Range type Description
1 : SINGLE Single range
2 : 4F-0R Unidirectional flw , automatic selection of multiple ranges
3 : 2F-2R Bidirectional flows , automatic selestion of multiple ranges
4 : EXT 2F-0R Unidirectional flows , multiple ranges selected by exterminal single
5 : EXT 2F-2R Bidirectional flows , multiple ranges selected by exterminal single

(1) In case of the zero adjustment (Menu No.F1),Zero offset is automatically cleared to Zero. (2) Calculate the zero offset value with the follwing equation: Zero offset value (%) = {(Actual flow rate) - (LF610 measured value)} (Sample)
Measured condition Flow rate % in measured span
Actual flow rate obtained from other instrument
10.0 m3/min 50%
LF610 measured value 10.5 m3/min 52.5%
Zero offset
-
-2.5%
If zero offset is set to -2.5% , LF610 will output 50.0% flow rate instead of 52.5%
