Use WE-20 Features in the Shop



WE-20’s features can be used in the shop with the Model 3230 shop stand. The 3230 features include built-in laser optics, smart socket technology and automatic meter form selection.



Ease of Use



With lock-down optics that stay where you put them and a simple push-button design for easy optic selection, the Model 3230 is ideal for van mounting.




Overview



The WE-20 is the most versatile field test unit on the market today. It puts features like true three-phase testing, ratio testing, harmonic analysis, touch-screen display, and a site specific workflow right at your fingertips, even while testing in the field.



Now you can bring the WE-20’s features back to the shop with the Model 3230 shop stand. The 3230 features built-in laser optics, smart socket technology and automatic meter form selection. Connect the WE-20 to the 3230 side panel using the included cables, select the meter form (displayed on the front of the 3230) and you’re ready to test. Not only does the 3230 make testing socket meters a snap but it expands the current capability of the WE-20 to a full 60 amps, allowing the user to test class 320 amp meters.



With lock-down optics that stay where you put them and a simple push-button design for easy optic selection, the Model 3230 is ideal for van mounting. With the 3230 attached you have all the power of the 2350 plus the ability to quickly remove the WE-20 and do testing right at the site. The WE-20/3230 combination is a revolutionary testing package that redefines the state-of-the art in meter testing.
