  Why isn't my Gas-Pro charging?

The Gas-Pro is most likely charging, if the Gas-Pro has gone into deep discharge the display will not show the instrument charging symbol until it has been charging for 10+ minutes and the button has been pressed after this time. You will then see the charging symbol and the red LED flash.

Fixed Detectors

  If I have a flameproof fixed detector (Ex) can I make it "intrinsically safe" (IS) by using a zener barrier or galvanic isolator?

No, a flameproof detector "safety protection" cannot be changed by using a zener barrier or galvanic isolator of any sort. It can only be used as a flameproof device.
