Basic Meter
Product Code : EL-LM-10392
Quick answer: The Basic Meter is a dual-purpose teaching meter that works as either an ammeter or a voltmeter, selected by sliding the scale. It covers currents from 100 µA to 5 A and voltages from 100 mV to 50 V, so one instrument serves many circuit demonstrations. Lab Exports manufactures it in Delhi for schools, colleges and universities.

How it is used
An ammeter and a voltmeter can share the same moving-coil movement; what differs is how the meter is connected. As an ammeter it goes in series, so the circuit current flows through it; as a voltmeter it is connected in parallel across the component whose potential difference is being measured. The Basic Meter lets a class see both uses with a single instrument, because sliding the scale changes the reading from current to voltage.
- Decide whether current or voltage is to be measured and slide the scale to match.
- For current, open the circuit and connect the meter in series, observing the polarity marks.
- For voltage, connect the meter across the component, in parallel with it.
- Start on the largest range available and work down until the pointer gives a clear reading.
Typical classroom uses are verifying Ohm's law, comparing the current in series and parallel circuits and measuring the terminal voltage of cells and battery eliminators.
Key features
- Two instruments in one: ammeter or voltmeter, chosen by sliding the scale.
- Current measurement from 100 µA up to 5 A.
- Voltage measurement from 100 mV up to 50 V.
- Teacher's guide supplied to support demonstrations and lesson planning.
- Saves bench space and budget where one meter must cover both quantities.

Frequently asked questions
How does the Basic Meter switch between ammeter and voltmeter?
By sliding the scale. The same instrument then reads current from 100 µA to 5 A or voltage from 100 mV to 50 V.
Is a guide supplied with the basic meter?
Yes, a teacher's guide is supplied for classroom demonstrations.
