5-6-4 : Setting flow rate range
Set the flow rate range. The lower limit of the range is ZERO. The upper limit, which
is the value when the output reaches 100%, is entered here along with the selection
of engineering and time units. The range has an upper limit value of 5 m/s in flow
velocity when it is calculated at the upper stage of the display. It has a lower limit
value of 1 m/s.
Set the flow rate range so that the regular flow rate is greater than or equal to 50% of
the flow rate range.
Pressing the MODE key automatically deletes unnecessary zeros, if any, from the
flow rate range.
Example: 07.069
g
7.0690 (Unnecessary zero is deleted.)
Setting range:
Flow rate range: 0 to 0.0001, 0 to 99999.
Units of flow rate:
Unit of SI volume flow rate: m
3
, 1, cm
3
Unit of SI mass flow rate: t, kg, g
Unit of non-SI volume flow rate: mG, G, kG, B, mIG, IG, kIG
Unit of SI mass flow rate: lb
Unit of time: d, h, min., s
Set the flow rate range in accordance with the following procedure:
