Frequently asked questions (FAQ) about the MINI technology
Question 1: Can I see the MINI measurement area ?
The MINI horizontal is a arrangement B device: The
illuminated are is the measured area. A darkened
room will demonstrate the illuminated area and
importance of placement and ” aiming ” of the MINI.
The MINI optical arrangement B (ASTM E1710) is
advantageous in the sense that it leads to less variation
of the measured value with small tilts of the
retroreectometer that are unavoidable in practical eld
measurements.
Question 2: Should I send my MINI back to factory for calibration ?
Each Easylux instrument by itself does not need re-calibration or special services unless damaged by external factors. To ensure reliable measurements, periodic checking or replacement of the instrument reference standard is recommended. Please contact www.easylux.com.br or your local distributor to know more about how to replace the calibration standards .
In case of MiniReflecto Horizontal the ceramic reference can be checked independently with a special Easylux Calibration Kit (sold separately).
Question 3: How many measurements can I do with new charged batteries ? Can I use any model of AA-size battery?
Full charged batteries will provide more than 8000 consecutive measurements. You should use AA-size rechargeable batteries with at least 2300 mAh. A fully charged brand new battery will make around 8000 consecutive measurements. If the number of measurements falls much below, it is time to replace it.
Question 4: How long is the charging time of the batteries ?
The multi-voltage power adapter and the vehicle power adapter will recharge the batteries within 8 hours. With 4 hours it is possible to get around 4000 consecutive measurements. For fast recharging, a third-party external AA battery charger can be used. Never leave the batteries uncharged for too long.
Question 5: Can I change the battery myself ?
Yes. The MINI uses 6 units of AA-size battery. Just remove the back battery cover to access the batteries.
Question 6: Should I calibrate the MINI every day?
Yes. It is recommended to calibrate the MINI at least once a day, after recharging the batteries, before starting to work, and after a significant temperature change.
Question 7: Does the sun affect the measurements?
No. The MINI is completely immune to solar light or any kind of external light (indoor lamps and road lamps).
Question 8: Can I check the retroreflectivity in wet conditions (ASTM E2177) or in continuous wetting ASTM E2832 RL-2 procedure ?
Yes. You can work without any attachments or modifications.
The MINI for road marking is an external beam instrument. It is completely immune to solar light or any kind of external light.
Question 9: Can the MINI records GPS coordinates?
It is stored for every measurement. The GPS synchronization could take from 3 to 10 minutes after power on. The MINI should be under open sky to get the GPS coordinates . The GPS is an optional item.
Question 10: Has it options to store user, place, and additional information about the place or material under test like stripe type, color, special notes, etc... ?
The MiniReflecto implements a LOG file system that can be used to organize your measurements.
When a new LOG is created, the user is asked for the following:
- LOG alias Name;
- Road Name;
- Starting milestone;
- Operator’s name;
- Direction (north, south, east, west);
- Material type (Paint, Thermoplastic, Epoxy, etc.);
- Special NOTE.
Question 11: Can the MINI for road markings work with high intensity materials over 2000 mcd.m−2 .lx−1 ?
Yes. The MINI horizontal can reach 4000 mcd.m−2 .lx−1
Question 12: What is the memory capacity?
All data are stored into a removable SDCARD. A standard 8GB can store over 1.000.000 measurements.
Question 13: Can MINI meets EN1436 and ASTM E1710 ? There is any independent test of compliance ?
The MINI is full compatible with EN1436 and ASTM E1710 standards. It was approved by an independent test laboratory StrAusZert (Germany). Test Certificate No. 0913 − 2014-04.
