Introduction
Corvus is a Photo Ionisation Detector (PID) specifically designed to monitor VOC gas concentrations within
indoor environments. It also logs temperature, relative humidity and barometric pressure to help diagnose
potential sources of VOC’s.
Multiple Corvus instruments communicate together via a low power wireless mesh network, this offers the
convenience of downloading data from multiple slave instruments from a single Master instrument.
CorvusPC software also offers a dynamic range of tools that make analysing data and creating reports quick
and easy.
Setup
Please download and install CorvusPC software from the Ion Science website:
http://www.ionscience.com/customer-support/instrument-software
CorvusPC software is compatible with Microsoft Windows XP or later versions.
IMPORTANT
* All Corvus instruments are supplied setup as ‘Slave’ instruments with the Group name ‘A’.
* To create a network of Corvus instruments a Master is required; any Corvus Slave can be setup as a
Master using the CorvusPC software. Settings can be sent to multiple Corvus Slave instruments wirelessly
via a Master if it shares the same network Group name.
* Slave or Master Corvus instruments will not communicate with other Corvus instruments with different
group names.
* Before deploying Corvus instruments in a location make a note of which Corvus instrument is placed in
which location. Each Corvus has a unique serial number (eg. CV 000001) that can be used as a reference.
* Ion Science strongly recommends creating and testing a Corvus network before it is deployed.
Connect Corvus to CorvusPC software
Open CorvusPC software on a computer. Connect power to a Corvus instrument using the power adaptor
supplied with the instrument. The LED on the Corvus will flash BLUE and RED. Use the USB cable from the
accessory kit (Part number: A-877206) connect between the Corvus and the Computer.
Failure to use the supplied USB cable may invalidate the EMC certificate.
Corvus used in isolation.
There may be applications where a network of instruments is not required or not possible.
All Corvus instruments can be used in Isolation. Simply connect each Corvus to the CorvusPC software via
the USB cable and set a unique Group name. Data will be stored in the Corvus instrument and must be
downloaded via the USB connection.
Corvus used in a network
It is strongly recommended a network is setup and tested before deployment.
When each Corvus is connected to CorvusPC for the first time a message will appear asking if this
instrument is to be set as a Master.
A Master instrument is required to control each group of up to 20 Corvus instruments.
Data logging
Data is stored on each Corvus and is transmitted to the Master of that group. Should wireless transmission
be interrupted data will be stored on each Corvus and then forwarded to the master when wireless
connection is regained.
If wireless communication is permanently lost, data can be downloaded via USB from each Corvus
instrument. CorvusPC recognises when an instrument is in a group and will collate data from separate
instruments together. Data can therefore be viewed as if downloaded from a Master instrument.
