Prologue
General
Thank you for purchasing the Q-Test. At Crowcon we recognise the need for quick and simple gas
test solutions which are suitable for the challenges of on-site and off-site use.
Q-Test provides a quick and simple in-eld gas test and calibration solution. Providing off-site testing
for remote locations where power is not always available or practical. Simple to use and easy to
repeat, Q-Test reduces set-up, training requirements and space needed.
Flexibility
Q-Test manages speedy and smart bumps as well as calibration. Q-Test can also be easily mounted
via din rail mounts on a wall or inside a vehicle to give a gas test solution for any application.
The charging option also gives a permanent home to detectors mounted in vehicles and is easily
powered via a standard in-vehicle power socket or multiregional power supply.
Remote Workers
When in the eld, Q-Test provides conned space workers with repeatable gas testing solutions that
maintain detector integrity and safety. When working in conjunction with +ve Safety™ eet managers
can quickly and easily tell when site requirements have not been adhered to.
Economic
Repeatable test solutions that, through recommended gas use instructions, can offer over 200
speedy bumps from a 34l cylinder and over 330 speedy bumps from a 56l cylinder.

The Q-Test can be mounted on a standard DIN rail type EN 50022 À or screwed to a suitable at
surface through the 3 holes Áin the module’s main body (see below).
The recommended length of DIN rail if a Q-Test is to be mounted on its own, is 150mm.
If the Q-Test is to be used in conjunction with a cylinder holder, the recommend length of DIN rail
required is 250mm.
The recommended length of DIN rail if a Powered Q-Test is to be mounted on its own, is 275mm
(this is supplied with the powered Q-Test).
If the Powered Q-Test is to be used in conjunction with a cylinder holder, the recommend length of
DIN rail required is 350mm.
Mount the DIN rail to the wall (at side against the wall), allowing space on at least one side to slide
the Q-Test on.
The cylinder holder is available to mount on the DIN rail or direct to the wall.
i Ensure that when the Q-Test is mounted, the Gas-Pro screen and operator button will be
accessible (see Figure 7 on page 12).
