1. About Digital Calipers Digital calipers -- alsocalled Electronic Calipers. The digital calipers come with no line graduated measuring scale. They have two upper jaws and two lower jaws. Among which, there are a movable lower jaw and a movable upper jaw. They consist of three buttons on the protective sticker, the ON/OFF, ZERO and MM/IN button. Besides, there is a locking screw on top of the protective sticker. The reading is electronicallygenerated and digitally displayed on a large LCD display. Digital calipers can provide easy, fast, error-free measurement, plus SPC (Statistical Process Control) analysis and documentation. Usually, a standard 1.5 volt silver-oxide button battery is used for the digital calipers, and they can measure up to 3, 4, 6, 8, 10, 12 or even more inches. Compared with the traditional caliper types, there arefour major outstanding advantages of the Tresna digital calipers as follows: (a) the measurement is read in a single step, namely, the digits can be read very fast from a large LCD digital readout directly and conveniently, (b) it can be zero-setting at any position for incremental measurements, and inch measurements are displayed to within .0005 in. and metric to within 0.01 mm. (c) a buttonpermits you to choose inch or metric measurement quickly, and (d) data can be input to your special printer or computer for processing and printing through the serial (RS-232) or Universal Serial Bus (USB) port in the back of them.
