-10 to +10 V or 4 to 20 mA
Measurement
range
5% to 100% of rated setting
Measurement
time
1 to 1000 ms
Measurement
item
Mean value/maximum (peak)
Measurement
accuracy
± 3% of full scale (excluding sensor error)
Displacement
*1
Measurement
range
The measurement range changes depending on the
SENSOR STEP setting. The measurement range of
displacement is ± (SENSOR STEP setting x 30000)
µm.
(Ex.) When the SENSOR STEP setting is 1 µm:
±30.000 mm
When the SENSOR STEP setting is 10 µm:
±300.00 mm
Measurement
item
Starts measurement at the start of current flow and
measures the displacement at the end of delay time.
Measurement
accuracy
±30.000 mm range: ±15 µm (sensor with 1 µm or less
resolution)
±300.00 mm range: ±150 µm (sensor with 1.1 µm or
more resolution)
