To describe the operation procedure of the surface profile gauge as ELCOMETER 123 描述ELCOMETER 123表面粗糙度仪操作程序. This equipment MUST BE CALIBRATED BEFORE USE. The calibration procedure is as follows: 1.
Release the outer knurled ring by rotating the clamping screw anti-clockwise. 2.
Set the gauge to zero by placing it on to the glass sample provided. Then adjust the pointer. Turn the clamping screw clockwise to lock the ring. 把仪器放在所提供的玻璃样板上, 设好零位后,顺时针旋紧调节钮. 3.
Place the gauge on to the surface to be measured. The spring-loaded tip is projected into the valley and depth is indicated on the dial in microns or mils (thous), according to the scale. 把仪器放在待测表面上. 装有弹簧的尖端深入表面的凹谷里, 4.
To obtain a representative value of peak to valley height a number of (at least 10) readings should be taken on a given surface area and an average obtained. When evaluating the results, it must be remembered that the instrument reads from the maximum peak height under the foot. 至少在被测表面上读取十个读数来获得一个代表从谷峰到谷顶的平均值. The following equipment is used in calibration. If any problems occur, then the relevant calibration champion MUST be contacted immediately. Once the equipment is calibrated, the equipment is ready for use, as follows: 1.
Place the gauge on the test area. 2.
Press down the button on the top of the gauge. 3.
Observe/record reading. 4.
Repeat readings 4 - 5 times at various points on the test area. |
