Deli Voltage Tester, AC 100–500V, Suitable for Quick Mains Line Testing

Key specs include: voltage measurement range of 100–500 V AC; bright LED indicator; large LCD display showing the voltage value and range; automatic shutoff to prevent over-testing; low-battery indication; precise calibration system; compact, lightweight design with Comfort grip for easy handling.

The tester automatically powers off after a measurement to reduce battery drain and minimize exposure time to live circuits. This helps improve safety and extends battery life, especially when used for quick checks in busy environments.

The LED indicator clearly shows the voltage range, while the LCD displays the exact measured voltage value and its range. Use the device within its 100–500 V range and interpret the numeric reading on the LCD alongside the LED range indication.

It's well-suited for quick voltage checks in homes, offices, and industrial settings—for outlets, switches, cables, electrical panels, and machinery where voltages are expected to be within 100–500 V AC.

Operate with dry hands, keep the device in its insulated Comfort grip, and avoid contact with live conductors. Use the automatic shutoff feature to minimize exposure time, and never use the tester in damp conditions or on damaged equipment. Always follow standard electrical safety practices when testing.

Before first use, ensure the device has a fresh battery and is switched off. If the low-battery indicator appears, replace the battery. After installation, switch it on and perform a basic test within its rated range to confirm proper operation.

The unit features a precise calibration system and is designed for reliable readings within its specified 100–500 V range. For critical or high-stakes measurements, consider validating readings with a calibrated reference instrument and follow your organization's accuracy requirements.

This model is described as a voltage tester with a display and indicators for measuring voltage within its range. It is designed for contact testing and reading voltage values rather than non-contact detection.

Consider the voltage range you most often test (100–500 V in this model), readability of the display and LED indicators, presence of auto shutoff, battery life and replacement ease, size/ergonomics, and overall value for money. If you need a higher voltage range or non-contact testing, review models with broader ranges or different detection methods available on Fepy.

Keep the device dry and clean; wipe with a dry cloth as needed and avoid moisture. Regularly check the battery and replace it when the low-battery indicator appears. Store in a protective case or pouch to prevent damage from impacts when not in use.
