Alarm displayMeasuring unit disconnected, Excess speed, Maximum display amount exceeded, Power failure, Error in stored data
ResetResettable by key switch
PresetIt is possible to store/call 3 kinds of numbers.
Reference point detectionThe reference point of the measuring unit can be detected, and the datum point can be relocated (during connection of measuring unit with a reference point)
Data storageThe value displayed before the power was turned off and setting values are stored
Linear error compensationA fixed compensation is applied to the measuring unit's count value. Compensation amount Standard: ±600 um/m (Expanded: ±1000 um/m)
Segmented error compensationThe movement range of the measuring unit with a reference point can be divided into a maximum of 32 sections, and error compensation is performed for each of these sections. Compensation amount: ±600 um (at each section)
ScalingScaling factor:0.100000 ~ 9.999999
Program
  • Machining coordinates can be programmed (number of program steps: 850 max.)
  • 1. Manual programming by key switch
  • 2. Automatic programming by playback
  • 3. Mirror image during program execution
  • 4. A canned cycle (bolt hole, line hole, simple R cutting) can be inserted in the program
Angle displayCan be displayed as an angle value when the Digiruler is pasted to the arc surface, and the diameter and Digiruler resolution are entered
