Thank you for purchasing the new Gas-Pro. At Crowcon we recognise the need for reliable and robust personal monitors which are sized to be worn and simple to use. Gas-Pro is a portable monitor capable of detecting up to 5 gases in a compact and wearable design featuring an optional internal pump. Focused on users and fleet managers alike, Gas-Pro offers application focused solutions giving greater operating time and reduced set up time.
‘Contacts’ section of the manual (see page 58). • Ensure maintenance, service and calibration is carried out in accordance with the procedures in the manual and only by trained personnel. • Gas-Pro must not be charged or have communication to the device, at ambient temperatures outside of the temperature range 0°C to 40°C. • Only connect to Gas-Pro in a safe area for charging or communications. • Charging cable assemblies, whilst nominally providing a voltage of 6.5V, must not exceed a voltage of 9.1V as this may impair intrinsic safety and invalidate safety certification (Um=9.1V). • Communication cable assemblies, whilst nominally operating at a voltage of 3.0V TTL, must not exceed a voltage of 9.1V as this may impair intrinsic safety and invalidate safety certification (Um=9.1V).

Should the unit be deep discharged, the charging indication will not be shown until the unit has been charging for 1 hour and the operator button has been pressed. When on and charging a warning will advise the user to turn the Gas-Pro off after 12 hours or remove from charge.
PC software Accessories Specifications Appendices Warranty shooting 1.5 Quick view Even when the detector is off, users can display details about the configuration of the Gas-Pro by momentarily pressing the operator button for one audible blip. The LED to the left of the display will flash red once and the Quick view screen shown in Figure 6 below will be displayed for 10 seconds.

The Autozero Confirm screen will be displayed next. Figure 11: Autozero confirm screen An Autozero should not be performed unless the Gas-Pro is in clean air. Press the operator button to enter the Autozero mode, otherwise the countdown will progress and will not perform a zero. If the operator button is not pressed the countdown will complete and this function will be skipped.

I f the Gas-Pro is configured for Bump functionality, the Bump/Pump prompt will be displayed if a flow plate is attached and a gas bump test is due or the Gas-Pro is placed in a Q-Test module during normal use (see Bump/Pump functionality on page 35). Prior to fitting, the flow plate’s gasket should be checked for any damage. The pump test ensures accurate sealing as well as monitoring pump performance.
Gas-Pro can either be worn or used with hoses and probes to sample from spaces prior to entry. The pump capacity in the Gas-Pro is 0.5l/m and will draw a sample of gas from 30m within 80 seconds. Please note the expected losses for some gases below.
0% VOL 0% VOL 20 s 0% VOL 79 s If Gas-Pro is operated in pumped mode in combination with an exhaust pipe, a set of bellows should be used inline (e.g. flow plate, 2cm maximum tube, bellows, 3000cm maximum tube). Gas-Pro also has a specific pre-entry mode (see Section 2.6.5). 2.4.3 Manual sampling If the internal pump option has not been chosen the hand aspirator may be used for pre-entry checks and remote sampling.

TWA and peak gas values when powered back on but the STEL values will be cleared. If Gas-Pro is switched off for more than 8hrs the TWA Resume function will not be available in the startup sequence and Gas-Pro will clear the TWA, STEL and peak gas values when powered back on.
Figure 15: Simply click the operator button. If Gas-Pro is now being used by a new operator and the TWA Resume function is not required do not click the operator button and allow countdown to expire. This will reset the STEL, TWA and peak values back to zero. * Patent pending – UK Patent Application Number 1501699.1 2.5.4 Accepting and clearing alarms...

2.5.5.5 Pellistor saver mode While in saver mode and the subsequent stabilise time, the gas level displayed on the LCD screen will indicate over range. If the alarm is so severe as to cause a sensor over-range the Gas-Pro should have a gas test to ensure no lasting damage has occurred. Pellistor sensors can suffer degradation if powered...
When this icon is selected, the Home screen will be displayed. 2.6.3 Manual zero This function should only be carried out in ‘clean air’ and allows the Gas-Pro to be zeroed at any time. Certain operations will only take place if the Gas-Pro has been recently zeroed . For example, if configured to do so, Gas-Pro will progress to a calibration after failing a gas test if the unit has been manually zeroed in the last 15 minutes.

Specifications Appendices Warranty shooting 2.8.3 Bump/Pump functionality If the Gas-Pro is configured for Bump/Pump functionality, then by placing the Gas-Pro in a Q-Test module or attaching a flow plate (with the Gas-Pro home screen displayed), the Bump/Pump screen will be displayed (see Figure 16 below). Figure 16: Bump/Pump screen Click the operator button to highlight for Pump or for Bump testing and then double click to select (see...
Flow Plate Gas-Pro can also be tested simply by using the flow plate and applying gas If Gas-Pro is operated in pumped mode in combination with an exhaust pipe, a set of bellows should be used inline (e.g. flow plate, 2cm maximum tube, bellows, 3000cm maximum tube). EN60079-29 part 1 has been harmonised under the ATEX directive (2014/34/EU). Therefore to comply with the ATEX directive, portable apparatus sensing flammable gases should have a functional check with gas before each day of use. Other testing regimes may be employed depending on local circumstances.
Figure 20: Gas test due screen Gas-Pro will not inform the user of a need for a gas test until the interval period from the last successful bump has expired. However on applying a magnetised flow plate, or placing Gas-Pro into the Q-Test the user will be given the option to complete a gas test (or proceed to pumped operation). If the sensors are grouped into the ‘Daily’ group, the Gas-Pro will...

PID sensor 3.2.3 Calibration after bump fail If any channel fails speedy bump or smart bump then Gas-Pro can be configured (via Portables Pro) to perform a ‘calibration after bump fail’ immediately after the test failure. Calibration should only be performed with appropriately accurate gas.
(see Section 6.2, PC interface cable), this data can be collected and viewed. 6.2 PC interface cable Portables Pro allows the download and viewing of data and event logs from the Gas-Pro using an interface cable via the USB socket on a laptop or desktop computer. Please see Portables Pro instructions for details.
