- Page 22 Operation 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 Gas testing become outside acceptable limits. A minimum and maximum 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 23 Alarm can be turned off only when gas has returned to acceptable levels has returned to acceptable levels Set-up While in alarm, the Gas-Pro will continue to record levels of all the gases being monitored.

- Page 24 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 must have a gas test to ensure no lasting damage has occurred.
- Page 25 Certain operations will only take place if the Gas-Pro has been recently zeroed . For example, if Warranty 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 26 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. The Gas-Pro (and any sampling probe) should be in a clean air when the PEC starts and finishes so the TWA accumulation should be insignificant.
