About This Product
When a teacher builds a circuit at the front of the room, a small bench meter is hard to see from the back rows. With interchangeable dials, one demonstration meter can show current or voltage in turn, each dial bringing its own shunt or voltage multiplier in a sealed moulded box, and the centre-zero dials read on either side of zero. School Educational Instrument can supply the Demonstration Meter Dial to schools and colleges in Yemen, Moldova, Costa Rica, Chad, Malawi and Japan.
Frequently Asked Questions
How is the range of the demonstration meter changed?
Each dial carries its own shunt or voltage multiplier in a sealed moulded box, so the range is changed by fitting the dial with the required scale.
Are centre-zero dials available?
Yes. Centre-zero dials are offered in 5-0-5 mA and 10-0-10 mA for current and in 50-0-50 mV and 5-0-5 V for voltage.
