Altimeter TYPES?

[+Old Diego]

I've run into something that had me scratching my head. I can't find anything written on the altimeter types. Specifically, the number after them.

 

Example: Type=PRESSURE_ALTIMETER_2

 

I've seen PRESSURE_ALTIMETER_1 and PRESSURE_ALTIMETER_3. What are the differences and where should they be used?????

This is what I know, from an old file I have:

 

PRESSURE_ALTIMETER ---> usable for 4 digits altimeter (needle and digits)

PRESSURE_ALTIMETER_1 ---> needle only for 3 needles pressure altimeter (needle only)

PRESSURE_ALTIMETER_2 ---> needles and digits pressure altimeter

PRESSURE_ALTIMETER_3 ---> needle and digits pressure altimeter (1 needle + 3 digits)

Thanks, its becoming more clear now.
