Description
Le module d'entrée analogique TestScale vous permet de mesurer des signaux de tension d'entrée asymétriques ou différentiels avec des plages d'entrée programmables, tout en offrant une protection Ch-COM de ±30 V. Ce produit est compatible avec les distributions Linux courantes et peut être intégré avec des logiciels NI tels que TestStand, LabVIEW et SystemLink. Le driver NI-DAQmx est également inclus dans le module, avec un exemple de code et un support pour les langages courants tels que Python, C/C++, .NET et LabVIEW.
Les spécifications sont typiques dans les conditions suivantes, sauf indication contraire :
- Température ambiante de 0 °C à 55 °C. La température ambiante est définie comme la température à l'entrée du ventilateur de l'enceinte (prise d'air).
- Veuillez vous référer au sujet des considérations thermiques dans la documentation des backplanes sur ni.com/docs pour obtenir des informations supplémentaires sur les caractéristiques de température ambiante et les exigences de refroidissement.
- Toutes les tensions sont relatives à COM.

AI Absolute Accuracy
The following values are based on calibrated scaling coefficients, which are stored in the onboard EEPROM.
The following statements apply to the accuracy specifications across all voltage ranges:
- Accuracy at full scale is the summation of gain error, offset error, INL, and noise at full scale. Noise is assumed to be averaged with 10,000 samples, with coverage factor of 3 σ.
where
- A is the accuracy
- G is the gain error
- R is the reading
- O is the offset error
- INL is integral non-linearity
- Range is the voltage range, and
- Nsamples is the number of samples
- Assume internal temperature change since last self-calibration is within ±10 °C.
