DG-B (Necessary to use the conversion adaptor which is sold separately.)
Measuring unit input Standard: 0.1 µm, 0.5 µm, 1 µm, 5 µm, 10 µm, 1 s, 10 s, 1 min, 10 min
resolution Expanded: 100 µm, 50 µm, 25 µm, 20 µm, 2 µm, 0.05 µm and 1 degree can be added.
Display resolution
Measuring unit input resolution or higher and diameter display (except for angle display)
Input signal A/B quadrature signal, Z signal (Conforms to EIA-422.)
Minimum input phase difference
100 ns
Quantization error ±1 count
Alarm display
Measuring unit disconnected, Excess speed, Maximum display amount exceeded,
Power failure, Error in stored data
Reset Resettable by key switch or remote reset.
Preset It is possible to store/call 3 kinds of numbers.
Reference point detection
The 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 storage The value displayed before the power was turned off and setting values are stored
Linear error compensation
A fixed compensation is applied to the measuring unit’s count value.
Compensation amount Standard: ±600 µm/m (Expanded: ±1000 µm/m)
Segmented error
The movement range of the measuring unit with a reference point can be divided into a
compensation
maximum of 32 sections, and error compensation is performed for each of these sections.
Compensation amount: ±600 µm (at each section)
Scaling Scaling factor: 0.100000 to 9.999999
Machining coordinates can be programmed (number of program steps: 850 max.)
1. Manual programming by key switch
Program
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.
(LH71A only)
Angle display
Can be displayed as an angle value when the Digiruler is pasted to the arc surface,
and the diameter and Digiruler resolution are entered
Sleep
The display is turned off when no operations are made for a preset time.
(The time can be set.)
Power supply DC 12 V Rating 0.75 A Max. 1 A
AC 100 to 240 V ±10% (When using AC adaptor which is sold separately.)
Power consumption Max. 32 VA (connected at AC power supply)
