The Digimar 817 CLM offers three ways to initiate measurement. In addition to normal keypad initiation, a quick mode feature allows the measurement cycle to be initiated by pushing the carriage in the direction of the object to be measured. Also, two speed keys on the base allow the operator to comfortably move the measuring carriage to the desired position and start measuring. Combined with a teach-in mode, these features can reduce inspection time for a mini series consisting of only a few test pieces. The gage has an air bearing system that facilitates smooth movement for positioning, and its optical incremental measuring system with a double reader head is insensitive to dirt. A dynamic probing system provides high repeatability, and a stainless steel guide column with precision ball bearings tracks the measuring head.
