Dual Range Ammeter
Product Code : JA-M-7739
The Dual Range Ammeter (SKU JA-M-7739) is a moving coil meter for measuring direct current in school and college electricity practicals. This dual range DC ammeter reads 0–1 A and 0–5 A on a 60 mm scale with 2.5% accuracy, has a zero adjustment and connects through 4 mm socket terminals. JaincoLab manufactures it in India for physics laboratories, science departments and education buyers who need bench meters for student circuit work.
Specifications

Applications of the dual range DC ammeter
In school and college laboratories the ammeter is connected in series with a circuit to measure the steady current flowing through it, so students can record current against voltage, compare components and check predictions in electricity practicals from secondary classes to undergraduate physics.
- Verifying Ohm's law by recording current through a resistor at different voltages
- Measuring current in series and parallel resistor circuits
- Plotting current–voltage graphs for resistors and filament lamps
- Using the 0–1 A range for small currents and the 0–5 A range for higher-current circuits
- Teacher demonstrations of current measurement alongside a voltmeter

Frequently asked questions
What current ranges does the Dual Range Ammeter cover?
It measures direct current on two ranges, 0–1 A and 0–5 A, on a 60 mm scale with 2.5% accuracy.
Can this ammeter measure alternating current?
No. It is a moving coil instrument for DC only, so it is used with batteries and DC power supplies.
How are the leads connected?
The meter has 4 mm socket terminals, which accept standard 4 mm plug leads used in school circuit work.
