Demonstration Meter
Product Code : JA-M-7742
The Demonstration Meter dial 0–10 A DC (SKU JA-M-7742) is an interchangeable scale dial that turns the classroom demonstration meter housing into a large ammeter reading up to 10 A DC. Each demonstration meter dial is a 315 × 115 mm laminated plastic panel with a sealed moulded box at one end holding the shunt or multiplier for its scale. JaincoLab manufactures the dial in India for physics teachers who demonstrate electrical measurement to a whole class.
Specifications
This listing is the 0–10 A DC dial: a laminated plastic scale panel of 315 × 115 mm with a sealed moulded box at one end containing the shunt appropriate to the scale, made for use in the demonstration meter housing, with dials for other AC and DC current and voltage ranges listed in the same series.

Applications of the demonstration meter dial 0-10 A DC
The 0–10 A DC dial is fitted to the demonstration meter housing when a teacher needs the whole class to read larger direct currents, and it also shows students how a shunt inside the dial extends the range of a sensitive moving coil movement.
- Class demonstrations of direct currents up to 10 A in circuits powered from DC supplies
- Explaining how a shunt extends the current range of a moving coil meter
- Switching between current and voltage dials to show one movement used as different meters
- Comparing readings on the large demonstration scale with student ammeters on the bench
