1-3 Peak hold and bottom hold

The peak or bottom flow rate can be displayed.

Handling Precautions

• The displayed channel can be changed during hold.

• If the power is turned OFF, the peak hold or

bottom hold is cancelled.

• Peak hold and bottom hold cannot be done at

the same time.

• When the indication hold function is activated,

the output hold function is also activated at the
same time.

1-4 Flow rate display moving average setting

The flow rate moving average shown on the 7-seg-
ment LED can be set.

2 Basic settings

2-1 Flow sensor selection

The desired flow sensor can be set for each channel.

Flow sensor settings

SE 1

: MCS100A100 (-3 to +3L/min)

SE2

: MCS100A104 (0 to 3L/min)

SE3

: MCS100A108 (-500 to +500mL/min)

SE4

: MCS100A112 (0 to 500mL/min)

SE5

: MCS100A120 (0 to 10L/min)

2-2 Operation mode selection

The desired operation mode can be set for each channel.

Operation mode settings

C0 1

: Window comparator mode 1

C02

: Window comparator mode 2

C03

: Window comparator mode 3

C04

: Window comparator mode 4

2-3 Threshold settings (L1 (

L)/L2)

The desired threshold flow rate can be set for each channel.

Threshold flow rate settings

: 1ch_L1/

L

3 1

: 3ch_L1/

L

12

: 1ch_L2

: 2ch_L1/

L

4 1

: 4ch_L1/

L

22

: 2ch_L2

42

: 4ch_L2

Handling Precautions

• If the threshold flow rate is set such that L1 

L2, the switch output does not turn ON.

• “L1 

L2” may also come about when 

L is

set in window comparator mode 2 or 3, due to
reading of the reference value, with the result
that the switch output does not turn ON.

2-4 Hysteresis settings

The desired hysteresis can be set for each channel.

Hysteresis settings

H S 1

: Ch. 1

H S3

: Ch. 3

H S2

: Ch. 2

H S4

: Ch. 4

Handling Precautions

• To prevent chattering, set the hysteresis value

to 2 or more.

3 Advanced settings

3-1 Reading the reference flow rate (window

comparator mode 2 or 3)

When window comparator mode 2 or 3 is used, the
reference flow rate may be read.

3-2 Zero point adjustment (zero reset)

The zero point can be adjusted for each channel.
