Page 4: Introduction
1 Introduction 1.1 Scope of applications Ultrasonic Thickness Gauge measuring with ultrasonic wave is applicable for measuring the thickness of any material in which ultrasonic wave can be transmitted and reflected back from the other face. The gauge can provide quick and accurate measurement to various work pieces such as sheets of board and processing parts. -

3.7 Setting alarm thickness limits The instrument will alarm if the measurement is out of limits. When the measurement is lower than the low limit or higher than the high limit, the buzzer will alarm. The alarming limit is set as follows: 1) Press , move cursor to ALARM. - Page 12 Measurement units: metric and Imperial Receiving gain: LOW and HIGH 1. The LOW is mainly used for measuring coarse material with high scatter and small sound absorption, such as cast aluminum, cast copper and other metallic parts. 3) Display resolution: 0.1mm(LOW) and 0.01mm(HIGH) Minimum capture measurement OFF and ON...

Page 17: Measuring Cylindrical Surface
5.4 Measuring cylindrical surface When measuring cylindrical material, such as pipes, oil tubes, etc., it is very important to select properly the included angle between the probe’s crosstalk interlayer plate and the axial line of the material to be measured. Briefly to say, first couple the probe with the material to be measured, make the probe’s crosstalk interlayer plate be perpendicular or parallel to the axial line of the object, shake the probe vertically along the axial line... -

will cause abnormal readouts even no display (generally, the abnormal readout is less than actual thickness). In this situation, this kind of material doesn't apply to be measured with this instrument. 5.9 Reference test piece When making accurate measuring for different materials under different conditions, the more the standard test piece is near to the material to be measured, the more accurate the measurement is. -

first, and then measure the work piece with the measured speed. 5.10 Several measuring methods a) Single measuring way: measurement at one point. b) Double measuring way: measure with probe at one point twice. During the two measurements, the probe’s crosstalk interlayer plate should be placed in perpendicular direction, and take the min. -

value. For attenuation under different frequencies, it will increase as the frequency. Secondly, due to coarse crystal particle and if coarse out-phase structure exists, it will cause abnormal reflection, i.e. the grass-shaped echo or tree-shaped echo, so that the measuring will have error reading, and cause wrong judgment. -

the actual thickness. Another error result is called “pulse envelop, cyclic leap”, its result is that the measured value is larger than the actual thickness. To prevent these kinds of errors, please repeat the measurement to check the results. 6.2 Rust, Corrosion and Pit The rust and pit on the other surface of the object will cause irregular change in readouts. -

transmitting speed in these two materials, which will cause error. In addition, different thickness in oxidation layer will cause different error. Please be careful in this. One can make a reference piece from a batch of objects by measuring with micron micrometer or caliper, and use it to calibrate the instrument. -

to prevent rust. When one wants to use them again, first clean them, then he can have normal operation. 7.2 Cleaning the Instrument’s Case Alcohol will corrode the case, especially the LCD of the instrument. Therefore, when you clean the instrument, you can do that just with some clean water and clean it slightly. - Page 25 The component of the instrument is damaged and it is impossible to measure. The LCD is abnormal. c.During normal operation, the error is too large. The keyboard doesn't function or is in disorder. Since Thickness Gauge is a high-tech product, its maintenance should be conducted by professional trained person.
