+ve Safety™
+ve Safety™ (Positive Safety) provides
positive conrmation of detector status prior
to deployment in the eld or on return from
site. The front mount tri-colour LED gives
the Safety Manager or Supervisor unrivalled
visibility of the status of the Operator’s
detector.
Charging
• To charge, insert the charger connected into the socket at the back of
the Gas-Pro.
• The display will show the battery lling and RED LED’s will ash red
until the battery is full, when they will ash green.
Gas Testing
Crowcon recommends regular gas tests (also known as bump tests) to
conrm sensor operation. A number of exible and simple solutions are
available:
Q-Test Quick and simple in-led gas test and calibration solution.
I-Test Intelligent wall or desk mount, powered data management
solution.
S-Test Service and maintenance solution for up to 5 detectors.
If congured to do so, test and calibration can also be completed manually
by using the non-pumped ow plate and following prompts on the screen. If
a test should fail or calibration is due and the Gas-Pro has been manually
zeroed in the last 15 minutes a calibration can also be completed.
See the Gas-Pro User and Operator manual for details.

OPERATION
Switching On/Off
• In clean air turn on the Gas-Pro by holding down the operator button
for 3 audible blips. The Gas-Pro will warm up, going through a series of
automatic processes.
• To turn off, press and hold the operator button. During the 4 second
countdown hold the button down until the countdown has nished.
Quick View
• A momentary press of the operator button allows the user to see the gas
type and unit, battery level, user and +ve Safety™ status.
Alarms
• Gas-Pro offers audible, visual and vibrate alarms as standard.
• Each gas has 2 instantaneous alarms and toxics also have TWA alarms.
• When in alarm the display backlight will change from green to red and
highlight the gas in alarm.
• When the Gas-Pro warns of a low battery, the sounder will emit an audible
double blip every 5 seconds and the +ve Safety™ LED will go red. This
means the battery has at least 30 minutes of battery life remaining. After 30
minutes the Gas-Pro will enter full alarm state and the battery icon will ash
empty as shut down is imminent.
Backlight
• The backlight is congurable but set as standard to come on at the press
of the operator button or during alarm.
Pump
• If the internal pump option has been chosen, the pump is activated by
attaching the pumped ow plate.
• Ensure the gasket is clean and undamaged prior to placement.
• The pump test will activate every time the ow plate is attached the user
will be prompted to cover the inlet to ensure a tight seal. Gas-Pro will
indicate a pass or fail, if failed the ow plate should be removed, checked
and reapplied.
USER MENU
• Access the user menu by double clicking the operator button, then
scroll through the menu using single clicks. Once the correct function
is highlighted, double click to choose.
Zero
• During start-up the operator has the option to perform an autozero, or
leave the countdown if an autozero is not required/possible.
• A manual zero can be performed at any time following start up and is
needed less than 15 minutes prior to running a manual calibration.
Time Weighted Average (TWA)
• This function allows the 8 hour TWA to be reviewed.
Pre-Entry Check (PEC)
• This function is intended for sampling air of unknown quality before
gaining access to it (e.g. going under ground through a manhole
cover) thereby avoiding unnecessary exposure.
Peak Review
• This function allows the highest level of each gas detected to be
reviewed during the last 8 hours, 12 hours or since turned on.
