Accessories 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.
