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,... 05/02/14 9.53 ◄Min/max Mesures Graphique► Alarm lights Left key Indicator light Esc key...
1.3. Protection tips of the sensor Sensitive It's extremely unwise to remove the protection tip of our hygrometry probes as element Protection tip the sensitive element is very fragile even to light contacts. However, if you to unscrew have to remove the protection tip, take all possible precautions and avoid any contact with the sensitive element.
2.1. Configuration of parameters Communication speed : between 2400 and 115200 bauds, 19200 bauds by default • Data bits : 8 bits • Stop bit : 1 bit • Parity : None • Flow control : None • Transmitter addressing : between 1 and 255 (automatically answers the requests from address 0) •...

3.1. Enter the security code To configure the transmitter, and for security purposes, a security code must be entered. The default code is 0101. ➢ Connect the transmitter. ➢ Wait until the initializing period is over. ➢ Press OK. “Code” is displayed with “0000” below. ➢...
3.2.1 Set the screen ➢ Press OK on “Screen” line. ➢ Press OK on “Contrast” line to set the contrast between 0 and 3. ➢ Use Up and Down keys to set the contrast then press OK. ➢ Go to the “Backlight settings” line with the Down key then press OK. ➢...
3.2.7 Modify the security code ➢ Press OK on “Security code” line. The following message is displayed : “Modification Security code?”. ➢ Go to “Continue” then press OK. ➢ Enter the current code. ➢ Enter the new code. ➢ Go to “YES” then press OK to confirm the new code. The transmitter displays a message indicating that the code has been modified.
3.2.11 Access to the transmitter information This part allows to access to the information about the transmitter, the boards and the probes. ➢ Press OK on “Information” line. screen is displayed with information about the transmitter (name, serial number, calibration date). ➢...
The transmitter displays the different types of outputs : 4-20 mA, 0-20 mA, 0-10 V or 0-5 V. ➢ Go to the type of required output then press OK. The output number is equivalent to the number of the displayed channel (ex : output 1 = channel1) 3.4.2 Set the minimum and maximum ranges ➢...
3.5. Configure the alarms This part allows to activate and define the alarms conditions on one or several channels. One channel must be configured at least (see chapter 3.3). If no channel has been configured, the transmitter will indicate that the alarms configuration is impossible.
Monitoring The alarm goes off when the measurement is outside the low and high thresholds. When an audible alarm goes off, it is possible to acknowledge it pressing OK key on the transmitter. 3.5.2 Set the alarm in rising or falling edge The alarm mode “Rising edge”...
The alarm mode “Transmitter state” is selected. ➢ Go to the “Configuration” line then press OK. ➢ Press OK on the “Condition selection” line. The transmitter displays the list of alarms conditions : Ambient temperature too high* • Ambient temperature too low* •...
3.6. Configure the probes, boards and normative values This part allows to set the following parameters : for an air velocity and airflow probe : (hotwire or vane) : the type of section, the correction factor, the in air • velocity and the compensation in atmospheric pressure (only available for hotwire probes) For a pressure board : air velocity and airflow (if the option is activated), the integration in pressure, the purge •...
New displayed value = [((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.
