3-3 Output mode inverting (window comparator
mode 4 only)
The output of any channel can be inverted.
Output mode inverting
S-0
: Non-inverted (normally open)
S- 1
: Inverted (normally closed)
Handling Precautions
• This function is disabled in any mode other
than window comparator mode 4.
3-4 Switch output response time setting
It is possible to set the amount of response time that
elapses (on-delay) until the switch output of a chan-
nel turns on.
Switch output response time setting
Sb- 1
: Disabled (3 ms or less)
Sb-3
: 100 ms or less
Sb-2
: 20 ms or less
Sb-4
: 1000 ms or less

Operation mode
●
Window comparator mode 1
L1 and L2 can be set to desired levels. If the flow rate
is increasing, SW output is not turned ON.
●
Window comparator mode 2
L1 is automatically set according to the
∆
L setting
and reference flow value (L1 = "reference flow
value" -
∆
L). If the flow value is increasing, output
is not turned ON.
●
Window comparator mode 3
L1 is automatically set according to the
∆
L setting
and reference flow value (L1 = "reference flow
value" -
∆
L).
Handling Precautions
• Do not input a trigger signal for memorizing
reference flow value frequently in window
comparator mode 2 or 3. Doing so might
cause the number of EEPROM erase-write
cycles to exceed the guaranteed amount.
●
Window comparator mode 4
L1 and L2 can be set to desired levels.
