MA6 Portable Gloss Meter is a portable gloss measuring instrument designed and manufactured according to international standard ISO 2813 and Chinese national standards GB/T13891, GB9754, GB7706, GB8807.
Instructions
★Start self-calibration and self-diagnosis
Self-calibration: Automatically adjust the measurement parameters of the instrument to be consistent , making the operation of the instrument convenient and fast. The self-calibration process window is displayed as follows: (example)
After the self-calibration is completed, the measured value is displayed, and the measurement can be taken out of the host!
Self-diagnosis: Timely discover system errors, improper operation , and prompt the operator to make corrections to avoid measurement errors; if the self-calibration fails, the display window will have the following prompts:
Users are requested to sort and process in the following order:
1. Power off - power on, and perform self-calibration and self-diagnosis again.
2. Check whether the surface of the working board is clean. If there is any stain, please wipe it gently with a mirror cloth and absolute ethanol.
3. Check whether the main unit is fully buckled into the base, only when it is in place can it pass the self-calibration.
4. Check whether the calibration value setting of the instrument is consistent with the display value of the working board. If they are consistent, please repeat step 2.
★Measurement
Remove the base, place the measuring port of the instrument on the part to be tested, and the instrument will immediately display the gloss value of the place.
Tip: Recalibrate the instrument after using it for more than 45 minutes to ensure accurate data!
Note: Users should pay attention to the difference between instrument sensitivity and instability. A sensitive gloss meter should have higher sensitivity to the difference of the measured surface gloss, but when the instrument is in a fixed position, the instrument should not have a large jump, a large jump indicates that the instrument is unstable, It belongs to the problem of instrument quality.
Verification instructions
★Check
Calibration requires professional self-calibration steps, and then take out the instrument and place it on the white working board correctly. The difference between the displayed value of the instrument and the calibration of the white working board is not more than 1 gloss unit, otherwise the calibration must be repeated.
Tips: Calibration is the self-check of the instrument by the user when there is doubt about the measured value, and it does not need to be performed before each measurement.
★Calibration value adjustment
When the actual gloss value of the working board changes, the calibration value needs to be adjusted to ensure the accuracy of the measurement data.
To adjust the calibration value, you must press and hold "∧" after turning on the machine normally. At this time, the window will display as shown in the figure (1-1). After 3 seconds, the original calibration value will be displayed. Release the button , and use "∧(+) ∨( -)” button to adjust the new calibration value. The machine will automatically shut down if there is no operation for 6 seconds after the setting is completed.
Buckle the machine into the base and turn it on again, the instrument will automatically perform self-calibration according to the new calibration value.
Tips: The calibration value must be adjusted only when the actual gloss value of the working board changes or a new working board is replaced.
