1.2 Measurement 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.

2.13 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,
