1. Introduction
1.1. Description of the transmitter
C310 transmitters with display can be configured via keypad. It is possible to set the measurement units, to activate or not a
channel,...
Trend indicator : on the screen, a trend indicator represented by a rising arrow, a going down arrow or a stable arrow is
displayed above the measurement unit. It means the calculation of a moving average on the last hour ( 1) to compare with
a moving average on the last 5 minutes ( 2) :
•If 1 = 2, the trend is stable.
•If 1 < 2, the trend is upwards.
•If 1 > 2, the trend is downward.
This trend indicator is displayed after 5 minutes.
Indicator light : the indicator light indicates that the transmitter if powered on.

1.3. Protection tips of the sensor
It's extremely unwise to remove the protection tip of our hygrometry probes as
the sensitive element is very fragile even to light contacts. However, if you
have to remove the protection tip, take all possible precautions and avoid any
contact with the sensitive element.
To remove the protection tip, unscrew it or unclip it.

Enter a correction factor : this correction coefficient allows to adjust the transmitter according to data in air velocity of the
installation.
How to calc late it ? For example, the air velocity in your section is 17 m/s and the transmitter displays 16.6 m/s. The
coefficient to apply is 17 / 16,6 it means 1.024.
➢Press OK.
➢Enter the security code then press OK.
➢Go to “Parameters” line then press OK.

➢Go to “Probe 1” or “Probe 2” line (according to the channel of the air velocity/airflow probe) then press OK.
➢Use Up/Down/Left/Right arrows to enter a correction factor then press OK.
The correction factor must be between 0.2 and 2.
Enter an integration in air velocity : The air velocity measurement element of the transmitter is very sensitive and reacts
to air velocity changes. When making measurements in unstable air systems, the air velocity measurement may fluctuate.
The integration coefficient (from 0 to 9) makes an average of the measurement ; this helps to avoid any excessive
variations and guarantees a stable measurement.
New displayed val e = [((10 - Coef.) x New Value) + (Coef. x Old value)] /10
Example : C310 with hotwire (0-30 m/s) – Current measurement : 2 m/s – New measurement : 8 m/s
The air velocity source being unstable, the user selects a strong integration. Integration : 7. The variation is lower than 10
m/s, it is possible to apply the integration calculation formula.
Next displayed val e : ((2 * 8) + (7 *2 ))/10 = 3 m/s.

•Debimo blades (coefficient : 0.8165)
•le coefficient of the element (free coefficient)
➢Press OK.
Select the type of section : 3 selections are possible : rectangular or circular section or airflow coefficient.
•For the rectangular and circular sections : see chapter 3.6.1

This airflow coefficient allows to calculate an airflow from the pressure. It is indicated by the manufacturer of the devices
supplied with pressure connections (+ and -). From the square root of the measured pressure (Delta P) and from this
coefficient, you get the airflow. Airflow = CD x
√
Δpressure
The coefficient must be between 0.1 and 9999.9.
The available units for the reference unit are : Pa, mmH2O, inWg and mbar.
Enter a correction factor : this correction coefficient allows to adjust the transmitter according to data in air velocity of the
installation.
