Description

Ohm's meter is designed for measuring the resistance in electric circuits. It is housed in unbreakable case with front clear cover. The dry battery cell is fixed to stand from the bottom side.

SHUNT Type

0-2 KW

SERIES Type

0-100 W

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

A domestic electricity meter adopted to operate single-phase 2, wire C1.2mAx8.33 A 12V 50 Hz. 0.01 rev./J and dials reading in joules. The meter is mounted on a wooden bench stand input and output socket terminals. The aluminium disc rotates once for every 100 Joules with the consumption recorded on three digits calibrated 100, 1000 and 10000 joules per division respectively. The instrument records a maximum of 99,900 Joules.
