CITY MULTITESTER Instrumentation and Control CpE 511 NAME: KURT RUSSEL C. CHUA September 01‚ 2012 CYNTHIA C. GONZAGA Date of Submission INSTRUCTOR: ENGR. JAY S. VILLAN‚ MEP-EE Introduction A multitester or multimeter is a device which can be used to gather data about electrical circuits. A basic multitester can measure resistance‚ voltage‚ and continuity; while more advanced versions may be able to provide additional data. This tool can be very useful to have

Discussion. 1. When we want to measure voltage reading‚ the multimeter must be parallel with the component that we want to measured. The red on the high voltage side‚ and black on the lower. When measuring current‚ amperes‚ the multimeter must be in series with the component. Remove one side of the component and connect the black multimeter lead to the board where the component was plugged in and the red lead connects to the loose component. The difference between the two is that if we measure

Tutorial 01 DC Ammeter Example 2-2 A 200-µA meter movement with an internal resistance of 550-Ω is used in 0- to 500-mA ammeter. Find the value of the required shunt resistance. Ayrton Shunt Im Rm I - Im Rc Rb Ra I2 I3 I I1 Example 2.3: Compute the value of the shunt resistors for the circuit. Given that Rm = 1.2kΩ‚ Im =150 µA‚ I1=5mA‚ I2=50mA‚ I3=200mA. Check : Rsh = Ra + Rb + Rc always! + - Fig. 3: An Ammeter using Ayrton shunt. Ammeter Insertion Effects

Premium Capacitor Ohm's law Electrical resistance
states that the total current entering a junction must equal the total current leaving the junction. These laws‚ however‚ cannot be proven or tested without the aid of a multimeter. A multimeter is an instrument designed to measure electric current‚ voltage‚ and usually resistance‚ typically over several ranges of value. The multimeter has different programs to measure voltage‚ current‚ resistance‚ etc. produced from one of two types of circuits. The first type of circuit is a series circuit. A series
