Note: At the time of shipping, the write protection function is enabled except for address and baud
rate. Once the user completes the register value change, the write protection will be automatically
enabled once again to prevent incidental data loss.

low rate 0x003A ~ 0x003B
Flow rate = [Value (0x003A)*65536 + value (ox003B)]/1000
e.g.
: for a flow rate of 20.340 SLPM, the user will read “0” from register
3A and “20340” from register 0x003B, therefore
Current flow rate = (0*65536+20340)/1000 = 20.340
