5-525-6-11. Setting low flow cutoffThis function is used to set the low flow cutoff value. When the flow rate reaches the enteredvalue, the analog output is cut off and latched to 4 mA (display flow rate of 0%) to avoid errorsdue to flow pulsation in range value close to zero.Also, for reverse flow rate the output is latched to 4 mA (display flow rate of 0%) The lowerlimit of the low flow cutoff setting is determined by the velocity range.1. If the velocity range exceeds 3 m/s, the lower limit value is 1%.2. If the flow speed range is 3 m/s or less, the lower limit value will cut the flow speed of 0.03m/s or less flow the rate.Example: If the flow speed range is set as 2 m/s, the lower limit of the low flow cutoffvalue is 1.5%. (= 0.03/2 = 0.015 = 1.5%)Setting range: 1 to 10%Default: Depends on the velocity range.Set low flow cut in accordance with the following procedure:Step Procedure Screen1 Enter ENGINEERING MODE in accordance with theentry into ENGINEERING MODE (see section 5-5-10. on page 5-33). Then press the or key todisplay the screen at right.12.3 %# LOW-FLOW CUT02 %2 Press the key.The cursor then moves to the position of the low flowcut value.12.3 %# LOW-FLOW CUT02 %3 Using the or key, change the value to a desiredvalue to be set. 12.3 %# LOW-FLOW CUT05 %4 Press the key to move the cursor to the positionunder #.Press the MODE key to return to theMEASUREMENT MODE and to save data.12.3 %# LOW-FLOW CUT05 %CAUTIONYou have only ten minutes to return to MEASURING MODE to save the new value beforethe system resets it to the previously saved value.
