FAQs
What is the total measuring range of this indicator?
The MW400-01 has a total measuring range of 1.0mm.
Does this indicator meet industrial standards?
Yes, it is manufactured in accordance with DIN 878 standards.
Can I replace the measuring contact point?
Yes, the contact point is typically threaded and can be replaced if worn or if a different shape is required for specific geometries.
What is the resolution of this instrument?
The resolution is 0.001mm, making it suitable for very high-precision tasks.
Is the dial face large enough for easy reading?
The unit features a 58mm diameter dial, which is standard size and provides excellent legibility for most shop applications.
Should I oil the internal gears?
No, do not oil the internal mechanism. Professional calibration services should be used for internal maintenance.
Troubleshooting
Needle movement feels sticky or jerky
Gently clean the plunger shaft with a dry, lint-free cloth; ensure no oil or coolant has gummed up the track.
Measurements appear inconsistent
Check that the mounting clamp is fully tightened and the base is stable on a clean, flat surface.
Bezel is loose and shifts during use
Tighten the stop screw located on the side of the bezel to lock your zero position firmly.
Pros and Cons
Pros
- High-precision 0.001mm resolution for critical tolerances
- Complies with recognized DIN 878 standards
- Durable tungsten carbide contact point resists wear
- Shockproof design improves longevity in busy shops
- Easy-to-adjust bezel for quick zeroing
Cons
- Limited measurement range of 1.0mm requires frequent resetting for larger parts
- Requires professional calibration to maintain accuracy
- More delicate than standard digital indicators
Setup, Compatibility & Care
To begin using the MW400-01, mount the indicator stem to a standard gauge holder using a secure clamp. Ensure the contact point is perpendicular to the surface being measured to minimize cosine error. For care, keep the indicator free from metallic dust, oil, and coolant, as these contaminants can infiltrate the plunger mechanism. Never lubricate the plunger shaft, as this attracts debris that causes sticking. Store the instrument in its protective case when not in use to avoid accidental drops or damage to the contact tip. Regular verification against a master calibration block is recommended to ensure the tool remains within its ±0.004mm tolerance.
