QM-Height Series 518 This is a high precision ABSOLUTE digital height gauge that offers you the following benefits: It has a high accuracy, high resolution ABSOLUTE linear encoder for position detection. You can easily implement frequently used measurements, such as inside/outside diameter and pitch calculations, by icon-based coands that also support easy one-key operation. You can measure the inside/outside diameter via a unique process (detect the circle apex and process by tracing measurement). GO/±NG judgement is performed by setting the upper and lower tolerances. If a judgement result is out of tolerance the display backlighting changes from green to red, so you can see the issue iediately.

Potential causes of error Like the caliper, the error factors involved include parallax effects, error caused by excessive measuring force due to the fact that a height gage does not conform to Abbe's Principle, and differential thermal expansion due to a temperature difference between the height gage and workpiece. There are also other error factors caused by the structure of the height gage. In particular, the error factors related to a warped reference edge and scriber installation described below should be studied before use. 2. Reference edge (column) warping and scriber installation Like the caliper, and as shown in the following figure, measurement errors result when using the height gage if the reference column, which guides the slider, becomes warped. This error can be represented by the same calculation formula for errors caused by nonconformance to Abbe's Principle. f = h = h a h Installing the scriber (or a lever-type dial indicator) requires careful consideration because it affects the h size of any error due to a warped reference column by increasing dimension h in the above formula. In other words, if an optional long scriber or lever-type dial indicator is used, the measurement error becomes larger. Example: Effect of measuring point position When h is 150, the error is 1.5 times larger than when h is 100. h 3. Lifting of the base from the reference surface When setting the scriber height from a gauge block stack, or from a workpiece feature, the base may lift from the surface plate if excessive downwards force is used on the slider, and this results in measurement error. For accurate setting, move the slider slowly downwards while moving the scriber tip to and fro over the gauge block surface (or feature). The correct setting is when the scriber is just felt to lightly touch as it moves over the edge of the surface. It is also necessary to make sure that the surface plate and height gage base reference surface are free of dust or burrs before use. 5 4 3 2 1 0 11 10 7 h h a h a Mechanical Digit Height gage Measuring upwards from a reference surface Scribing stylus 122.11 Reference surface Scribing stylus 8020 70 0 10 40 40 0 0.01 50 50 50 50 10 0 40 40 8020 70 Measuring downwards from a reference surface Reference surface Counter 124 0 0 0 10 10 0 8 7 5 Dial 0.11 8020 0.01 8020 124.11 70 70 Reading 124.11 Notes on using the height gage 1 1 8 2 2 7 4 2 8 Counter 122 Dial 0.11 Reading 122.11 4. Relationship between accuracy and temperature Height gages are made of several materials. Note that some combinations of workpiece material, room temperature, and workpiece temperature may affect measuring accuracy if this effect is not allowed for by performing a correction calculation. 5. The tip of a height gage scriber is very sharp and must be handled carefully if personal injury is to be avoided. 6. Do not damage a digital height gage scale by engraving an identification number or other information on it with an electric marker pen. 7. Carefully handle a height gage so as not to drop it or bump it against anything. 1. Keep the column, which guides the slider, clean. If dust or dirt accumulates on it, sliding becomes difficult, leading to errors in setting and measuring. 2. When scribing, securely lock the slider in position using the clamping arrangements provided. It is advisable to confirm the setting after clamping because the act of clamping on some height gages can alter the setting slightly. If this is so, allowance must be made when setting to allow for this effect. 3. Parallelism between the scriber measuring face and the base reference surface should be 0.01 or better. Remove any dust or burrs on the mounting surface when installing the scriber or lever-type dial indicator before measurement. Keep the scriber and other parts securely fixed in place during measurement. 4. If the main scale of the height gage can be moved, move it as required to set the zero point, and securely tighten the fixing nuts. 5. Errors due to parallax error are not negligible. When reading a value, always look straight at the graduations. 6. Handling after use: Completely wipe away any water and oil. Lightly apply a thin coating of anti-corrosion oil and let dry before storage. 7. Notes on storage: Avoid direct sunlight, high temperatures, low temperatures, and high humidity during storage. If a digital height gage will not be used for more than three months, remove the battery before storage. If a protective cover is provided, use the cover during storage to prevent dust from adhering to the column. 24
