Problems related to gas detector


While calibration the zero calibration is ok, but the span calibration is faulty, if you look at the above display you can see a number. I have changed the PCB, sensor and also the cartridge but it is still faulty

Every gas detector will have the same issue when you don’t give sufficient pressure as how much it requires during calibration for span calibration.

There may have more chance of toxic cylinder low pressure or going to empty.

Or check the loop integrity well and try to reset from ICS panorma were ever accessible for soft key (accept/reset )inhibition as well as F&G panel hard key accept reset. Then go for calibration
