Recommended Basic Settings (as Guide Values)
The following values are guide values for typical workshop measurements. Depending on the standard specification, surface, expected values, and parameters, it may be useful to adjust Lt/Lc/N.
| Setting | Guide Value | What is it good for? |
|---|---|---|
| Traverse Length Lt | 4.8 mm or 15.0 mm | Good standard tradeoff: fast & close to standards (depending on surface) |
| Cutoff Lc | Standard (0.8 mm for Lt 4.8 mm / 2.5 mm for Lt 15 mm) | Standard-compliant filtering as a basis; reduces misinterpretations |
| Number of Individual Sampling Lengths N | 5 | Typical standard according to ISO/JIS/ASME (robust against outliers) |
| Measuring Speed | 1.0 mm/s (fast) or 0.5 mm/s (stable) | 0.5 mm/s if you prioritize maximum reproducibility |
| Filter Ls | Automatic | Device selects based on traverse length – good practical default |
Important: With "Automatic", the traverse length can be set based on standards depending on RSm/Rz – ideal when different levels of roughness are measured.
Pro Workflow (7 Steps) – How to Measure Reproducibly
- Remove transport lock and keep it safe (re-use it for return transport).
- Insert drive unit correctly (let it click into place cleanly – no "half" locks).
- Set measurement conditions: Lt/Lc/N, pre-travel/over-travel, measuring speed – save as Quick&Easy if recurring.
- Calibrate the probe with integrated standard: read the Rz target value, place the standard so the entire traverse length lies within the defined roughness, then start the calibration process.
- Start measurement (green start button) and check the result/profile (plausibility, outliers).
- Document: Generate the report directly in the device as a PDF or save data (e.g., CSV/PDF) – depending on your QA process.
- After the measurement: Tilt the device to the side when setting it down without a case to protect the probe tip.
Troubleshooting: 4 Typical Problems (and Fast Fixes)
1) Calibration returns "implausible" / Correction value too large
- Check measurement setup: Is the standard positioned correctly? Is the entire traverse length in the roughness field? Is the probe tip vertical?
- Check if the nominal/target value was entered correctly (read Rz from the standard and enter it exactly).
- If a usable result is repeatedly not achieved: The probe might be defective – have it checked.
2) Values "jump" / Poor repeatability
- Reduce measuring speed to 0.5 mm/s (more stable feed, fewer dynamic effects).
- Check traverse length/cutoff: Adjust Lt/Lc for your surface if necessary (standard is a good starting point).
- Clean the probe (brush) and keep the surface free of oil/particles.
3) Battery drains quickly / Device not charging as expected
- Only use the supplied power adapter + USB cable (protection against damage/warranty).
- As a guide: Full charge via power adapter ~3 h; via normal PC USB port longer (typically 6–7 h).
- If capacity drops significantly: Battery replacement only by qualified personnel (observe specifications).
4) Device/results seem "wrong" after transport
- For shipping: Remove drive unit, attach transport lock, store everything in the case.
- After transport: Perform calibration and a plausibility measurement.
- Check connectors/locking points (is the drive unit cleanly engaged?).
Maintenance & Care (5 Points for Long-Term Accuracy)
- Clean the housing if necessary with a soft, lint-free cloth (slightly moistened) – no aggressive/alkaline agents.
- Clean the probe if necessary with a soft hair brush – do not let liquid enter the device.
- Store accessories in the transport case; protect from dust, high humidity, and direct sunlight.
- Check the integrated standard regularly; replace after approx. 350 calibrations (guide value).
- If measurement errors are suspected: Verify accuracy by calibrating with the integrated or a suitable standard.
FAQ (Practical)
1) Which traverse length should I use first?
Start practically with Lt 4.8 mm (fast) or Lt 15 mm (more "statistics" over the distance). If you are unsure, use the Automatic setting (standard-based according to RSm/Rz) and save the parameters as Quick&Easy.
2) What is the benefit of "Cutoff = Standard"?
The standard cutoff is the safe default for standard-compliant filtering. It logically links Lc to the traverse length and prevents roughness/waviness from being "accidentally" mixed.
3) How often do I need to calibrate?
For reproducible QA, regular calibration is recommended (e.g., daily/per shift) or whenever the setup, probe, or environment has changed. The integrated standard is intended for this – but it does wear out (observe guide values).
4) Can I save measurement results directly as a PDF?
Yes – depending on the setup, reports and data can be saved as files (including PDF/CSV). This is ideal for QA because you bring measurement and documentation together at the workstation.
5) What are good "starting parameters" for coating/production checks?
Ra and Rz are frequently used as a basis. Additionally, RSm can help if the structure/groove spacing is relevant. Important: Always interpret parameters in the context of your drawing/standard and the functional surface.
Conclusion
The MarSurf M 310 is a powerful "workshop tool" for mobile roughness measurement: with Quick&Easy programs, standard-compliant filter logic, and an integrated standard for controlled calibration. If you consistently standardize Lt/Lc/N and keep your workflow clean, you will quickly get reproducible results – exactly what QA and production need in everyday life.
