Move the indicator to the surface and then zero the gauge. Press down softly on the base of the gauge, if the indicator moves, then the surface is not level. Check and re-clean both surfaces and perform the test again.
How do you use a height gauge step by step?
How to Read a Height Gauge Lock the arm in place after positioning it on top of the piece being measured. Find the “zero” (“0”) on the vernier scale that traveled with the arm along the length of the shaft. Record the number on the vertical shaft that falls opposite or just below the zero marking on the vernier scale.
How does a height gauge work?
A height gage is a measuring instrument in which a slider with a measuring stylus moves relative to a measuring scale on a beam and in which this motion is along a single vertical axis nominally perpendicular to a reference plane on the instrument base.
How accurate are height gauges?
A typical height gauge is good to a thousandth (0.001″). A micrometer or electronic height gauge is accurate to a tenth (0.0001″) or sometimes even better. The primary weakness in accuracy for a height gauge is how square it is to the reference plane being measured.
How do you read a digital height gauge?
When taking measurements using this type of height gage, place the arm in position at the top of the object that you wish to measure. When this is done, find the digital display on the height gage and take note of the number that is shown on the display. This number is the height of the object that you are measuring.
What must be done before using a digital height gauge?
Preparing A Digital Height Gauge Dry the height gauge’s surface after cleaning it. Clean the measuring jaw before attaching it to the instrument. Make the slider on the scale free from moving by loosening the locking screws. Finally, make sure that the surface of the object to be measured is clean and dry.
How do you calibrate a height gauge?
Divide the total measurement range of IUT into two equal parts. Randomly select six checkpoints in the lower half of the measurement range. Select two additional checkpoints in the upper half of the measurement range. With measurement contact in its lowest obtainable position, adjust gage to indicate zero.
What is the range of height gauge?
They are generally available in measuring size ranges from 6 inches to 6 feet. Models can have imperial (inch) or metric (mm) scales or both on them.
What does the Vernier height gauge do?
Vernier height gauge used to measure vertical dimension from reference ground. Vernier Height Gauge consist of a graduated scale or bar is held in a vertical position by a finely ground fixed base.
What is height gauge least count?
Least Count of a Height Gauge: Least count is the difference between one smallest reading of the main scale and one smallest reading of vernier scale. A common and simple mechanical vernier height gauge has a least count of 2 0.02 mm.
How do you check parallelism with height gauge?
Move the target or height gauge straight forward to perform measurement. The difference between the largest measured value (highest height) and the smallest measured value (lowest height) is the parallelism value.
How accurate is a micrometer?
The expected accuracy of a micrometer as established using the Vernier scale is 0.01mm.
What is difference between surface gauge and height gauge?
In the toolroom, the distinction between a height gauge and a surface gauge is that a height gauge has a measuring head (whether vernier, fine rack and pinion with dial, or linear encoder with digital display), whereas a surface gauge has only a scriber point.
How do cameras measure height?
Using the app appears to be rather simple. Simply launch Measure, point the phone’s camera to an object, then pick two points to measure the distance in between. The virtual tape measure can measure either height or length. Measurements done by the app are not always accurate.
Is standard for digital height gauge?
Types. Standard height gauge with vernier graduation and digital height gauge. Generally has size from 150mm to 1000mm.
How do you calibrate a digital indicator?
Detailed Procedure Using index finger, depress the IUT contact point slowly and evenly over the full range, slowly allow the contact point to return to its starting position. Securely position the attachment arm onto the indicator checker. Position the micrometer thimble and test indicator to obtain zero readings.
How is the Vernier height gauge generally specified?
Explanation: Vernier height gauge is an instrument which is used to determine the height of objects. Sizes available for Vernier gauge is in the range of 150 mm to 500 mm. It can also measure the depth, breath and length of the specified objects.
Which scriber is used in height gauge?
Stainless Steel Height Gauge Scriber And Clamp Material Stainless Steel Finish Polished Pack Type Box Material Grade SS304 Color Grey.
What is the difference between vernier caliper and vernier height gauge?
The basic difference between screw gauge and vernier caliper is that screw gauge is used to measure only external measurement while vernier caliper is used to measure external as well as internal measurement. The least count of vernier caliper is 0.01mm while the least count of screw gauge is 0.001 mm.
How do you adjust a Vernier height gauge?
Tighten the fine adjust lock screw, and loosen the slide carriage lock screw. 2. Turn the fine adjust feed screw to attain the desired height setting. As with vernier calipers, the scale is read off the main scale and off the vernier scale at the point where the lines match.
How many types of gauges are there?
All gauges can be divided into four main types, independent of their actual use.
