Data Indicating User - set current output
Pulse output with a user - set counting rate
Previous status Is retained (excluding pulse output).
Instaneous flow rates and flow velocity (no totalization).
(1) In case of the zero adjustment (Menu No.EI),Zero offset is automatically cleared to Zero.
(2) Calculate the zero offset value with the foilwing equation:
Zero offset value (U) = ((Actual flow rate) - (LF600 measured value))
Measured condition Flow rate 91 In measured span
Actual flow rate obtained
from other instrument 10.0 m3/min 5091
LF600 measured value 10.5 m3/min 52.591
Zero offset - -2.591
If zero offset is set to -2.5X, LF600 will output 50.091 flow rate instead of 52.591
