Specication

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.

Troubleshooting

Specication

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.

This section details how to operate I-Test to perform the desired testing after I-Test has been fully
congured via I-Test Manager (see page 25) or via I-Test Front panel Keypad (see page 90).

Ensure I-Test is installed correctly and that the test gas cylinder is attached as detailed on page 12.

Before operating the I-Test it must be congured via I-Test Manager PC Application and

i

must then be disconnected from the PC USB connection. If I-Test is not disconnected
from the PC it will not operate.

Before a test can be undertaken ensure the I-Test display screen is showing the home

i

screen. If the home screen is not shown the congured test will not be initiated.

Ensure the test gas cylinder connected to the inlet, has the same gas mix and

i

concentration as congured in the I-Test (see page 40 or page 94).

When manufactured I-Test is congured with a default gas cylinder and a default expiry

i

date. This expiry date must be changed to that of the actual cylinder to be attached or
I-Test will not function correctly as it will report that the cylinder has expired.

To ensure accurate bump testing and calibration the purge inlet MUST be connected to

i

fresh air.

When I-Test is initially powered it will perform a purge cycle for approximately 30

i

seconds, before I-Test can be used.

2.1 Gas Monitor Testing Overview

X I-Test Manager needs to be congured for the type of I-Test purchased, either ATEX region or

UL region compatible. This is due to the calculation I-Test will undertake to convert a volume

of ammable gas (%VOL) to a lower explosive limit value LEL, each region has a different

Once a cylinder has been dened, Inlet Conguration will allow the cylinder to be assigned to a gas
inlet on I-Test. This assumes a specic cylinder of gas will then be physically connected to that inlet

and therefore allows the user to enter the actual concentration of gas, the lot number and the expiry
date of the cylinder.

3.4.3 Actions

This section allows the user to congure the operation or sequence of operations that will be undertaken

automatically when a gas monitor is inserted into the I-Test and the door closed. This sequence may

include (amongst others) speedy bump, smart bump, calibration and download of log les.

3.4.4 Field Conguration

During normal operation I-Test can be congured to change aspects of the gas monitor conguration,

this can occur as a stand alone activity or as part of a bump test or calibration. I-Test can change

gas monitor sensor alarm levels, logging interval and condence strategy as well as other aspects of
conguration.

3.4.5 Reporting/Data Management

I-Test Manager offers the user a number of ways to manage the data collected by I-Test in normal

use. I-Test Manger can be used to view gas monitor log les uploaded during gas testing.

Bump test and calibration reports can then be generated as appropriate to the tests I-Test was

congured to undertake.

In addition, exception reporting can be utilised to allow the user to identify gas monitors that, for

example, have passed or failed a bump test or calibration in the last ‘x’ days, or are due calibration.

3.7 Initial Conguration of I-Test

This section details how to congure and setup I-Test for initial use. This section steps through each
stage required to fully congure I-Test prior to saving this conguration.

3.7.1 Manage cylinders

Prior to conguration of I-Test and assigning a cylinder to the inlet of I-Test, the cylinder prole must
rst be dened.

I-Test can congure a number of cylinder proles for potential connection to a gas inlet. These
proles are detailed in Appendix A.

I-Test Manager will prevent any combination of cylinder being created other than those listed in
Appendix A.

To create or alter a cylinder prole, proceed as follows:

X Select Manage cylinders from the Home page. The Manage cylinders dialogue box will be

displayed (see below).

X To edit an existing prole, click on the cylinder prole in the Dened Cylinders list so that it is

highlighted and then click Edit.

Alter the following elds as required:

Cylinder type: To create a new cylinder prole select the required cylinder type from the drop

down list.Cylinder options are tri, quad or quin.

Suitability: Select the use(s) for which this cylinder is suitable by clicking on the relevant

tick boxes.
Suitability options are speedy bump, smart bump , calibration and cross
calibration.
When calibration is selected speedy bump and smart bump are automatically
selected.
When cross calibration is selected calibration, speedy bump and smart bump
are automatically selected.

Note: Smart bump functionality is only applicable to Gas-Pro, T4 will only

undertake a speedy bump test.

Crowcon recommend calibration standard gases are used for calibration functions to

i

ensure accurate calibration of the gas monitor under test.

Two calibration options enable the ammable sensor in the gas monitor to be

tested with either target gas or, if required, the C5H12, C3H8 and C4H10 sensors
can be tested with CH4 when the cross calibration option is selected.

Unless the cross calibration option is selected gas monitors must only be bump tested or

i

calibrated with target gas.

Calibration: This option should be selected if ammable sensors in all gas monitors to be

tested by I-Test are to be calibrated with target gas only.

For example if ammable sensors in all the monitors are CH4 and the cylinder

to be used for testing contains CH4, then this option should be selected.

or calibrated by an I-Test are not all congured with the same ammable gas

sensor or if the target gas is not available for monitors containing C5H12, C3H8,
C4H10 sensors.

For example if the eet contains a mixture of monitors with CH4 and C3H8

sensors both requiring test by I-Test, then the cross calibration option should
be selected when conguring the cylinder.
This will allow both the CH4 and C3H8 gas monitors to undergo the desired
bump or calibration test in the same I-Test unit.

If the cross calibration option is selected, cylinders must be congured with CH4 as the

i

ammable gas. The concentration of CH4 must be 1.2% volume for ATEX/IECEx monitors
and 1.5% volume for UL monitors.

For a list of cylinders available from Crowcon please refer to Section 8.

The gas cylinder for cross calibration must have a tolerance no greater than 5%.
If the Cross Calibration option is selected this will also allow gas monitors to be
bump tested with non target gas in the same manner as described above for
calibration.

Note: T4 must only be calibrated with a cylinder containing CH4, the

cross calibration option is not applicable for T4 and will not operate in a T4

congured I-Test.

Gases: Click on a gas in the Gases list and then make a selection from the Gas drop

down list, and enter the standard gas value in the Standard Value eld.
Dependant upon cylinder type selected the gas options are CH4, C5H12, C3H8,
C4H10, CO, H2S, CO2 & O2 (see Appendix A: Allowable Cylinder Proles).
Dependant upon the suitability option chosen, I-Test Manager will restrict the
gas value entered to ensure the gas value is appropriate for the Suitability
selected.

When dening the standard value of the ammable gas selected, the gas value
must be entered in units of %volume. The saved value will be converted to
%LEL for internal use in I-Test.
Note: T4 must only be bump tested and calibrated with a cylinder containing

CH4. A T4 congured I-Test will not perform the congured test if any other
cylinder is connected to I-Test.

X When the alterations have been made, click Update Gas. This will update the entry in the Gases list.

X Repeat this process for each gas to be dened in the cylinder prole.

changes will be made to the gas monitor.

The ‘Allow conguration tick box in the ‘Actions’ page must also be

selected to perform a eld conguration.

Apply Changes On: This allows the user to determine the date from which it is required to update

the conguration on the gas monitor.
If a date in the future is chosen I-Test will continue to operate as normal until

that date, at that point I-Test will then update the conguration each time the

gas monitor is inserted.

Enter the required start date for the gas monitor conguration by changing
each value in the eld or clicking the calendar button to the right of the eld.

Condence

Strategy: Condence strategy is how the gas monitor indicates to the user that it is

functioning normally.

If it is required to change the condence strategy setting on the gas monitor
activate the Condence Strategy tick box and from the drop down box select

one of the following options:

Off: No indications.
Sounder: The gas monitor sounder beeps at preset intervals.
LED: The gas monitor LED’s ash at preset intervals.
Sounder + LED: The gas monitor sounder beeps and the condence LED’s

ash at preset intervals.

T4 Conguration has two further options

Positive Safety: The gas monitor will activate positive safety (+ve safety)

functionality which is an easy indication of operating status of T4 indicated by a
front mounted LED. Please refer to the T4 User & Operator Manual for further
details.

Positive Safety + sounder: The gas monitor will activate positive safety

functionality plus the addition of the sounder when the positive safety LED is
illuminated.

Interval: This eld sets the time interval in seconds for the Condence Strategy

indications. Select the required interval from a minimum interval of 5 seconds

to a maximum interval of 60 seconds.

with regard to the built in ‘Clean air’ zero function.
If it is required to change the Action on Startup setting on the gas monitor
activate the Action on Startup tick box and from the drop down box select one
of the following options:
No action: No ‘Clean air’ zero action at startup.

Conrm zero: This setting allows the ‘Clean air’ zero to be carried out at the

user’s discretion.

Always zero: This setting means a ‘Clean air’ zero will always be carried out

at startup.

Logging Interval: This eld determines the interval at which the gas monitor will record gas

readings to its internal log le.

If it is required to change the logging interval activate the logging interval
tick box and set the required time interval in seconds. Minimum interval 1 of

second and maximum interval of 32400 seconds between log readings.

Calibration Due
Increment: If a gas monitor is congured to undertake either a Bump Test Fail Calibration

or a Stand alone Calibration, and the calibration is successful, the calibration
due date will be incremented within the gas monitor.

The increment interval (in days) is precongured within the gas monitor at
factory, typically 30 days.

It is possible to change this increment by uploading a new conguration le to

the gas monitor.

Activate the Calibration Due Increment tick box and set the required interval in

days (minimum 1, maximum 720) between calibrating the monitor

Once I-Test has been congured to apply a monitor eld conguration le, it will continue

i

to do this to each and every monitor inserted into I-Test. If it is required to stop the

conguration update it is necessary to deselect the ‘Apply Changes On’ tick box and save
this conguration to I-Test.

Exception reports provide the ability to review and co-ordinate data with regard to the management

of a eet of gas monitors.

Once the relevant data has been collected from I-Test and imported into I-Test Manager it is possible
to produce a selection of exception reports with various criteria.

It is for example possible to create an exception report that will list all gas monitors that have passed
a bump test, or produce a report that lists all gas monitors that have failed a calibration. There are
many variants of exception report that can be produced, this section details this process.

3.12.1 Creating an Exception Report

Exception reports can only be created for gas monitors that have been inserted into an I-Test and
then (dependant upon requirements of exception report) had I-Test Action log and gas monitor event
log, extracted from I-Test and imported to I-Test Manager.
