  • Page 8 3 months. 1. Set-up PRIOR TO USE Before use, the Gas-Pro should always be checked for any signs of physical damage. Gas-Pro uses a Lithium Ion (Li-ion) battery pack and should arrive with sufficient charge to be used straight out the box. However, if this is the first time of use, you may need to charge the battery to attain the full operating time (see Charging).
  • Page 9 Charging should only take place in non-hazardous (safe) areas. To charge, sim- ply plug the cable ① into the charging socket ② on the Gas-Pro and turn on the mains supply (see Figure 2 below). If a charging cradle or vehicle cradle is being used, ensure the Gas-Pro fits firmly on to the power connector.
  • Page 10 (see Pump test). There are 3 types of flow plate: one for a Gas-Pro with internal pump, one for a Gas-Pro with no pump and a non-magnetic version for PC calibration or for ma- nual sampling.
  • Page 11 TURN ON In ‘clean air’, turn on the Gas-Pro by holding down the operator button for 3 audi- ble blips. The Gas-Pro will warm up, going through a series of automatic proces- ses as follows: Firstly a test screen pattern will be generated.
  • Page 12 Pro it will be shown next in the turn on sequence. If the Gas-Pro is configured for regular Gas Testing (Bump Test), the date of the last Gas Test will also be shown (for more information on Gas Testing, see Gas testing and calibration).
  • Page 13 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.
  • Page 14 When the test has finished, the pump will either pass or fail If the pump test takes place during start-up and the Gas-Pro passes, the pump will remain on and the start-up process will continue as normal. If the test is...
  • Page 15 Figure 14: Gas-Pro indicators In the alarm state, Gas-Pro will vibrate, its sounder ① will emit a rapid tone, the alarm LEDs ② will flash red and blue, the +ve Safety™ indicator ③ will be off in alarm, the LCD display ④ will also be red and highlight the gas in alarm.
  • Page 16 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.
  • Page 17 2.5.2 INSTANTANEOUS ALARM The Gas-Pro will go into alarm immediately if the level of any of the gases it is configured to detect become outside acceptable limits. A minimum and maxi- mum acceptable level is set for oxygen, for most other gases the Gas-Pro will go into alarm state 1 or 2 according to which level has been exceeded.
  • Page 18 (see below), Gas-Pro will retain the STEL, TWA and peak gas values when powered back on. If Gas-Pro is switched off for more than 15 minutes but less than 8hrs, and the TWA Resume function is selected (see below), Gas-Pro will retain the TWA and peak gas values when powered back on but the STEL values will be cleared.
  • Page 19 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.
  • Page 20 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 dam- age has occurred.
  • Page 21 Please refer to Crowcon application note PID-AN-001 for further details on main- tenance and cleaning of the PID sensor. GAS-PRO FUNCTIONS The following can be selected from the Gas-Pro user menu: Home screen Manual zero Time weighted average (TWA) review...
  • Page 22 P. 22/47 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.
  • Page 23 Before you start the Pre-entry check, ensure you are ready to start the test (i.e. any flow plate, sampling probe or hand aspirator are fitted to the Gas-Pro as re- quired). From the home screen, double click the operator button to enter the menu se- lection screen.
  • Page 24 TWA calculations. The Gas-Pro will remain in the peak stage for a maximum of 5 minutes. When accessing the Peak Review screen the peak displayed will be the gas peak (trough for O2) seen in the selected time period;...

  • Page 26 SHUT DOWN To turn the Gas-Pro off, press and hold the operator button. A 4 second count- down will start. Hold the button down until the countdown has finished and the Gas-Pro will shut down.
  • Page 27 The data log records gas levels for all sensors and has capacity for 45,000 logs (125hrs @10 sec intervals). Threshold levels can be set using Portables Pro, ex- tending log capabilities. The data log interval is set as part of the Gas-Pro config- uration and can be adjusted using Portables Pro.

Figure 17: Tank Check Mode selection Upon entry to Tank Check Mode, the device will display a confirmation message to inform that alarms are disabled.
  • Page 29 SENSITRON M07995 Manual (EN) A Halma Company GAS-PRO P. 29/47 2.9.1 DUAL-RANGE OPERATION Tank Check Mode allows the Flammable IR sensor to display flammable gas readings in both %LEL and %VOL ranges. When the flammable gas level is below 95%LEL, the measurement is displayed in %LEL range.
  • Page 30 Health and Safety regulations should be adhered to, and a number of flexible and simple solutions are available. Gas-Pro offers two types of bump test. A speedy bump test which is a gas test to the first alarm level and smart bump test, a gas test to a specified level of test gas.
  • Page 31 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).
