Selection Guide
- Confirm system voltage: Select a rated voltage range slightly higher than the nominal system voltage to ensure safe and accurate measurement.
- Choose connection type:
- For systems ≤600V: direct-connection voltmeter models are available.
- For systems >600V: select meters matched with appropriate voltage transformer ratios (e.g. 1000V/100V, 1500V/100V).
- Verify frequency: Standard models are calibrated for 50Hz; 60Hz calibration is available for custom bulk orders.
- Check panel dimensions: Ensure your panel has a 76×76mm mounting opening compatible with the 6L2 form factor.
- Custom requirements: Custom dial scales, special ratios and OEM logo printing are available for volume orders.
Installation & Maintenance Instructions
Installation
- Fully de-energize the target circuit and confirm zero voltage before starting any wiring work.
- Insert the voltmeter into the pre-cut panel opening from the front side.
- Secure the meter from the rear using the supplied mounting brackets and fixing screws.
- Connect the meter terminals in parallel with the measured circuit, following the included wiring diagram. For VT-operated models, ensure proper connection to the voltage transformer secondary circuit.
- Restore power and verify normal pointer deflection against a known reference voltage.
Maintenance
- Clean the dial cover periodically with a soft, dry cloth to maintain clear visibility.
- Inspect terminal connections regularly for tightness and signs of overheating or corrosion.
- Avoid prolonged exposure to direct sunlight, high humidity, excessive dust or corrosive atmospheres.
- Recalibration every 2–3 years is recommended to maintain measurement accuracy, especially for high-voltage and precision monitoring applications.
- All electrical installation and maintenance work must be performed by qualified personnel in compliance with local electrical safety regulations.

Frequently Asked Questions (FAQ)
Q: Can the 6L2 voltmeter measure both low voltage and high voltage?
A: Yes. The 6L2 series covers a full range from 15V to 1500V, with dedicated models for each rated voltage. Low-voltage models (≤600V) support direct connection, while high-voltage models (>600V) are used with matching voltage transformers.
Q: Is this voltmeter suitable for DC voltage measurement?
A: No. The standard 6L2 voltmeter is designed exclusively for alternating current (AC) systems. DC-specific variants with different internal structures are available as separate product models.
Q: What does accuracy class 1.5 mean?
A: Class 1.5 indicates a maximum permissible measurement error of ±1.5% of the full-scale value, which meets the standard requirements for general industrial monitoring and indication applications.
Q: What is the mounting hole size for the 6L2 voltmeter?
A: The standard panel cutout dimension is 76mm × 76mm, with an overall front bezel size of 80mm × 80mm, compatible with all standard 6L2-format panel openings.
Q: Do I need a voltage transformer for a 450V 6L2 voltmeter?
A: No. 600V and below models are designed for direct parallel connection to the circuit. Voltage transformers are only required for rated voltages above 600V.
Q: Can this meter be used outdoors?
A: The standard 6L2 voltmeter has an IP40 front protection rating and is intended for indoor use inside enclosed electrical panels. Outdoor installation requires an additional weatherproof protective enclosure.
