2Measurement principle
When measuring roughness of part surface, the pickup is placed on
the surface of the part and
then tracing the surface at constant rate. The pickup acquires the
surface roughness by the sharp stylus in pickup. The roughness
causes displacement of pickup which results in change of inductive
value of induction coils thus generate analogue signal which is in
proportion to surface roughness at output end of phase-sensitive
rectifier. This signal enters data collection system after amplification
and level conversion. After that, those collected data are processed
with digital filtering and parameter calculation by DSP chip and the
measuring result can be read on LCD, printed through printer and
communicated with PC.

13 Parameter calibration
Before measuring, the instrument usually required calibration on
standard calibration block. The instrument is configured with a standard
calibration block, before measurement, instruments should test on the
block. Under normal circumstances, when the difference between the
measured value and the block value is in the acceptable range, the
measurement value is valid, can be measured directly.
If the measured value and the block value which difference is greater
than a accuracy error range of the instrument, or the user require high
accuracy, can be used to correct the indication calibration function and
improve measurement accuracy. The value of the calibration procedure
is as shown.
Illustration is based on a model calibrated 1.63μm steps to calibrate the
model for the actual calibration of the nominal value of the set value.
1. Under normal circumstances, the instrument in the factory have been
rigorously tested, showing error is much less than ± 10%, in this case,
the user is not showing the value of the calibration frequently used
functions.
2. After setting the calibration value, you must press the START key for
a full measurement, instrument calibration to be valid.
3. New parameters after calibration must be carried out once a
complete measurement and press the Save&Exit key is stored in the
instrument.
4. Press "Exit"key to return the menu without saving calibration results.

4Groove Sensor
5Small hole Sensor
The groove sensor is the standard sensor of the roughness meter, and
its demension are as follows:
Small hole sensor can measure the plane, inclined plane, cone surface,
inner hole and other surface roughness.
Minimum measurable hole diameter:Ф5mm
The use of small hole sensors must be installed on the measuring
stand for measurement.
6Extra small hole sensor
Using Extra small hole sensor, the inner surfaces of holes with radius
more than 2.5mm can be measured. Refer to the following Figure for
detailed dimension.
Extra small hole sensor operation method
The skid of the extra small hole sensor is behind the stylus. When it
contacts the workpiece, the pickup position is first high and then low.
The use of extra small hole sensors must be installed on the measuring
stand for measurement.
With deep groove sensor, it is possible to measure groove with width
wider than 3mm and depth deeper than 10mm, or the surface
roughness of step with height less than 10mm, Also can used to
measure the planar, cylindrical used with platform. please see figure for
detailed dimension.
7Deep Groove Sensor
