PG34Tolerance SettingTolerance limits can be set in various display units for automatically indicating if a measurement falls within those limits.Open Collector OutputAn external load, such as a relay or a logic circuit, can be driven from the collector output of an internal transistor which is itself controlled by a Tolerance Judgement result, etc.Relay outputContact signal that outputs the open/closed status.Digimatic CodeA communication protocol for connecting the output of measuring tools with various Mitutoyo data processing units. This allows output connection to a Digimatic Mini Processor DP-1VR for performing various statistical calculations and creating histograms, etc.BCD OutputA system for outputting data in binary-coded decimal notation.RS-232C OutputA serial communication interface in which data can be transmitted bi-directionally under the EIA Standards.For the transmission procedure, refer to the specications of each measuring instrument.RS Link Function Multi-point measurement can be performed by connecting multiple EH or EV counters with RS Link cables.RS Link for EH CounterIt is possible to connect a maximum of 10 counter units and handle up to 20 channels of multi-point measurement at a time.For this connection use a dedicated RS Link cable No.02ADD950 (0.5m), No.936937 (1m) or No.965014 (2m). (The total length of RS Link cables permitted for the entire system is up to 10m.)Personal computerIN RS-232C connector First counter RS-232C cable *01 Gage number020304…… Last counterOUTIN RS-232C connectorOUTIN RS-232C connectorOUTPersonal computerINRS-232C connectorUnit 2RS-232C cable01Gage number060712………………OUTINOUTINOUTExternal display unit 1External display unit 2INOUTUnit 1RS-232C connectorRS Link for EV CounterIt is possible to connect a maximum of 10* counter units and handle up to 60 channels of multi-point measurement at a time.For this connection use a dedicated RS Link cable No.02ADD950 (0.5m), No.936937 (1m) or No.965014 (2m). (The total length of RS Link cables permitted for the entire system is up to 10m.)* The maximum number of counter units that can be connected is limited to 6 (six) if an EH counter is included in the chain.*Only the Mitutoyo software “SENSORPAK” can be used when a USB cable is connected.
