If you're guilty of discarding electrical objects the minute they appear to stop working it's time you invested in a multimeter. Electrical tests are easy to perform once you know how and this multimeter enables you to diagnose problems in the motors, switches and controls of a vast variety of appliances.
The large LCD display is easy to read and a back light allowing for reading in dark workshops. The central dial has various positions allowing you to choose which is appropriate for the measurement you want to take, making this an essential piece of equipment for general maintenance.
Complete with a PC interface, this is a professional quality instrument, designed for use by technicians and DIY-ers who need accurate and reliable readings. The 3 3/4 digital multimeter has a wide range of measurement capabilities and a sturdy body which is protected by a bright red rubber casing.
