Multimeter range

The meter will typically read to zero on the ohms ranges. A multimeter or a multitester, also known as a VOM (volt-ohm-milliammeter), is an electronic measuring instrument that combines several measurement functions in one unit. Find great deals on eBay for multimeter auto range and auto range digital multimeter.

A digital multimeter is an invaluable tool for most electricians and Tester stocks a huge range of multimeters and digital multimeters for fantastic prices. Multiply the resistance reading on an analog multimeter. Look at the range setting that the dial of your multimeter is set to.

This should give you a number to multiply the reading by. So if someone gives you a multimeter with auto- range , put it to use! Just know how to get it into manual mode.

A circuit’s voltage or current can fluctuate quite quickly. With some of the systems, the current or voltage is so sporadic that the auto- range can’t keep up sensibly. Amps on the lower ranges, quick blow type. If your multimeter reads close to zero, the range is set too high for a good measurement. Turn the dial to a lower setting.

If you set the range too low, the multimeter simply reads or OL, indicating that it is overloaded or out of range.

Do not use the meter when the ambient temperature is higher or lower than the specified operating temperature range. If the range is set to 400. In addition to the operating temperature.

Auto- range : This facility enables the correct range of the digital multimeter to be selected so that the most significant digits are shown, i. DMM would automatically select an appropriate range to display 1. Additionally it also prevent overloading, by ensuring that a volts range is selected instead of a millivolts range. Digital multimeters that. How to measure current using a multimeter In order that the multimeter does not alter the operation of the circuit when it is used to measure current, the resistance of the meter must be as low as possible. It is always best to return the meter range switch to the highest voltage range available as this could save damage of the meter is used before the proper range is set.

How to make a voltage measurement with an analogue multimeter. See the photo above for an explanation of symbols used). Autoranging is a great advantage to have on a digital multimeter. Move the range selector to the proper range of DC V. Connect the multimeter in parallel with the circuit to be measured.

Read the deflection of the pointer on the DC V scale. A typical multimeter may include features such as the ability to measure voltage , current and resistance. Multimeter range products online shopping. I bought this for ham radio and automotive trouleshooting.

This is a great multimeter , the auto-ranging feature is very convenient, as is the back light.
