12. ELIMINATING FLUCTUATION AROUND “0”
A measured value less than the preset cutout value can be forcibly cut to 0 (figures below). This parameter is called low-
end cutout and the value is called low-end cutout value. Enable the low-end cutout first and set the low-end cutout value
within the range of 000 to 999. Figures 1 and 2 show difference between low-end cutout ON and absolute value low-end
cutout ON. The low-end cutout is effective to eliminate slippage or fluctuation of the display values near zero.

SETTING RANGE
Set the low-end cutout value for the three lowest digits of the display scaling value within the range of 000 to 999.
The default value is 000.

Absolute value Low-end cutout
The display value less than the low-end cutout value is
forcibly cut to 0.
The display value of which the absolute value is less
than the low-end cutout value is forcibly cut to 0.
NOTE
• Set the display scaling starting 0 when the low-end cutout is set to ON. Otherwise with the display scaling ±1000 and
the low-end cutout value 50, for example, the indication with the scaling value -1000 to 49 will be cut to 0.
• When the display scaling is set to negative to positive range, set the low-end cutout to absolute value low-end cutout
ON.
• The low-end cutout setting affects the DC output when the analog output function mode is set to “proportional to the
display value”. Refer to 7. SETTING ANALOG OUTPUT for details.
