Portable Voltage & Current Trainer

The Voltage & Current Trainer (VIT) is a compact desktop trainer that allows operators to rehearse render‑safe procedures on multiple circuits without going near a live device. With eight individually monitored zones, smart sensing of normally open (NO) and normally closed (NC) cables, and simple one‑button operation, VIT gives EOD, search and technical teams a safe way to practise taking voltage and current measurements on “live‑feeling” target cables.

Powered by a built‑in Li‑ion battery and housed in a rugged PA12 enclosure, VIT is designed to travel easily between classroom, range and exercise locations while providing clear visual and audible feedback on every action.

Key benefits

• Train on eight separate zones: Simulates up to eight individual target wires so users can practise working multi‑line problems, not just single‑cable exercises.
• Smart sense for NO/NC wires: Automatically detects whether each target cable is wired as normally open or normally closed, reinforcing correct diagnostic thinking.
• Realistic voltage & current checks: Designed for repeated practice of voltage and current measurements against the supplied target cables, supporting modern wire diagnostic procedures.
• Simple one‑button operation: An intuitive interface with a single control and OLED display keeps operation straightforward under training pressure.
• Clear visual and audible feedback: The unit indicates changes in each zone with on‑screen, visual and audible outputs, so learners can immediately see the effect of their actions.
• Discreet “distaff” mode: Instructors can use the discreet configuration‑view function to check how zones are set up without revealing the solution to students.
• Fully portable: Built‑in Li‑ion battery, micro‑USB charging and around 14 hours of use per charge make VIT genuinely field and classroom ready.

Why choose the VIT

• Purpose‑built for wire diagnostics: Specifically designed to maintain and improve electronic wire diagnostic procedures, not a generic electronics trainer.
• Aligned with Trimax tooling: Ideal companion for diagnostic tools (such as DCM, RDT and DBAT) and your existing meters.
• Supports structured training pathways: Fits naturally between basic classroom theory and more complex Electronic Diagnostic Boxes or live‑task training.
• Local advice and support: J3Seven can assist with course design, SOP integration and through‑life support for your training fleet.
