GM 480A not the same model in 4801 no digital display it will match GM610A anyway thanks for yr effort.
I have an image of the module i will try to post
Thanks for your reply and feedback.!
OK as per the shared file.. GM4801 is little bit old fashion way...
Span zero would be for calibration...
Do you have an idea about C/N selector..
I will have a look on web and ask around my professional network if anybody have such manual..
Thanks for your reply...
Your rite its old modelnits installed on the 6B machine
C /N. For calibration and normal mode selection as i know the put the calibration mode sw to C and inject the gas and adjust the span as per reference gas
. During power up sometimes control module will fail also don't know how to change the alarm setting. Just want confirm.for power up and power off is there any special concern like Bead current adjust or something .
Thanks once again .
