*1. Capacity value when OMRON standard mirror surface target is measured at the measurement center distance as the average of 16,384 times
The value when the sensor controller ZW-5000T is connected
*2. Material setting for the OMRON standard mirror surface target: Error from an ideal straight line when measuring on mirror surface
*3. Capacity value defined by 1/e2 (13.5%) of the peak optical intensity of the measurement wavelength.
*4. When an extension fiber cable of 5 m or longer is connected, the setting rage of the measurement cycle (exposure time) changes. For details, refer to Setting Measurement Cycle in the ZW-8000/7000/5000 User's Manual (Cat. No. Z362).
