• Analog output when specifying the scaling setting
The analog output range is assigned based on the pre-scaling display value setting range
(between S1-BEF and S2-BEF).
Concerning the analog output minimum and maximum values, the analog output minimum
value is output for the smaller of the post-scaling display values (S1-AFT/S2-AFT), and the
analog output maximum value is output for the larger of these values.
Example) To set the analog output in the range of –5 V to 5 V and display a value from
45 mm to 55 mm when using the ZX2-LD50(L) at a distance of 45 mm to 55 mm
from the sensor:
(1) Select –5…5V as the analog output setting.
(2) Set the BEF value and assign the analog output range based
on the range of measured values.
Set the AFT value and assign the display value based on the
measured value.
• S1-BEF: –5 (mm)
• S1-AFT: 55 (mm)
• S2-BEF: 5 (mm)
• S2-AFT: 45 (mm)

• Threshold value when specifying the scaling setting
Even if scaling is executed, the threshold does not change from the setting before execution
of scaling. (For example, the HIGH threshold stays at 5 if it was 5 before scaling is executed.)
