The Ametek VTI Instruments VM2710A is a 6.5-digit multimeter engineered for high-performance automated test equipment and data acquisition systems. This VMIP™-family instrument mounts as a C-size VXIbus card, delivering over 2000 readings/second across the backplane—eliminating speed constraints imposed by onboard memory limits. Built-in limit checking and threshold-triggered VXIbus outputs reduce controller overhead.
