PARAMETER SETUP
Follow the procedure below to set the parameters such as flow rate deviation alarm, upper and lower limit
flow rate and event output delay time:
1. After introducing power to the MFC, press the [
DISP
] key twice (2X) to display the totalized flow
rate (‘
L
’ lamp lights).
2. Press the [
<
] key for three (3) seconds (the upper display indicates
‘
0.r
∩
9
’
[parameter setup
mode]).
3. Press either the [
∧

] or [
∨

] key until the desired setup item number is indicated.
4. Press the [
ENT
] key (the present setting value indicated on the lower display blinks).
5. Press either the [
∧
∧
∧
∧
] or [
∨
∨
∨
∨
] key to select the desired setting value (move to the digit to be changed
by pressing the [
<
] key). Press the [
ENT
] key to store the selected value. If the [
DISP
] key is
pressed prior to pressing the [
ENT
] key, the setting value remains at the previous value without
being updated.
6. Repeat steps 3, 4 and 5 for any setup item requiring programming. Once setup items are
completed, proceed to step 7.
7. Press the [
DISP
] key to return to the instantaneous flow rate display, the display shown after
introducing power.
Note: If no operation is performed for one (1) minute after entering the parameter setup mode, the
display automatically returns to the instantaneous flow rate display.
