In case of choosing COUNT or RANGE
COUNT : displays totalized flow counts (8 digits) without a unit.
RANGE : displays the range number (1 to 4)

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
*5
(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 m
3
/min 50%
LF610 measured value 10.5 m
3
/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%
