3.5.1 Stylus Position
First, check the stylus position.
When measuring in surface, usually don’t need adjust stylus position.
When using the Height Lifting Pillar to measure the work-piece surface, you need to adjust the vertical
height of the instrument to determine the pointer near zero. After the pickup is exposed to the measured
surface, the measurement can begin.
3.5.2 Calibration
If the difference between the measured value and the specimen value is greater than the scope of
equipment requirements, or user requirements are more accurate, you can use that value of the
calibration function to correct measurement results.
The calibration steps are as follows
：
1
Enter the Calibration Menu
Under the main interface, long press setting / menu button to enter the main menu, press up (down)
arrow to select calibration, press the enter key to set correct values, as follows
：
2
Setting Correct Values
Press upper (lower) arrow to select the required range, press the left (right) arrow to adjust settings.
According to the evaluation, revise the inaccuracy, input the corresponding range then exit. Test
several times and make a fine tuning until proper.
Notes:
The calibration value is according to the corresponding operating, each range can be calibrated
independently from each other. Calibration results are stored in the instrument's memory and
will not lose after shutdown.
3.5.3 Calibration Cautions
1
If the actual measured value exceeds ± 10% of the value of the calibration model, indication
calibration should be used in accordance with the percentage of actual bias calibration, the
calibration range should not exceed ± 20%.
2
Under normal circumstances, the instruments have been rigorously tested in the factory. The
showing error is much less than ± 10%. Frequently use calibration function is not recommended at
this time.
3
If you want to set the showing calibration value to 00, it will restore to the factory setting.
3.6 Start Measurement
1
Start
After finishing above operations, in the main unit, press start key to start measuring.
2
Measuring
Measurement after the beginning of the first interface, at this time, probe is collecting data.
