Page 4: Introduction
5. Measure the part (see pg. 6) Protective Cap PosiTector UTG gages ship with a protective plastic cap over the probe. Remove this cap prior to use. Replace it when the instrument is not in use to protect the probe. - Page 5 Wrist Strap DeFelsko recommends attaching and wearing the supplied wrist strap. Protective Lens Shield The LCD is covered with a thin plastic film for protection against fingerprints and other marks during shipment. This film, while usually removed before using the instrument, can be left in place to protect against paint overspray or debris.

Page 6: Certification
Unit of Measurement inch Icon Certification All PosiTector UTG probes include a Certificate of Calibration. For organizations with re-certification requirements, instruments may be returned at regular intervals for calibration. DeFelsko recommends that customers establish calibration intervals based upon their own experience and work environment. - Page 7 PosiTector UTG probes are available for a variety of wall thickness applications: • PosiTector UTG CA / UTG C – dual element, single-echo probe ideal for measuring severely corroded/eroded materials. PosiTector UTG CA models feature a built-in probe, while PosiTector UTG C models feature a probe mounted on a 1m (3ft) cable.
- Page 8 Thus the single-echo technique will produce a thickness result greater than the actual combined coating metal thickness. The PosiTector UTG M and UTG P in multiple-echo mode determine thickness by measuring the time between at least three consecutive back wall echoes.
-
Page 9: How To Measure
The resultant thickness calculation made by the instrument is therefore an accurate measurement of the steel thickness only, disregarding the coating thickness. PosiTector UTG P (Precision) probes automatically switch between multiple echo and single echo operation depending upon the type and thickness of the material being measured. -
Page 10: Surface Conditions
When using the PosiTector UTG P, it is especially important to avoid using excess couplant when taking a reading. The PosiTector UTG P is designed for measuring thin materials and will measure a thin layer of couplant left on the probe face after a measurement. -
Page 11: Calibration, Verification And Adjustment
NOTE: On smooth, uncoated metal surfaces PosiTector UTG M and UTG P probes (in multiple-echo mode) may occasionally be unable to give a measurement result even when the "coupled" symbol appears. Use additional couplant and lighter pressure on the probe when measuring. -
Page 12: Menu Operation
Menu Operation Gage functions are menu controlled. To access the Menu, power-up the Gage, then press the center navigation button. Below is a sample menu for a PosiTector UTG Advanced Model: Memory Statistics Some buttons have a tick box to their Cal Settings right to indicate current status. -
Page 13: Cal Settings Menu
(Center/Select) Cal Settings Menu Zero PosiTector UTG probes must be “zeroed” after a reset and periodically during use. The Zero process compensates for probe wear and temperature. To maintain the best accuracy, perform a Zero when the ambient temperature changes. -
Page 14: Thickness
Calibration Adjustment The PosiTector UTG is factory calibrated. 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 22: Smart Couple Tm
Smart Couple mode maintains a continuous measurement ses- sion regardless of whether the probe becomes physically decou- pled from the material, and analyzes the thickness values of the material at all locations where the probe was coupled. This mode of operation provides a number of advantages. For example, the user can make multiple passes between various points of a material to be measured, and not have to actively con- centrate on ensuring that the probe is physically coupled to the... -

Clear Clears all onscreen Statistics and HiLo tabulations. Memory Management The PosiTector UTG has internal memory storage for recording measurement data. Stored measurements can be reviewed on- screen or accessed via computers, tablets and smart phones. All stored measurements are date and time-stamped. The symbol appears when the Gage is set to store measurement data. - Page 25 Standard models store up to 250 readings in one batch. The Memory menu includes the following options... On: turns memory on and begins recording Off: stops recording (stored readings remain in memory) Clear: removes all readings from memory View: lists group statistics and all stored readings on the display. It will begin by showing statistics based on all readings in memo- ry.

Page 35: Application Notes
Application Notes Application Notes Measuring on pipes (UTG C, UTG CA, UTG CX, and UTG CLF probes) When measuring the thickness of pipe walls, the proper placement of the transducer is important. On pipe diameters larger than 10cm (4 inches), it is recommended to place the probe parallel to the long axis of the pipe. -
Page 36: Measuring On Hot Surfaces
Measuring on hot surfaces Measurements taken at higher temperatures (above 100° C / 212° F) require special consideration. Both material sound velocity and probe zero will change with temperature. For maximum accuracy at high temperatures, adjustment should be performed using a material of known thickness heated to the temperature where measurements are to be performed. -
