Digital Gauge Frequently Asked Questions
Question number FAQ-0086
Explanation of spindle operation for models DG-825, DG-925, DG-525, and DG525H.
Spindle Tracking Speed
The maximum response speed of the spindle is shown in the table below.
Model | Maximum response speed (at 20°C) |
|---|---|
| DG-825 | 1m/s |
| DG-925 | 500mm/s |
| DG-525・525H | 300mm/s |
If you operate at a speed higher than this, it may malfunction. If an 'E' (error) mark appears on the display, please turn off the power using the power switch and then perform the measurement again. Additionally, depending on the measurement object, it is advisable to bring the spindle close within 1mm before dropping it.
<2> About spindle lift
When measuring, directly moving the spindle up and down with bare hands may result in an error of several micrometers due to the adhesion of oil, dust, etc. Please use the included finger lift or gently pinch the measuring part to move it.
<3> About the reference point of the spindle
The stopping point of the spindle, when not in contact with the reference plane, does not become a fixed point due to the adoption of a damper. Please take the reference point at the position where the spindle is pushed in (arbitrary).
