Taking accurate current measurements is an important part of the repertoire of skills of a technician or electrical engineer. For those people who will need to take accurate current capability measurements without having to break a circuit to measure, the Fluke i400 AC Current Clamp is arguably one of the most cost-effective add-ons available to increase the versatility of your digital multimeter (DMM).

The Fluke i400 AC Current Clamp is a neat, well designed and robust add on to any DMM. This single range 400A AC current clamp is compatible with many Fluke multimeter as well as any other DMM that accepts 4mm-shrouded banana plugs, and has a dedicated AC milliamp measuring range.

When in use and connected to a suitable DMM,  the i400 can measure up to 400 amps of AC current accurately and the 1MA/Amp output ensures that any readings you make on your DMM will be accurate and easy to read. Another useful feature of the Fluke i400 is that it allows you to clamp onto an existing circuit without breaking it, allowing you to take accurate readings quickly and more easily.

Fluke have paid particularly close attention to the design of the i400. Its compact shape means that it is both easy to store and transport for use at home and on site, while its soft, non-slip handle has been designed so that it drastically reduces the risk of accidentally touching live wiring.

Indeed, safety is paramount when using specialist electrical equipment and the i400 is the only clamp in its class that comes with a CAT IV 600V and a CAT III 1000V safety rating. The output cables also stretch a handy 1.5 metres meaning using the unit is practical too.

The Fluke i400 also comes with a one year manufacturer’s warranty included as standard.
