Gas library 113
8 Gas library
The operating software of the Protec P3000 contains a list of about 100 gas equiva-
lents which are relevant to the refrigerating industry. These gas equivalents are
stored in a ROM (read only memory) and from the list contained in this memory
gases and trigger levels may be selected through the corresponding sub-menus. The
data contained in the ROM can not be changed. In addition, the program provides 40
unoccupied memory locations (user library EEPROM memory). Here the user may
save the data of gases the parameters of which he has defined himself (see User
Library). He may also select any gases defined earlier. The library of the Protec
P3000 contains the following gases by default:
