Digital Ohms Meter – 20K?
Product Code : SCL-LM-11116
Quick answer: The Digital Ohms Meter - 20K ohm is a digital ohmmeter that measures electrical resistance up to 20 kΩ (20,000 ohms) and shows the value as a number. It is used in physics and basic electronics practicals to check resistors, compare nominal and measured values and study series and parallel resistance. Lab Exports manufactures it in Delhi for schools, colleges and universities.

How it is used
An ohmmeter measures resistance by passing a small test current from its own internal source through the component and sensing the resulting voltage; the ratio R = V/I is shown on the display. Because the meter supplies its own current, the component must be disconnected from any other power source before it is measured.
- Disconnect the component or circuit to be tested from all power.
- Connect the component across the meter terminals.
- Read the resistance on the display and record it.
- For a resistor, compare the reading with the value given by its colour code and work out the percentage difference.
- Combine resistors in series and in parallel and check the readings against R = R1 + R2 and 1/R = 1/R1 + 1/R2.
Key features
- Measures resistance up to 20 kΩ (20,000 ohms).
- Digital readout gives a direct number, with no pointer scale to interpret.
- Dedicated resistance meter for resistors and components within its range.
- Useful for comparing the nominal and measured values of resistors.
- Supports Ohm's law and series and parallel resistance practicals.

Frequently asked questions
What is the range of the digital ohms meter?
It measures resistance up to 20 kΩ, that is 20,000 ohms. Components of higher resistance need a meter with a wider range.
Can the ohmmeter be used on a live circuit?
No. Resistance must be measured with the component disconnected from any power supply, because the meter drives its own test current through it.
