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.

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
