For example, the accuracy of a thermometer having a range of 5000OC may be expressed as +0.5% of scale range.  Sample Problem A moving coil voltmeter has a uniform, scale with 100 divisions. The full-scale reading 200V and 1/10 of a scale division can be estimated with affair degree of certainty. Determine the resolution of the instrument in volt.  Sample Problem A digital voltmeter has a read-out range from 0 to 9,999 counts. Determine the resolution of the instrument in volt when the full-scale reading is 9.999V? Sample Problems 1. A resistor with a color code of Red, Brown, Green, Gold is measured in an ohmmeter. It reads 2.05 mega ohm. Calculate the percent error and accuracy of the ohmmeter. 2. A resistor with a color code of Red, Black, Blue, Gold is measured in an ohmmeter. It reads 20.24 mega ohm. Calculate the percent error and accuracy of the ohmmeter. Elements of Electronic Instruments THANK YOU
