A Guide to Finding the Best Voltage Tester in The Market
Sometimes your appliances fail to work. Or you experience short or open circuit. When you want to check on fuses of your car amplifier for example; the uses are so many. What you need is a multimeter. This, you will use, to check for voltage, resistance, and current. The more advanced ones can measure even capacitors and frequencies. It all depends on what your needs are and your budget at hand.

What is A Multimeter?
Also called a multitester or a VOM (Volt-Ohm-Milliammeter), it is an electronic measuring instrument which uses several measurement functions and combines them into one unit. Typically, a VOM measures resistance, voltage, and current. An analog multimeter usually has a moving pointer to display the readings. A digital VOM (DMM or DVOM) combine several tasks into one. A number of other features were also put into places like the display screen and buttons in place of the pointer and tuning buttons. The first was made in 1977, in a bid to increase reliability and accuracy and since then, it has all been digital for the multimeters.
The DMM usually features a screen display where readouts can be viewed. Buttons for selecting various operations, although they vary with models. A rotary switch for selecting primary measurement value- ohms, amps, volts. Input jacks where test leads are inserted. The input jacks, also known as test leads, are flexible insulated wires. Red is for positive while black for negative. They serve as the conductor from the DMM to the item being tested. The probe tips for testing circuits.
‘Counts' is used to describe the DMM's resolution. This is how fine the meter can make a measurement. This will help a technician to determine the possibilities of a slight change in the measured signal.
Before using any electrical test equipment, always first refer to the user manual for proper operating procedures, safety, and limits. Each use with a digital multimeter poses a potential hazard that must be considered when taking electrical measurements.
Benefits of a DMM
The benefits of a digital multimeter are numerous. Here are a few that are the most important, especially when you do not know what look for, as operations and properties vary.
- They can be used in testing diodes, capacitors, and transistors, with the more advanced measuring frequency.
- The LCD screen ensures that accurate reading is made. This reduces reading and interpolation errors.
- There is a reduction in cost, power requirement, cost and size since the integration of several circuits.
- It has an auto polarity function. You can place the probes into the opposite polarities and to get a negative output. Parallax errors are eliminated so that you get the same value.
- It has no moving parts making it free from wear and shock failures.
- They are of a portable size and can be carried everywhere.
- Some have microprocessors and can store readings for further processing.
