Page 7: Getting Started
1 Getting Started About the TKG Series The TKG100 and TKG150 are portable, digital, handheld thickness gauges. The TKG series of ultrasonic thickness gauges are specifically designed to measure the remaining wall thickness of primarily steel structures. Vibralarm (vibrates gauge below/above minimum/maximum thickness value) ... -
Page 8: Probe Zero
Extech Instruments The TKG100 is a base gauge offering a simple user interface packaged in the same custom molded high- density plastic case with rubber keypad as the other more sophisticated models. This gauge offers reliable, accurate thickness readings on mostly steel structures with access to only one side. - Page 9 working in accordance with electronic zeroing procedures. This feature is particularly important on high temperature materials and when the transducer becomes worn. Important Notice: Please make sure the transducer is not coupled to the test piece when the gauge is first turned on and that there is no couplant on the end of the transducer.
