This paper presents a pointer positioning method based on Hough transform, which turns an arc scale to a transverse rectangular scales, scans the region from bottom to top line by line, determines smaller rectangular area containing pointer only, uses Hough transform in linear theory to detect the pointer position in the region. Experiments show that this method can locate the pointer position quickly and efficiently in analog measuring instruments.

Hanna Fury Nur Ramdany, Heru Winarno in this paper explain that inductors have an important role in the field of electronics. Many values of capacitors and inductors whose values are difficult to translate, namely when capacitors and inductors are of low value and the color of the print is less clear , also considering the human read factor  when an analog measuring instrument is used. From these problems, it is designed an inductance measuring instrument (L Meter) whose results can be directly displayed.The research method used in the manufacture of inductance meter measuring instruments is the literature method and laboratory tests using frequency variables generated or read by the oscillator circuit. The inductance measuring instrument designed in this researc is simple and meticulous measuring instrument that can be read and used by everyone. This digital inductance meter can be used to measure inductance - inductance with a level or a range of measurements between 20μH –100mH.The lower the inductor value measured, the higher the percentage error. So that the tools designed must be able to work well. The average error ratio of an inductance meter with a standard LCR meter is 6.5%. . Keywords: Measuring, Inductor, Microcontroller and LCD DisplayReferencesMimail,B.

This paper presents a pointer instrument calibration method based on template matching, which segments the image that area closest to the pointer by setting the width on the basis of the meter needle positioning, scans the region from top to bottom line by line, determines smaller rectangular area containing calibration digital only, uses template matching to identify numbers theory to identify the calibration digital in the region. Experiments show that this method can identify the calibration digital quickly and efficiently in analog measuring instruments.
