Note 1) For digital flow switch unit switching function (Fixed SI unit [V or L/min] will be set for switch types without the unit switching function.)
Note 2) Set to hysteresis mode at time of shipment from the factory. Can be changed to window comparator mode by using the push buttons.
Note 3) This is the response when the value is set to 90% on a 0 to 100% step input.
Note 4) When the flow rate display function is selected, repeatability and display accuracy should be identical to the graph in the manufacturer's catalog.
Note 5) Auto-shift function is turned OFF at the time of shipment from the factory. Use after turning auto-shift on by using the push buttons.
Note 6) Please consult with the manufacturer support center regarding wiring.
Note 7) Products with small scratches, smears or variations in display color and brightness, etc. that does not affect the performance will be verified as conforming products.

Settable Range and Voltage Input Range

The settable range is the range that can be set in the switch.
The inputtable range is the range that satisfies the switch specifications (accuracy, linearity, etc.)
It is possible to set a value outside of the inputtable range if it is within the settable range; however, the specification is not guaranteed.

Settable range and voltage input range

The settable range is the flow range that can be set in the switch.
The rated flow range is the flow rate range that satisfies the switch specifications (accuracy, linearity, etc.)
It is possible to set a value outside of the rated flow range if it is within the settable range; however, the specification is not guaranteed.

Function Details

Output operation

The output can be selected from the following: Output (Hysteresis mode and window comparator mode) corresponding to receiving voltage. At the time of shipment from the factory, it is set to hysteresis mode, reverse output.

Displayed values

The monitor receives the output voltage of the connected sensor and displays the received voltage. The unit is [V] and the voltage is displayed at 0.01 V intervals.
However, voltages below 0.70 V are displayed as “LLL” and voltages of 5.1 V or above are displayed as “HHH”. Since the voltage is displayed on the monitor, it does not rely on the sensor range.

Auto-preset function

This is a function that calculates the set value automatically. When a predetermined operation is conducted while the sensor is connected, the set value is calculated and decided automatically by changing the flow rate. (Fine adjustment is also possible.)

Selection of power-saving mode

Power-saving mode can be selected. With this function shifts, if no buttons are pressed for 30 seconds, it shifts to power-saving mode. At the time of shipment from the factory, the product is set to normal mode (power-saving mode off). (When power-saving mode is active, the decimal point flashes.)

Setting of secret code

The user can select whether a secret code must be entered to release the key lock. At the time of shipment from the factory, it is set to not require a secret code.

Peak/bottom value indication

The maximum (minimum) voltage is detected and updated from when the power supply is turned on. In peak (bottom) value indication mode, this maximum (minimum) value is displayed.

Keylock function

Prevents operation errors such as accidentally changing setting values.

Display mode

Select whether to display the voltage or the instantaneous flow rate. The displayed flow rate value is for the standard condition (ANR) of 20°C, 1 αtm and 65% R.H.
