When combined with a dial gauge, a height gauge can be used to measure height. Height gauges and depth gauges can be considered relatives of hand calipers. The calibration interval for hand calipers, height gauges, and depth gauges is 6 months to 2 years. Buy GLTL Depth Gage General Tools Depth gauge Vernier caliper,0-6/150mm,0-8/200mm,0-12/300mm (digital 0-150mm): Digital Calipers - FREE.One simple and useful method is to use a gauge block to perform measurements. Periodically confirm whether the measurement accuracy has been maintained.Exercise particular care when handling the small inner jaws and the depth probe, as these parts may deform easily if handled roughly.With the scales at zero, the normal state is where no light leaks from the large outer jaws when they are closed.Applying more force to the slider than necessary during measurement may lead to errors caused by the large outer jaws becoming bent.Read the Vernier scale from the left at the position where it overlaps with the gradation of the main scale.In general, this enables measurements in units as small as 0.05 mm. The Vernier scale divides one gradation of the main scale into 20 gradations. Read the gradations on both the main scale and the Vernier scale on the hand caliper.
Also, when measuring a cylinder, be sure to firmly close the parallel surfaces of the large outer jaws around the target. Pushing the slider too forcefully will cause the jaws to be at an angle, which will prevent accurate measurement. During measurement, grasp the main scale and move the slider with your thumb to close the large outer jaws around the target.Level difference measurement: Insert the depth probe or a step into the hole or level difference to perform measurement.Inner diameter measurement: Insert the small inner jaws inside the measurement target, and widen the jaws until there is no gap between the jaws and the target to perform the measurement.Length (outer shape) measurement: Close the large outer jaws on the measurement target, and then read the values from the main scale and the Vernier scale.View Catalog Construction and Applications
