Quick Answer: The AC/DC Voltage Measurement Meter 500V is an analog voltmeter that indicates voltage in compatible circuits carrying alternating current or direct current, up to a rated 500V range, intended for supervised laboratory circuit experiments, electrical training panels and equipment demonstrations.
Product Description
The AC/DC Voltage Measurement Meter 500V from LabEquip is an electrical measuring instrument built for indicating voltage across compatible circuits, in either alternating-current or direct-current form. It is intended for students, instructors and laboratory technicians who require a dedicated voltmeter for supervised circuit experiments, electrical training panels and equipment demonstrations involving voltages within its rated 500V operating limit.
A voltmeter is always connected in parallel across the source, load or circuit section being tested, rather than in series with the main current path. This connection method allows the instrument to indicate electrical potential difference without itself becoming part of the circuit’s working current loop, so learners can observe accurate voltage behaviour while the circuit continues to operate as intended.
What distinguishes this meter within LabEquip’s voltage-measurement range is its dual AC/DC capability at a 500V rated scale — a wider range than the general-purpose digital voltage meters in this category, making it suited to demonstrations and training exercises that specifically call out higher-voltage AC or DC sources under supervised conditions. Exact scale divisions, dial markings and accuracy class should be confirmed with our sales team against the specific unit supplied, since these can vary by production batch.
- Dual-mode voltage indication: reads voltage from either AC or DC sources on the same dial, according to the meter’s selected mode.
- Parallel-circuit connection: reinforces the correct method of measuring potential difference in a circuit.
- 500V rated range: suited to training exercises and demonstrations involving higher circuit voltages than a standard bench voltmeter.
- Visible circuit response: allows learners to observe voltage changes as operating conditions vary.
- Reusable laboratory instrument: supports demonstrations, practical classes and technical training.
- Curriculum relevance: suits electricity, power-supply and AC/DC circuit investigations at school and college level.

Care & Maintenance
- Always confirm the meter is set to the correct AC or DC mode before connecting it to a circuit.
- Never exceed the rated 500V range; measuring higher voltages can damage the movement or create a safety hazard.
- Connect the meter in parallel only — never wire it in series with the main circuit current path.
- Handle the dial and glass face carefully to avoid scratches that could obscure readings.
- Store in a dry, dust-free location away from strong magnetic fields, which can affect analog needle accuracy.
- Have the meter periodically checked against a reference standard if it is used for anything beyond basic classroom demonstration.
Why Choose LabEquip
LabEquip supplies laboratory measuring instruments for schools, colleges and technical training institutes, with a focus on accurate documentation and honest specification of what each instrument does. For related electrical measuring instruments, see our Digital Electrical Voltage Meter for a digital-display alternative, our Industrial Digital Ammeter for current measurement, and our Analog Power Monitoring Meter if you need to measure power (voltage combined with current) rather than voltage alone.
Frequently Asked Questions
Is this meter for AC circuits, DC circuits, or both?
It is a dual-mode instrument capable of indicating voltage from either an AC source or a DC source, according to the mode selected on the meter.
What does the “500V” in the name mean?
It refers to the meter’s rated voltage range — the instrument is designed to safely indicate voltages up to 500V within its scale, rather than being limited to a smaller bench-voltmeter range.
How should this meter be connected to a circuit?
A voltmeter is always connected in parallel across the source, load or section of the circuit being measured, never in series with the main current path.
What is the exact scale interval or accuracy class?
This can vary by production batch. Please confirm the exact scale divisions and accuracy class with our sales team before ordering if this is critical for your application.
Is this suitable for a school physics laboratory?
Yes. It is intended for supervised classroom demonstrations, electrical training panels and practical circuit experiments at school and college level.
