*) Sensor to be connected is selected during initial setting. When CO2 is selected as applicable fluid, the maximum side will become 1/2.
*2) When the connected sensor 10 L/min and the minimum setting unit 0.01 L/min are selected, the display upper limit will become "10.50 L/min."
When the connected sensor 100 L/min and the minimum setting unit 0.1 L/min are selected, the display upper limit will become "105.0 L/min."
When shipped from factory, the connected sensor is set to 10 L/min and the minimum setting unit is set to 0.1 L/min.
*3) For digital flow switch unit switching function (Fixed SI unit [L/min or L] will be set for switch types without the unit switching function.)
*4) Accumulated flow rate value is cleared when the power supply is turned OFF and returns to zero. It is possible to select a function to hold the accumulated value so that it is not cleared. (It is possible to select whether to keep the accumulated value at 2-minute interval or 5-minute interval.) When the 5-minute interval is selected, the number of rewrites is limited to 1 million times (5 minutes × 1 million times = 5 million minutes = 9.5 years when energized for 24 hours), which is the lifespan of the memory element (electronic component), calculate the service lifespan from the operating conditions and use within the service lifespan when using the holding function. For digital flow switch unit switching function (Fixed SI unit [L/min or L] will be set for switch types without the unit switching function.)
*5) Set to hysteresis mode at the time of shipment from the factory. Can be changed to window comparator mode by using the push buttons.
*6) When shipped from factory, integrated value external reset function is set. Auto-shift and Auto-shift zero function can be selected by push button operation.
*7) For wiring, refer to the instruction manual.
*8) Products with small scratches, smears or variations in display color and brightness, etc., that do not affect the performance will be verified as conforming products.
