Digital Multimeters Are Easy to Carry and Use

FOR IMMEDIATE RELEASE
(Free-Press-Release.com) October 11, 2011 -- 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 may include features such as the ability to measure voltage, current and resistance.

Multimeters may use analog or digital circuits—analog multimeters (AMM) and digital multimeters (often abbreviated DMM or DVOM.) Analog instruments are usually based on a microammeter whose pointer moves over a scale calibrated for all the different measurements that can be made; digital instruments usually display digits, but may display a bar of a length proportional to the quantity being measured.

Modern multimeters are often digital due to their accuracy, durability and extra features. In a digital multimeter (http://www.youroscilloscope.com/dso1200-digital-handheld-scope-meter-2-channel-oscilloscope-p-27.html the signal under test is converted to a voltage and an amplifier with electronically controlled gain preconditions the signal. A digital multimeter displays the quantity measured as a number, which eliminates parallax errors. To begin using the digital multi-meter, you must place the test probes in their proper receptacles. The common probe (black) is placed into the COM (common) position.

You will notice that the selection dial is pointing within the resistance section - in particular, the dial is currently pointing to the continuity position. In this position, when continuity (any resistance) is detected, the digital multi-meter will emit an electronic bell sound. Digital multimeter (http://www.youroscilloscope.com/usb-handheld-digital-storage-scopemeter-oscilloscope-dso-1060-p-30.html) you can make voltage, current, resistance, frequency, period, capacitance and temperature measurements with confidence. You can also monitor and record measurements over time or environmental ranges and view statistical values to see how your circuit's performance is changing. And, dedicated front-panel buttons provide fast access to frequently used functions and parameters, reducing set up time.

Each Hantek digital multimeter provides the feature-rich tools and precision you need for your most demanding measurements. Some digital multimeters are designed to provide the exact readings of the multimeter, while other multimeters provide percentages for an easier reading, according to Fluke. However, the percentages do not always give the tester enough details to make a diagnosis based on the readings. Many digital multimeters (http://www.youroscilloscope.com/oscilloscope-digital-multimeters-c-9_16.html) come with protection mechanisms that are designed to protect the digital multimeter from over voltages.
