Lab manual for digital multimeter

 · Digital Electronic 1 Laboratory Manual. All readings should be within 10% of their marked voltages. Some interface devices in digital logic require both positive and negative polarity power supplies, and in those circuits, it is common to see a 0V ground reference. Turn off the trainer for the next measurement. 3. Variable Voltage Supply Tech Note: Digital Multimeters and ClampMeters use different techniques internally, to measure AC, DC voltage, Resistance and Amperes. An advantage of a digital multimeter is their accuracy and input protection. Their input resistance or impedance is very high, in the range of 1,, to 10,, ohms, so there is little effect on the. Digital Multimeter iv. Unknown Resistances Circuit Diagram: Theory: A Kelvin Bridge is a measuring instrument used to measure unknown electrical resistors below 1 ohm. It is specifically designed to measure resistors that are constructed as four terminal resistors.

Turn on the main power switch at the back of the unit; the power indication should lit (2) Select the output voltage with the dial (5). Connect the positive input terminal of your device with the output (+) terminal (4) and connect the negative input terminal with the output (-) terminal (3). Electronic Measurement Instrumentation (EEF) LAB MANUAL(V SEM ECE) Page 6. Vrms = effective value Vp = simple peak or crest value Vpp = peak-to-peak value Vmom = momentary value. Frequency measurement. T = time in seconds for one period F = recurrence frequency in Hz of the signals, F = 1/T, T. tot. Lab 2 multimeter. 1. INTRODUCTION A multimeter or a multitester, also known as a VOM (Volt-Ohm meter), is an electronic measuring instrument that combines several measurement functions in one unit. A typical multimeter would include basic features such as the ability to measure voltage, current, andresistance.

Measuring Resistance with the Digital Multimeter: Resistance measurement with to calculate Systematic *V (Volts) and my lab manual is not very helpful. Energy Meter, Tachometer, Rheostat, Various Capacitors, Various Resistors, AC and DC Power Supply. THEORY OF EXPERIMENT: AMMETER. Experiments Digital Multimeter, VOM or. VTVM (See discussion on page 3). Experiments The Meter needs at least Ω input impedance. Experiment 8.
