The Digimar 817 CLM height measuring instrument offers three distinct 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 a measurement. Combined with a Teach-In Mode, these features can reduce inspection time for a mini series consisting of only a few test pieces.

The instrument has an air bearing system that facilitates smooth movement for positioning. An 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 precisely tracks the measuring head. The instrument offers a range of measurement functions in either 1-D or optional 2-D.
