Megger AVO410 True RMS Digital Multimeter

£129.00 Ex VAT

An autoranging, true RMS digital multimeter, the Megger AVO410 is a great tool for use in electrical testing procedures and allows users to carry out testing with a high degree of accuracy.

The AVO410 is able to perform AC/DC voltage measurements, AC/DC current measurements, resistance testing, frequency and capacitance testing. Multiple measurement ranges are available for each parameter and, since the AVO410 is autoranging, it will automatically adjust itself as needed to the correct range. It is also possible to override the autorange facility and use manual ranging if this function if preferred by the user.

Whether you’re working on basic domestic electrical systems of working on a complex system in poor lighting, the Megger AVO410’s backlit LCD screen means you can always see test results. It’s also possible to use the AVO410’s RS232 interface to communicate testing data to PC for further analysis (requires optional Megger software – sold separately).

In addition to this the AVO410 also contains additional features such as MIN/MAX measurements, a data hold function and a continuity buzzer.

This DMM comes as standard with a set of test leads which come with fully GS38 certified tips.
