E300 Series LED Displays

BN2 LCD Digital Readout


E300 series of EZ TECH DRO Counters offer multiple different types of LED display options for both 2- and 3-axis milling and lathe machines.

Item Number Description
E320M LED Display for 2-Axis Milling
E330M LED Display for 3-Axis Milling
E320L LED Display for 2-Axis Lathe



  • Preset
    To enter values into the DRO and save them in its memory so they can be recalled when necessary.
  • Direct mm/inch conversion via keyboard
  • Absolute, incremental signals
  • Resolution of up to 0.1 microns
  • Linear axis compensation
    The error caused by the axis on a machine may be compensated by parameter.
  • Calculator function
    To perform mathematical and trigonometric operations and preset any axis with the result of the calculation or use the feedback reading (position values) to carry out mathematical calculations.
  • 299 SMD reference points
    For part homing and/or tool settings.
  • Software travel limits
    These limits do not cancel the hardware limits set by the limit switches on the machine, but they give the operator the choice to set other travel limits between the main ones.
  • Multi-point compensation
    A multi-point error is an interpretation of an error between two points of the travel; that error may be compensated with the DRO. Up to 200 points along the travel.
