![]() Step6: The tool is withdrawn and the reading taken directly from the large LCD display screen. Step5: Tighten the clamping nut of the depth gauge. Step4: Push the ruler of the depth gauge all the way down until the measuring surface touches the bottom of the item being measured thoroughly. Step3: Press the ZERO buttons to set zero. Step2: Press the MM/INCH button to select a unit system needed. Step1: Before measuring, press the ON/OFF button to switch on power. The diagrams below show how the depth gauge is used correctly: Keep in mind avoid touching any of the measuring surfaces of both the subject being measured and the depth gauge with bare hands as it may cause inaccuracy due to the sweat on your hands (if you don’t wear the gloves while measuring). Step5: Move the slider backward and forward, check them to see if the display screen and all the buttons work properly. Step4: Loosen the locking screw of the digital depth gauge. Step3: Clean the measuring faces of the depth gauge with clean cloth (or soaked with cleaning oil) Step2: Clean the surface of the protective sticker with clean cloth (or soaked with cleaning oil) Step1: Clean the measuring surface of the item being measured with clean cloth (or soaked with cleaning oil) The following steps illustrate the correct way to use the digital depth gauge: These simple, inexpensive tools are typically about 150mm long, and they can even measure up to longer range, such as 1000mm. The digital version is capable to output measurements to a wide variety of peripherals and data collection devices. Depth gauge types include digital tire thread depth gauges, digital depth gauges, single hook type digital depth gauges, needle digital depth gauges, double hooks digital depth gauges, digital depth gauges with adjustable base, vernier depth gauges, and dial depth gauges. The base, which is machined flat and at right angles to the ruler, is placed on a reference surface and the ruler lowered into the hole or recess until its bottoms.ĭepth gauges comes in various configurations, depending on the specific application. There is a base through which the ruler can slide up and down, and a locking screw on the cover to clamp the ruler in place. The depth gauge consists of a ruler—usually a narrow one to measure the depth of holes, counter bores, etc. In other word, a depth gauge is a variation of the ruler. A depth gauge is a precision measuring instrument, designed specifically to measure the depth of holes, recesses, cavities and distances from a plane surface to a projection. ![]()
