Quelle est la vitesse de rafraîchissement de nos cartes de communication pour les produits de la famille "PAX"?

Réponse: 

  1. Transmission RS232:
    2 à 50 ms 

  2. Transmission RS485:
    50 à 100 ms

  3. Lecture du PAX:
    1, 2, 5,10 mesures / secondes (Menu 4 – paramètre :  dSP-t)

  4. Sortie Analogique: 
    Un réglage du paramètre udt à 0 (menu 8 – paramètre : udt) entraîne une fréquence de rafraîchissement de 20 fois par seconde.

What is the measurement and refresh rate of a display of the PAX series and its analog output (CARD-CDL10) ?

[answer] =>

Answer :

 a)     Display

 The measurement speed depends on 2 parameters:

  1. The parameter Filtr (menu 1-INP) adjustable from 0.0 to 25.0 sec and can be disabled by the parameter bANd (menu 1-INP) (see user manual).
  2. The dSP-t parameter (Menu 4 - SEC) can be set to 1, 2, 5, 10 or 20 measures / sec. which allows to configure the display refresh rate.
  3. In the case of the speed of 20 measurements / sec., the internal zero correction is disabled in order to allow the fastest response.

Step response:

  • 200 msec. max. to within 99% of final readout value (digital filter and internal zero correction disabled) (Filtr = 0.0 and dSP-t = 20).
  • 700 msec. max. (digital filter disabled, internal zero correction enabled) (Filtr = 0.0, dSP-t = 10).

 

b)     Analog Output

 The parameter Udt (menu 8 - Out) adjusts the refresh time from 0.0 to 10.0 sec. The value 0.0 corresponds to the maximum speed, ie 20 refreshes per second.

Update time:

  • 200 msec. max. to within 99% of final output value (digital filter and internal zero correction disabled)
  • 700 msec. max. (digital filter disabled, internal zero correction enabled)
