Several classmates and I spent twelve weeks redesigning the multimeter for industrial use. This project was sponsored by Fluke Corporation, a leading manufacturer of tools for professionals. Upon completion we presented our work to the engineering, business, and design teams at Fluke. Because it is now owned by Fluke Corporation some elements of this project cannot be shown here.
Technicians often had to be in two places at once while performing diagnostics and running tests.
Sometimes retrieving the exact wire the technician needed was challenging in crammed electrical boxes.
Especially in industrial applications, there is a large range of wire gauges to interact with for measurements.
Whether in the electrical cabinet or in the user’s toolbox cords are constantly tangled in a ‘rat’s nest.’
Current testing methods require users to remain in dangerously close proximity to active electrical environments while running tests.
Users often have many specialized tools, rather than a swiss-army knife
Many instruments have a sort of learning curve while users become familiar with their interactions
Weight distribution and grip contributed to poor ergonomics
Poor environmental interaction for the device
No organized solution for storing cords
Tough to isolate specific wires for measurements in crowded electrical box
There is often a need for a user to be in two places at once– either remotely monitoring a circuit or testing in one location while adjusting loads in another.
Huge cost benefit by using a single microprocessor to take several measurements
Increased ease-of-use and functionality for three-phase power systems
In commercial and industrial applications the gauge of wires can vary widely
Our solution must be able to make contact around a variety of wire gauges
Magnetically place the 23-400 unit on a breaker box or panel door for hands-free use.
Detach the lead clips from the unit.
Fasten a clip lead to an insulated portion of the desired wire.
For three phase testing and diagnostics, connect all three leads at once.
The 23-400 tablet can be used in place or removed for remote testing and diagnostics.
When finished testing, return the removable tablet to the unit before wrapping the cord and docking the test leads.
Press the power button to turn on the unit and begin testing.
Press the mode button to toggle between current, voltage, or power measurements.
To pair the 23-400 to a Fluke Connect™ enabled device hit the Pair button.
Press the "HOLD" button to pause testing and record a measurement.
The 23-400 is also capable or phase monitoring and can store phase data to a Fluke Connect™ enabled device.
