Integration function
※ To make setting about integration, refer to 13. Applied Operating Procedure.
① Maximum integrated flow rate
Maximum 12-digit integration measurement is possible.
For details, refer to 11. Basic Operation of the Indicator.
② Integration timing
An instantaneous flow rate value is added every one second.
③ Power failure measure
The integrated flow rate is stored/held every one minute and as soon as the power is
recovered, integration will restart. When this happens, the integrated flow rate for one
minute maximum from the storage to the power failure is lost.

Upper/lower limit flow rate alarm allowable range (OK judgment) function
※ To use this function, refer to 13. Applied Operating Procedure.
① When the instantaneous flow rate value is above the upper limit alarm value or below
the lower limit alarm value, the ALM LED lights and the alarm output is turned on.
② When the instantaneous flow rate value is between the lower limit alarm value and the
upper limit alarm value, the OK LED lights.

Zero adjust and auto zero functions
① Zero adjust function
Pressing the yellow [ZERO] adjust switch on the side face of the main unit corrects the
zero point.
② Auto zero function
When the operation mode is the fully closed state or when the set flow rate is 0 and the
instantaneous flow rate value is 2% of the full scale or less, the zero point is
automatically corrected.
