^1 The models with “A” at the end of the name have additional functions such as display averaging. Use the head with “A” at the end of the name. When connecting conventional heads without “A” at the end, the FD-MH operates in the same way as the conventional models. ^2 Only connect to the back of DL-RS1 (A) or FD-MA. ^3 The rated flow range indicates recommended operating range. ^4 Flow under the zero cut flow will be displayed as 0 L/min. ^5 Convert the F.S. (full scale) listed in the table according to the rated flow range. ^6 Maximum 20 mA for alarm output. When the total number of extension units is between 6 and 10, set each output current to 10 mA or less.
