1. Introduction
1.1. Description of the transmitter
The CPE 310-S and CPE 311-S can be configured via the keypad. It is possib e to set the measurement units, to activate or
not a channe ,...
Principle: the different settings are in the form of fo ders and sub-fo ders numbers. The digita codes are fu y detai ed in
this manua .
1.2. Description of the keys
–Up key: increments a va ue or a eve
–Down key: decrements a va ue or a eve
–OK key: va idates an input
–Esc key: cance s the input or goes back to the previous step
1.3. Protection tips of the sensor
It's extremely unwise to remove the protection tip of our hygrometry probes as
the sensitive e ement is very fragi e even to ight contacts. However, if you
have to remove the protection tip, take a possib e precautions and avoid any
contact with the sensitive e ement.
To remove the protection tip, unscrew it or unc ip it.

This function a ows to check on a measurement device (mu timeter, regu ator or automate) the proper functioning of the
outputs. The transmitter wi generate a vo tage (between 0 and 10 V) or a current (between 0 and 20 mA) according to the
setting of the type of output.
•For a 0-10 V output signa , the transmitter wi generate 0 – 5 or 10 V.
•For a 0-5 V output signa , the transmitter wi generate 0 – 2.5 or 5 V.
•For a 4-20 mA output signa , the transmitter wi generate 4 – 12 or 20 mA.
6.3.1 Connection configuration
Before carrying out the output diagnostics, a connections and configurations of the transmitter must be enab ed, to avoid
any damage on the transmitter and the mu timeter!
➢Se ect an output for the output diagnostic.

The atching mode is when the transmitter goes into a arms, it starts beeping and when it goes out of a arm (norma ) it
shou d continue beeping unti an operator acknow edges it.

8. F 500: Set the pressure measurement
This part a ows to set an integration coefficient, to perform an autozero, to set a de ay time between two auto-zeros.
In order to compensate a possib e drift of the sensor, it is possib e to add an offset and/or a coefficient to the va ue
disp ayed by the transmitter.
8.1. Perform an auto-zero
CPE 310-S and CPE 311-S transmitters have a manua auto-zero which guarantees a good re iabi ity of the measurement
in high and ow ranges.
The auto-zero compensates for any ong-term drifts of the sensitive e ement, with the manua adjusting of the zero.
To perform a se f-ca ibration:
➢Press Esc during 8 seconds.
8.2. Integration of the pressure measurement
The pressure measurement e ement is very sensitive and reacts to pressure changes. When making measurements in
unstab e air movement conditions, the pressure measurement may f uctuate. The integration coefficient (from 0 to 9) makes
an average of the measurements ; this he ps to avoid any excessive variations and guarantees a stab e measurement.
New displayed value = [((10 - Coef.) x New Va ue) + (Coef. x O d va ue)] /10
Examp e: CPE 311-S (0-1000 Pa) – Current measurement: 120 Pa – New measurement: 125 Pa
The pressure source being stab e, the user se ects a ow integration. Integration: 1, maximum admitted variation ±10 Pa.
The variation is ower than 10 Pa, it is possib e to app y the integration ca cu ation formu a.
Next displayed value = ((9 * 125) + (1 *120 ))/10 = 124.5 i.e, 124 Pa. If the new measurement had been de 131 Pa, the
next disp ayed va ue wou d have been 100% of the new va ue i.e, 131 Pa.
The transmitter is powered on.
➢Press OK.
➢Enter the activation code (see page 9).
➢Press OK.
➢Press Up key to go to F 500 fo der.
➢Press OK.
➢Set the integration va ue with Up and Down keys.
This value is between 0 and 9 with:
•Coefficient 0: no integration, important fluctuation of the displayed value
•Coefficient 9: maximum integration, more stable measurement display.
8.3. Delay times between 2 auto-zeros
It is possib e to set an interva between two se f-ca ibrations.
The transmitter is powered on.
➢Press OK.
➢Enter the activation code (see page 9).
➢Press OK.
➢Press Up key to go to F500 fo der.
➢Press OK.
➢Press Up key to go to F510 fo der.
➢Press OK.
The duration between 2 self-calibrations is displayed.
➢Set the duration with Up and Down keys.
This delay time must be between OFF (no self-calibration) and 60 minutes.
➢Press OK to va idate the duration.
