In the next step, you should carry out the settings at the zero point (menu 3) and end point (menu 4), as well as the decimal point (menu 2). The displayed value of the ASM 400 should correspond to the respective measuring value of the transmitter. -
Page 9: Menu Operation
ASM 400 4.2 Menu operation The menu system is a closed system allowing you to scroll both forward and backward through the individual set-up menus to navigate to the desired setting item. All settings are permanently stored in an EEPROM and therefore available again even after disconnecting from the supply voltage. -
