IN USE
+ve Safety™
+ve Safety™ (Positive Safety) provides
positive confi rmation of detector status prior
to deployment in the fi 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 fi lling and RED LED’s will fl ash red
until the battery is full, when they will fl ash green.
Gas Testing
Crowcon recommends regular gas tests (also known as bump tests) to
confi rm sensor operation. A number of fl exible and simple solutions are
available:
Q-Test Quick and simple in-fi 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 confi gured to do so, test and calibration can also be completed manually
by using the non-pumped fl 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 fi 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.
The operator has the option to Resume TWA alarm monitoring after
powering-off (software version 1V25 and higher).
• 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 fl ash
empty as shut down is imminent.
Backlight
• The backlight is confi gurable but set as standard to come on at the press
of the operator button or during alarm.
Pump
Please refer to the Safety Information in section 2.4.2 of the Gas-Pro User &
Operator Manual before using pumped/sampling mode.
• If the internal pump option has been chosen, the pump is activated by
attaching the pumped fl ow plate.
• Ensure the gasket is clean and undamaged prior to placement.
• The pump test will activate every time the fl 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 fl 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.
Flammable Correction factor. Only available for
pellistors.
• This option selects the fl ammable gas correction factor to be used for
fl ammable (pellistor) sensors with respect to the base calibration of
methane.
