Digital Multimeters

A digital multimeter is a device that provides measurements of circuit parameters such as voltage (volts), currents (amps) and resistance (ohms). Digital multimeters also offer a wide range of AC and DC measuring capabilities to accommodate a variety of applications. Many multimeters include continuity and diode test functions with an audible alarm for enahnced user experience. To find out more, please see our complete guide to digital multimeters.

How do they work?

Through the use of a digital output readout, they are connected to a device and measure typically the voltage and any resistances and give you an output you can measure.

Different types of Multimeter:

• Bench meters – The most accurate of the two device types, the bench meter is a larger device, not very portable. This is because of the extra level of detail it can provide you when measuring certain parameters
  

• Handheld - Very portable and allow you to work on the go and access hard to reach machinery. Not as accurate as their bench counterparts, however they still display a high level of accuracy.

Features and benefits:

• More accurate and easier to use than analogue multimeters
  
• They help reduce reading errors
  
• Digital multimeters displays do not having moving parts, making them free from wear or shock failures
  
• Zero adjustment needed
  
• Some feature thermal imaging built into the device
  
• Handheld units are extremely portable and ergonomically easy to handle
  
• Drop, water and splash resistance
  
• Clamp options available
  
• Some units have built in work lights and laser pointers for hard to access areas
  
• Long battery life
  
• Auto power off features

Where might I use one?

• Electrical testing, plug sockets, lighting and more
  
• Perfect for home renovations
  
• Business safety tests
