Mu-Checker
EV-16A Counter SERIES 519 — 6-channel, No-display Type
• Up to six probes can be connected to one unit. Up to ten counters can be connected to one personal computer using the RS Link function to enable the configuration of a multi-point measurement system comprising a maximum of 60 gages.
• I/O outputs for RS-232C, BCD, tolerance judgment and segment output are available. • Maximum, minimum and runout measurement between channels (in the same unit) is possible in addition to normal measurement on individual channels.
519-355 EV-16A
SYSTEM CONFIGURATION Mitutoyo probes, EV-16A counters and D-EV display units combined with commercial controllers and personal computers enable construction of a powerful, multi-channel system that can be built to meet the needs of almost any measurement application.
Main features • External control (Zero-set, Preset etc.) • Direction switching • Error messaging • Tolerance judgment output • Each data output (RS-232C, BCD, segment) • Peak measurement (maximum value, minimum value, runout) and arithmetic operation (addition, average, maximum value, minimum value, maximum width) between axes
