I-Test Overview
I-Test is suitable for small and large eet users alike and offers simple gas monitor bump testing and
calibration, including full data management.
I-Test versions are available for both Gas-Pro and T4.
I-Test can quickly and simply undertake testing and store data either locally to the I-Test or allow
download to a PC or USB memory stick, including download and storage of gas monitor log les.
I-Test provides data management allowing easy reporting of bump test and calibration results across
the eet.
I-Test can also offer simple updating of gas monitor details such as alarm levels with updates being
managed within the eet during regular bump tests.
Using minimal gas and managing sequencing the I-Test ensures sensors are gassed correctly every time.
Suitability
I-Test is suitable for testing and calibrating Gas-Pro and T4 units tted with one or more of the following
sensors: Oxygen, Carbon Monoxide, Hydrogen Sulphide, Carbon Dioxide IR or Methane Pellistor.
I-Test will be functional with Gas-Pro units congured with rmware versions 1V09 & 2V06 onwards. The
rmware version of Gas-Pro can be seen as part of the start up screens when the monitor is powered up.
I-Test is functional with rmware versions of T4 from 1V01 upwards.
I-Test Functional Overview
I-Test offers the following main functions and features for the testing, calibration and management of
gas monitors.
Speedy bump
A speedy bump will test the monitor sensors to the rst alarm level.
Gas is presented across/over the sensors for a designated time (dependent on sensor gas type)
during which alarm level one should be activated. This will be deemed a pass if the monitor goes into
alarm or a failure if the monitor does not go into alarm.

Smart bump
A smart bump will test that the gas monitor responds correctly to a specied level of test gas.
Gas is passed over/across the sensors and a predicted response is expected within a time window
dependant on the sensor response time.
The test is passed if the gas level indicated by the monitor is within pre-specied tolerance limits
within this time window.
Calibration
I-Test can be congured to undertake the routine service calibration of a gas monitor. In this instance
a calibration would be completed without a bump test being required.
I-Test is suitable for routine service calibration of monitors.
If a new sensor has been tted to the monitor then Portables-Pro should be used to calibrate the
monitor not I-Test, otherwise incorrect calibration may occur.
Calibration after bump fail
If any sensor fails a speedy bump or smart bump, I-Test can be congured to perform a ‘calibration
after bump fail, immediately after the bump test failure.
Gas Monitor Field Conguration
During normal operation, whilst performing gas testing, I-Test can be congured to change aspects
of the inserted gas monitor conguration, such as sensor alarm levels as well as other aspects of
conguration.
Gas Monitor Log Download
During normal operation I-Test can be congured to download either event logs and/or data logs
from the monitor under test. These log les are stored locally and can be extracted either via PC or
USB ash drive.
Data Management & Reporting
I-Test in conjunction with its PC Application, I-Test Manager, can be utilised for full data management
of the bump test and calibration data.
I-Test Manager allows the user to specify exception reports to quickly identify instruments, for
example, that have not been bump tested or failed bump test. I-Test Manager will also allow a user
to upload and view monitor log les from the I-Test. Bump test and calibration reports can also be
created, printed and stored.

Gas Inlets/Exhaust
I-Test is available with 2 inlet ports and 1 exhaust port. One inlet is reserved for purge gas (fresh air),
and the other inlet is the test gas inlet.
USB Input/Outputs
I-Test offers the ability to upload its conguration settings either via USB connection to a PC or via a
USB Flash Drive inserted into a connector on the side of the I-Test.
DC Input/Battery Backup
I-test is capable of operating from a DC power supply but also able to operate for a short period of
time on an internal backup batter pack should the DC supply fail.
Keypad interface
I-Test offers keypad interfaces that will allow a user to change many of the conguration settings
without the need to connect a PC or insert a USB Flash Drive.
