Voltmeter Manufacturer,Supplier and Exporter in India
Product Code : EL-PL-13418
Jlab Export is a leading Voltmeter Manufacturer,and suppliers in India
Voltmeter (code EL-PL-13418) is a compact DC voltmeter with three ranges, 0–3 V, 0–30 V and 0–300 V, wired through binding posts. It measures the potential difference between two points of a circuit, from a single cell up to a bench supply. JLab, in Ambala, India, makes it as model JL330.

Connecting Across a Component
A voltmeter goes in parallel with the component whose potential difference is wanted, positive post towards the positive side of the supply. Its high resistance draws very little current, so the circuit behaves almost as it would without the meter.
Three Ranges a Factor of Ten Apart
Each range is ten times the one below, so the pointer position must be read against the range in use. A single cell read on the 3 V range moves the pointer well up the scale, while on the 30 V range it barely shifts it. Begin high for an unknown voltage and step down to the lowest range that keeps the pointer on the scale.
