F.S.: 28 mm measuring range of receiver
 1. Distance between emitter and receiver: 500 mm, measurement object at 250 mm from receiver. Glass ends of chamfer 0.1 mm or more can be detected in glass edge measurement mode. (at binary level 70%)
 2. Linearity is given to be a typical error with respect to an ideal straight line when the distance between the emitter and receiver is 100 mm and light is blocked at a distance of 50 mm from the receiver. (On the ZX-GT2840[][], the measurement object is measured at a distance of 20 mm from the receiver.)
 3. The amount of fluctuation (±3σ) in the analog output when the distance between the emitter and receiver is 100 mm and a ZX-GTC[][] is connected
 4. Change in the light cutoff value on one side when the distance between the emitter and receiver is 100 mm and the light is half-cutoff at a distance of 50 mm from the receiver (On the ZX-GT2840[][], the measurement object is measured at a distance of 20 mm from the receiver.)

Instruction Sheet

1. A simple average is used in IC lead pitch judgment mode or IC lead width judgment mode. The measurement cycle time can be calculated as follows: Specified measurement cycle time × (Number of samples to average + 1) + 1 ms max. In other measurement modes, a moving average is used. The first measurement cycle time can be calculated as follows: Specified measurement cycle time × (Number of samples to average + 1) + 1 ms max. The second and later measurement cycle times will be equal to the specified measurement cycle time.
 2. The response time in the high-speed mode (FAST) for the IC lead pitch and IC lead width judgment modes is 1 ms.
 3. Current/voltage can be switched using the switch provided on the rear of the Controller.
 4. Can be set by the analog output scaling function.
 5. The error (ERR) state is displayed when all HIGH/PASS/LOW outputs turn OFF.
 6. Normally, wire the sync output wire directly to the emitter’s sync input wire and run the Controller in the standard mode. On an NPN type Controller, use an NPN type emitter, and on a PNP type Controller, use a PNP type emitter. Wiring of the sync wires is not required when the Controller is run in the high-speed mode.
 (Note, however, that the Controller becomes more susceptible to the influence of ambient light in this case.)
 7. The value is 175 mA max. (including receiver) when current output is set.
