Page 6: Introduction
Congratulations on purchasing an ultrasonic thickness gage AD-3255 of . We recommend that you read through this manual carefully before using the AD-3255 for the first time. Keep the manual nearby for reference. 2-1. Features The AD-3255 can measure the thickness of various materials using a principle similar to sonar, displays the thickness value in 0.1 [mm]... - Page 7 The AD-3255 is equipped with an automatic power-off function: When no operation is performed for approximately 5 minutes, the display blinks for 20 seconds and then the power is turned off. The AD-3255 can measure the thickness of other metal, plastic, ceramics, composite materials, epoxy resin, glass and a variety of other materials.

Page 23: Information And Cautions
5-1. Battery Cautions Use the specified battery. Install and replace with new batteries. Install two new alkaline batteries matching polarities "+ and -" with those of the electrical terminals. Incorrect polarities may result in malfunctions or damage. Do not charge the battery. Do not short the terminals of the battery. Do not disassemble the battery. - Page 24 The surface whose thickness is to be measured should be clean and free of any small particulate matter, rust, or dirt. Make the measurement surface clean and free from particles, rust or dirt. If any of these obstructions are present, the transducer cannot make proper contact.
- Page 25 In this case, it is necessary to select the size of the transducer. Connect the transmitter plug and the receiver plug to the coaxial connectors on the main unit. The plugs can be connected to either the transmitter connector or receiver connector.

"right angle" of the long axis direction. The measurement of narrow pipes uses two direction measurements. One of the directions is perpendicular to the long axis direction, and the other is parallel. The thickness is the smaller of the two values. - Page 27 Measuring Laminated Material In general, there is a difference in the density "sound velocity" between non-laminated and laminated materials "taping, covering or painted with epoxy, polyethylene and adhesive, etc.". Multi-laminated materials may even exhibit noticeable changes in the sound velocity across a single surface.

All materials do not allow sound waves to penetrate. Ultrasonic thickness measurement can be used for metal, plastic, glass and multifarious materials. but it can not use for a part kind of cast iron, concrete, wood, fiberglass "fibre-reinforced plastic"... -
Page 29: Measurement Principle
When the ultrasonic wave is transmitted from the transmitter element of the transducer, the ultrasonic wave pulse "T pulse" is inputted into the material, and the ultrasonic wave pulse "Echo B" is reflected at the bottom, and is received at the receiver element which is then amplified as an electric signal. -
