in the .nce files from the measurment and Explorer.

Calibration data in X Series EEPROM

[Thanks again to the NI engineers that have prepared the X Series support for the MHDDK. Your work is much appreciated!]
I've been reviewing the X Series DDK manual and example code to get a handle on how things work, and I have
a couple questions about the calibration data that's retrieved from the EEPROM via eepromHelper and how it is used.
1) There are 4 AI "modes" containing 4 coefficients. What do these modes refer to? Do they have anything to do with different
ground reference modes (DIFF, RSE, NRSE)? I noticed that eepromHelper::getAIScalingCoefficients() only uses the coefficients
for the first mode (mode 0) to compute the scaling coefficients for a given voltage range. Is that OK no matter which ground
reference mode my application employs?
2) There is one AO "mode" containing the usual 4 coefficients. The eepromHelper reads in this mode as well as the different
voltage interval (gain, offset) pairs, but it doesn't use the mode coefficients to compute the scaling coefficients for a given
interval as is done for AI and as is implied in the DDK reference manual on p. 2-18. Instead, scaling coefficients are simply
the gain (C1) and offset (C0) for the chose voltage interval. Is the mode not relevant in the case of AO?
Sincerely,
Scott
Solved!

Hi Scott,
The AI Modes do not correspond to different ground references, but rather just the configuration for the AI frontend. The EEPROM actually has more information than the device needs. Therefore, as you have mentioned only mode 0 is used, this is because the other modes are not used.
The AO mode also does not use all of the data in the EEPROM. In this case, unlike the third order polynomial fit that is used for AI, the AO is simply a linear fit. Therefore only the gain and offset are used.

PXI-4071 Calibration Date Update

Is there a process to have the internal Calibration Date update [using the Cal Executive software] without running the adjustment-reverify routines?

Hi sbdata,
In general, unless an actual adjustment is performed, then the EEPROM is not written to and the calibration dates will remain the same. That said, if you open an external calibration and then close it, the calibrated date will be set to the current system time.

NI ELVIS calibration data

When I perform the self-calibration procedure* on my NI ELVIS workstations, where is the resulting calibration data stored? I found a file named %ProgramFiles%\National Instruments\NI ELVIS 2.0\NI ELVIS Cal.bin that contains "raw binary" data which I assume is some/all of the calibration data. Is this the file that contains all of the calibration data, or are there other locations (e.g., the Windows registry) where the Calibration Wizard stores the calibration data?
* Windows Start menu » All Programs » National Instruments » NI ELVIS 2.0 » Calibration Wizard

Hello,
Some of the functions available with ELVIS is because to the circuitry inside the ELVIS unit. These functions include the function generator and the power supplies. When you calibrate either of these, the data is stored in EEPROM on the ELVIS unit. Other functions, such as the DMM or oscilloscope, are performed by using the analog input channels of the DAQ card. Therefore, if you calibrated these analog input channels the data would be stored on the EEPROM of the DAQ card. The ELVIS calibration wizard, at least in NI ELVIS 3.0, only gives you the option to calibrate the functions that are available to calibrate on the ELVIS unit and not the DAQ card. If you wish to calibrate your DAQ card you can do so, but in a different program. I hope this answers your questions. If any of this is unclear please let me know.
Have a great day!

Date heure email courriel incorrecte

Bonjour à tous
J'utilise LV2013 et je souhaite envoyer des log par email. L'envoi se passe correctement mais la date et l'heure affichée dans la messagerie de réception sont completement fausses (du genre 1970 à 4h au lieu de 2013 à 11h30 par ex). Les PC utilisés sont pourtant à la bonne heure/date avec le bon fuseau horaire et les messages d'autres correspondants sont "normaux".
Avez-vous une solution de correction date/heure ?
Merci
Bruno

Bonjour à tous
Après avoir vérifié que le VI mail de LV8.6 n'avait pas de probleme avec les dates, j'ai "récupéré" les 2 VI (joint) qui géraient la date.
(Pour info, LV8.6 fabriquait "à la main" tout l'entête et les VI n'étaient pas verrouillés alors que dans 2013 tout est caché dans une boite noire).
Dans LV2013, j'ai ajouté cette nouvelle date dans l'entete du mail (image jointe). Bien que le mail contienne maintenant 2 dates:
To: ************
From: ************
Subject: Test champs "Objet"
Message-ID: <..............>
Date: ven., 30 août 2013 12:27:28 0400 <<<<<<<<<<<<<<<<<----- Date VI LV2013 ------
Date: Fri , 30 Aug 2013 12?27?29 +0400 <<<<<<<<<<<<<<<<<---- Date ajoutée -------
MIME-Version: 1.0
Content-Type: multipart/mixed; boundary=LVb0C9F335019FD0F7B6E4647E2743ABCF61
Gmail reconnait la bonne date. Par contre, le VI entete mail de LV2013 remplace les séparateur ( de la chaine d'heure par autre chose (?) ce qui fait que l'heure n'est plus reconnue. C'est un moindre mal, car dans le client de messagerie, le message s'affiche au moins avec ceux du jour et pas noyé au fin fond de la liste avec ceux de 1970 !
Il n'y a plus qu'à attendre la correction de ce bug dans la prochaine version de LV2013 et que le VI express Email accepte les pièces jointes...

Backup Nike + calibration data

Is it possible to backup your Nike + data in case you have to do a ipod restore? I know that run data can be backed up on nike site but I am more concerned about calibration data. I just don't want to have to recalibrate after restore.

Huzler. I don't know, But you could try the following. I haven't calibrated my Nike+ so I cannot be sure what you will see, but here goes......
Enable your Nano for disk use. When it is mounted (on a Mac) open up the disk from the desktop and see if there are any files/folders that relate to Nike+ or Calibration....if so, copy them to your Mac and keep them safe. If you then need to restore, copy these files back.....it might work!!
If you are rnnung a Win box, after enabling disk use, in my computer loacte your Nano and from the view menu select Show Hidden Files & Folders. Then look for the Nike+ or Calibration files as mentioned above.
Good luck.
Please post back if this works, it will be helpful to others.

Writing in sensor calibration data to my virtual channels in MAX using Labview.

System consists of a few pxi6713 cards, a 6527 digital input card and some scxi cards (1520, 1104c, 1125).
Every 3months or so we run a calibration on the testing stand which uses these cards, and the sensor ranges and physical ranges listed in MAX has to be manually entered each time.
I am looking for a way to do this automatically. This may be a problem, but we are using NI-DAQ legacy (perhaps if absolutely necessary we could goto daqmx).
I have figured out howto read virtual channel information from max correctly, but I have no understanding of trying to write calibration information to the virtual channels.
Any help is greatly appreciated!
Thank you!
jacob

Hi mak90,
There are no ways to change the sensor range and physical ranges
programmatically in Traditional DAQ. Under DAQmx, you have Scaling VIs,
Calibration VIs, Task VIs that allow you to change various settings in
MAX programmatically.
Please let us know if you have any further questions.
