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.

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.
