2Installation
Dear Customers,
Thank you for choosing ETG for your analysis system.
The NH3 GAS ANALYSER is designed for the continuous measurement of NH3. This system has been
designed with the intention to provide a system of high efficiency but at the same time intended for a user
even low knowledge.
Thanks to the software developed by ETG, the user is able to carry out a high performance and versatile
analysis in a few minutes.
The analyser is ready to use.
Plug the charger and connect it to your power plug.
Switch on “charge”: if the led on the charger is green, the analyser is fully charged; if is red, wait for green
light.
Please read this manual carefully.
2.1 electrical and pneumatic connection
the procedure is simple:
•Open the ETG6900 case.
•Inside you will find a terminal box of the following type:

•Connect the analog signal of the 4-20mA output of the NH3
•Then exit with the cables from the hole provided in the ETG6900 case (1)
•Make the pneumatic connections (2),(3)
•Connect the LAN cable (4), connect to the network with DHCP.
•Connect the power supply by connecting a cable to the rear socket of the ETG6900 (5)

3Measurement Graph
The program will displays graph, in real-time measurement. The origin of the axis time is made to coincide
with the beginning of the measurement session. You will see real time data in the upper side of the window
(“Last Measure”).
In the same screen of the software indicates the presence of any alarms with a reference code (that’s need
to be communicated to ETG for troubleshooting)
Fig. Main screen
If you click on "Reset Graph", the software, after asking for confirmation via a pop-up, start a new session
of measurement to a new origin of the time axis.
If you’re sampling ambient air remember to activate the internal pump
If you’re sampling gas from a pressure sampling point, be sure that this one it’s not higher than
100mbars! (in that case don’t activate the pump)
