Statements
Responsibility for Use
The Corvus instrument detects and data logs a wide range of Volatile Organic Compound gases. It also
measures and Data logs Temperature, Relative humidity and Barometric pressure. The Corvus instrument
has many selectable features allowing it to be used in a variety of ways. Ion Science Ltd accepts no
responsibility for the incorrect adjustment of features that cause harm or damage to persons or property.
Inadequate performance of the gas detection equipment described in this manual may not necessarily be
self-evident and consequently equipment must be regularly inspected and maintained. Ion Science Ltd
recommends that personnel responsible for equipment use a regime of regular checks to ensure it performs
within calibration limits, and that a record be maintained which logs calibration check data. The equipment
should be used in accordance with this manual, and in compliance with local safety standards.
IMPORTANT
It is important the responses from the sensors are checked before being deployed.
Quality Assurance
Corvus has been manufactured in compliance with ISO9001:2008, which ensures that the equipment
supplied to our customers has been designed and assembled reproducibly, from traceable components, and
leaves Ion Science Ltd calibrated to stated standards.

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.

The CorvusPC software program is required to setup, calibrate and deploy the Corvus instrument; it is
available for download from the Ion Science website: http://www.ionscience.com/customer-support/instrument-software
!
Main screen
!
CorvusPC has 4 large buttons that appear on all main screens.
!
Live view
Show Corvus instruments currently in communication with CorvusPC. A Master Corvus must be
connected via USB, other Corvus slave in that group will also be displayed.
!
! History view
Show all Corvus instrument currently connected and previously connected.
Information
Displays software version information, offers access to software upgrades and access to the user
manual. If a new version of software is available it will appear in a dialogue box, to upgrade simply
press the ‘Install Upgrade’ button.
Archive
Access previously saved data and facility to analyse and export data.!!
!
Button functionality
Settings
This button gives access to the setup screen. Changes to settings are transmitted to all Corvus in
the group.
View data
Allows the user to view downloaded data in graphical form
Export data
Data from a single data is exported as a csv format allowing it data to be used in MS Excel.
Export multi data
Data from multiple instruments can be exported csv format allowing it data to be used in MS
Excel.
!
Delete Data
This button deletes previously saved data .!
Air Vision
Data can be analysed by importing a user defined map and placing Corvi monitors in the
monitoring location. The presence of VOC’s is then highlighted on the map offering a quick
method of identifying gas presence and migration.
Start logging
When pressed all Corvus connected to the group will start logging.
Please note: Corvus setting cannot be adjusted while logging.
