Description

Suitable for Industrial Kelvin Double Bridge and Senior Kelvin Double Bridge. Galvanometer Resistance 125 ohms Nominal, Sensitivity 15 mm. scale division per micro amp. time period 2 second, critical damping resistance 1000 ohms and working voltage is 230 Volts AC 50 Hz.

Description

For DC & AC current and voltage. The operation of these meters depend on the reaction of the current circulating in the moving coil and a field of a fixed permanent magnet. Considering the operational nature and design of these instruments. the scale is linear. Since, the direction of the movement rotation depends on the direction of the current flow (polarity) in the circuit. The moving coil multirange meter can be used on direct current circuit and also alternating current with a suitable rectifier inserted in the circuit.

Accuracy	DC + F.S.D. & AC + 2.5 F.S.D.
Scale Length	60 mm approx. with knife edge pointer and anti parallel mirror scale.
Dial Size	80x80 mm, rectangular.
Moving Coil Multirange Voltmeter has following ranges	DC & AC 0-5 - 25 - 50 - 100 - 250 - 500V
Moving Coil Multirange Ammeter has following ranges	DC & AC 10 mA - 100mA - 500 mA - 1A - 2.5A - 5A

Description

For use with Meter Interchangeable. Each dia, comprises a laminated plastic panel 315x115mm with a sealed moulded box at one end which contains the shunt or voltage multiplier appropriate to the scale.
