Page 2: Quick Start
Introduction Introduction Quick Start Quick Start The PosiTector UTG powers-up when the center navigation button is pressed. To preserve battery life, the instrument powers down after approximately 5 minutes of no activity. All settings are retained. 1. Remove the protective rubber cap from the probe. - Page 3 PosiTector UTG probes transmit an ultrasonic pulse into the material to be measured. This pulse travels through the material towards the other side. When it encounters an interface such as air (back wall) or another material, the pulse is reflected back to the probe.

Page 4: How To Measure
The PosiTector UTGM in multiple-echo mode determines thickness by measuring the time between at least three consecu- tive back wall echoes. steel Figure 2 In the figure above, multiple-echo mode measures only the time between echoes. Regardless of whether the steel is coated or not, all times between echoes are the same. -

When the probe senses echoed ultrasound, a coupled symbol will appear on the display and thickness values will be dis- played. While the probe is coupled, the PosiTector UTG continu- ally updates the display. 3. When the probe is removed from the surface, the last measure- ment will remain on the display. -
Page 6: Calibration, Verification And Adjustment
Calibration, Verification and Adjustment Calibration, Verification and Adjustment Three steps ensure best accuracy… 1.Calibration - typically done by the manufacturer or a qualified lab. All probes include a Certificate of Calibration 2.Verification of Accuracy - as done by the user on known reference standards such as calibration step blocks. -

3. Select the Zero menu option and follow the on-screen prompts. Calibration Adjustment The PosiTector UTG is factory calibrated. But in order for it to take accurate thickness measurements of a particular material it must be set to the correct sound velocity for that material. Be aware that material composition (and thus its sound velocity) can vary from stated tables and even between lots from a manufacturer. - Page 8 Thickness The most common method of adjustment is to measure a sample of known thickness. Select a reference standard of material as close as possible in composition to the intended application. For best results, the thickness of the reference standard should be equal to or slightly greater than the thickness of the part to be measured.

When the probe is lifted, the last reading will remain on the display. It is sometimes necessary to examine a larger region to locate the thinnest point. When Scan is selected, the PosiTector UTG will measure at a rate of 20 readings per second and display min/max values. -
