Milliammeter Manufacturer,Supplier and Exporter in India
Product Code : EL-PL-12425
Jlab Export is a leading Milliammeter Manufacturer,and suppliers in India
Milliammeter (code EL-PL-12425) is a DC current meter reading 0–500 mA, model JL373/085, in a fully enclosed plastic case with colour-coded binding posts and a zero adjustment. It measures the smaller currents of student circuits, where an ampere-range meter would give too coarse a reading. JLab, based in Ambala, India, makes this meter.

Before the First Reading
With no current flowing, the meter should show exactly zero; if it does not, set it with the zero adjustment, since any offset left in place is added to every reading. Then wire it in series, with current entering at the positive post. The colour coding on the binding posts makes that easy to check before the circuit is switched on.
Keeping Within 500 mA
The full range is half an ampere, so protect the meter while a circuit is being set up. Start with a rheostat at its maximum resistance, or take a first reading on a 0–5 A ammeter, and change to the milliammeter once the current is known to be below 500 mA. Typical uses are the current through a resistor at low voltage, through a small filament lamp, or through a junction diode in forward bias, where the current rises steeply once the diode starts to conduct.

- Moving Coil Galvanometer — centre-zero meter for very small and reversing currents.
- Rheostat 30 Ohm — sliding rheostat for setting the current before it reaches the meter.
