Digital LCD Voltmeter
Product Code : SCL-EAE-11351
The Digital LCD Voltmeter measures DC potential difference across a circuit component or power source. Its selectable 20mV, 200mV, 2V, 20V and 200V ranges allow teachers to demonstrate low-voltage measurements as well as broader classroom circuit applications with one instrument.
The meter is mounted in an ABS plastic desk stand with front terminals for convenient laboratory connections. Battery operation allows it to be positioned on a demonstration bench without requiring a permanent mains connection. The instrument is intended for supervised educational measurement rather than certified calibration or safety-critical testing.
Key Features
Five DC measurement ranges: Select 20mV, 200mV, 2V, 20V or 200V according to the expected circuit voltage.
3.5-digit LCD: Provides a direct numerical reading that is easy to view during individual work or teacher demonstrations.
Desk-stand configuration: Keeps the display inclined for convenient reading on a physics or electronics laboratory bench.
Front terminal connections: Supports straightforward connection across the component or supply being measured.
9V battery operation: Enables portable classroom use without a mains power lead during measurement.
ABS plastic stand: Provides a practical enclosure for routine supervised educational use.
STEM learning value: Supports experiments involving voltage, potential difference, polarity, resistance and basic circuit analysis.

Applications / Uses
Measuring DC voltage across resistors, lamps and other classroom circuit components.
Demonstrating potential difference and electrical polarity.
Supporting Ohm's law and series-parallel circuit experiments.
Comparing voltage drops at different points in a circuit.
Teaching correct parallel connection of a voltmeter.
Equipping school and college physics laboratory meter collections.
Complementing electrical and electronics laboratory apparatus.
How to Use the Digital LCD Voltmeter
Place the instrument on a stable, dry laboratory bench.
Check the battery condition and inspect the terminals and leads.
Estimate the voltage before connecting the meter.
Select the highest suitable range when the voltage is unknown.
Connect the voltmeter in parallel across the component or DC source.
Connect positive to positive and negative to negative.
Energise the circuit and read the value shown on the LCD.
Select a lower range when necessary to obtain a more useful reading.
Disconnect the circuit and switch off the instrument after the experiment.
Safety note: Do not exceed the selected range or the instrument's maximum 200V DC range. Do not use the meter for AC voltage, mains installations or hazardous circuits unless the final technical documentation explicitly approves that application.
Care & Maintenance
Clean the enclosure and display with a soft, dry cloth; do not use solvents or allow liquid inside the instrument.
Store the meter in its protective box in a dry, dust-free location.
Remove the battery before prolonged storage to reduce the risk of leakage damage.
Inspect terminals and leads regularly and replace damaged accessories before use.

Frequently Asked Questions
What is a Digital LCD Voltmeter used for?
It is used to measure DC potential difference across a circuit component or power source. The reading appears directly on its 3.5-digit LCD.
What voltage ranges does this voltmeter provide?
The selectable ranges are 20mV, 200mV, 2V, 20V and 200V DC. Start with a higher range when the expected voltage is unknown.
How should the voltmeter be connected in a circuit?
A voltmeter is connected in parallel across the component being tested. Correct polarity should be observed when measuring DC voltage.
Can this instrument measure AC voltage?
No AC measuring range has been verified for this model. Use it only for DC voltage unless the supplied technical documentation states otherwise.
Is the Digital LCD Voltmeter suitable for school laboratories?
Yes. Its desk-stand design, front terminals and numerical display support supervised physics, electronics and STEM practical work.
Does the voltmeter include a battery and connecting leads?
The instrument operates from a 9V battery, but the supplied battery and lead set should be ed in the final quotation.
