Page 2: General Introduction 1.1Construction Of The Gauge
1.1Construction of The Gauge General Introduction UM-5 series ultrasonic thickness gauge adopts 2.4 inch color 320*240 dot matrix LCD screen. Launch the ultrasonic through one side of the test material, measure the digitized thickness real-timely, without cutting the object. As a ultraminiature measuring gauge, is researched and developed by our company according to the ultrasonic measuring theory. -

Optional rectification mode: RF+, RF-, full wave, half +, half - Before using UM-5 series, the instrument and probe must be calibrated. Language: Chinese, English, German,... - Page 5 4. Dual Echo calibration：Calibrate the velocity from the test block of known 3.1.3 Two point calibration thickness. 5.Setting the velocity manually： If the material velocity is known, for example the velocity of steel is 5900m/s. The sound velocity can be setting manually. 3.1.1 Probe zero calibration Note: The calibration result is 4.00mm, only under the sound velocity of 5900m/S.

Page 8: Normal Mode
3.3 Normal Mode UM-5 series have three measuring interface: normal mode, A-scan interface, B-scan interface. And there are three display modes of normal interface: Thickness value mode, difference/rate-of-reduction measurement mode, MAX. /MIN. measurement mode. Select “VIEW MODE” CONFIGURATION. ATTENTION: When the probe and the object are not completely coupled, the font in the various interfaces are in GREEN, when properly coupled, they are 3.6 DIFFERENCE MODE INTERFACE... -
Page 9: A-Scan Interface Mode
3.4 A-scan Interface Mode GAIN — Adjust the amplification of echo signal by instrument to allow In this mode, users could view the current thickness value and the A-scan manual increase or decrease in ldB. This function is very useful for the testing waveform at the same time. -

GATE — adjusting the height of the gate.Only when the waveform is higher 2. There are some defects in the testing object, and the gate locks the defect than the gate, the gauge can take the echo and show the value. Attention: this will only show when the GATE specification is highlighted. -

90°in the second measurement, the thinner reading is the thickness value. When testing ultra-thin materials, sometimes ‘’double refraction’’ happens, 3. MULTIPLE-POINT MEASUREMENT which is a kind of incorrect result and the result is twice of the real one. When the reading is unstable, measuring several times within a circle with a Another incorrect result called ‘’pulse envelope, cycle jump’’, which means certain point as center and 30mm as diameter, the thinnest reading is the that the testing result is higher than the real one. -
