The Mitutoyo 500-197-20 ABSOLUTE 500 series digital caliper is one of Mitutoyo’s original MyCal Ez Digimatic digital calipers. It gives an absolute reading from zero rather than from the last at-rest position. It is made of durable hardened stainless steel to shield its components and for use anywhere in the workshop. It uses Mitutoyo’s ABSOLUTE linear encoder technology, which allows you to “set and forget” the origin and measure in awkward or difficult locations.
This digital caliper has .3-inch/7.6-mm LCD characters and easy-to-reach function control buttons, such as Inch/Metric to convert measurements, Origin to set and retain the original measuring point, On/Off to automatically shut off the caliper after 30 minutes, and Zero/ABS (Absolute Scale) to zero-set the LCD display.
Although identical to dial and vernier calipers in its ability to make precise measurements, the digital caliper also has the LCD, which clearly shows values and increases reading reliability over the other types. The LCD also reflects all ABSOLUTE system activities. The Absolute Scale (ABS) function tracks the origin point you set—even after shutoff. With the caliper on again, you can immediately start measuring, without zero resetting or worrying about overspeed errors. You can "zero out" the LCD before making and comparing incremental measurements without having to subtract the first measurement from the second.
The 500-197-20 has the ABSOLUTE electrostatic capacitance linear encoder. It weighs approximately 1.2 lb (544 g), and has four-way measurement capability: outer diameter (OD), inner diameter (ID), depth, and step, where the butt end of the fixed jaw measures one end of a work piece before its upper/lower or inner/outer "steps" are measured. It has an Upper/Lower Jaw Length of 1.97”/50 mm, Outside Jaw Depth of 1.97”/50 mm, Inside Jaw Length of .97"/24.5 mm, and Inside Jaw Depth of .79"/20 mm. Range is 0 to 8"/200 mm, LCD Resolution is .0005"/.01 mm, Repeatability is .0005"/.01 mm, and Accuracy is rated + or - 0.001"/.02 mm. Also included are origin-setting, zero-setting, inch-to-metric conversion, and on/off automatic shutoff function buttons. A Digital LCD Data Reading Hold function is available with the optional Data Hold Unit (959143), sold separately. An alarm alerts the user to low voltage and scale contamination and counting value composition errors. A rolling thumb wheel makes fine adjustments and a thumb screw locks the scale’s position. Response speed is unlimited. The caliper has no SPC (Statistical Process Control) output; it draws 1/4 the battery power when switched on and about 1/8 the battery power when switched off compared to other digital calipers. The SR44 silver oxide cell battery (938882) lasts for approximately 20,000 hours (3.5 years) of continual normal use and is recommended to maintain constant voltage levels.
A digital caliper is a measuring instrument commonly used for inspection in manufacturing. It has two pairs of jaws on one end attached to a long beam with a marked scale. It takes and displays measurements in both English and Metric units with high-resolution and gearless precision. It comes from the basic caliper, a device used to measure the distance between two opposing sides of an object. The digital caliper allows for the same sort of differential measurements as the dial caliper by zeroing the display at any point along the slide. However, its LCD has replaced the analog dial of the dial caliper with an electronic digital display of the measurement reading as an easily read single value. A digital caliper is commonly used in fields such as metalworking, mechanical engineering, machining, carpentry, and medicine.
Founded in Tokyo in 1934, Mitutoyo is a leader in the metrology field, producing high-quality measurement products, including mechanical, dimensional gauging products, focusing on micrometers, calipers, indicators, and other measurement tools, as well as output gauges, interfaces, data collectors, and analysis software. Mitutoyo formed Mitutoyo America Corporation in 1963, which is headquartered in Aurora, Illinois, with additional locations in the U.S. and Canada.
