Notes for safe operation
- The AC-DC Voltage Divider, manufactured by Wuhan UHV, is an ideal instrument for high-voltage measurement. It is primarily used for measuring AC and DC high voltages in power systems, as well as in electrical and electronic equipment manufacturing sectors.
- The device consists of a high-voltage divider and a low-voltage display meter, which are connected via a dedicated matching cable.
Technical Parameters
- Divider ratio: 1000:1
- Insulating medium: Dupont dry dielectric material
- AC measurement mode: Ture RMS
- Temperature: 0~40℃
- Humidness: ≤85%RH
Product characteristics
- High Precision: Utilizes precision high-voltage thin-film capacitors and precision high-voltage glass-glaze resistors, featuring high input impedance to reduce test current and power consumption, thereby improving instrument accuracy and stability. Signal amplification is achieved with high-performance operational amplifiers, and dual-integral AD sampling technology is employed. The four-and-a-half-digit LCD display offers a maximum resolution of 0.001 kV, making this a new-generation high-voltage electrostatic voltmeter.
- Excellent Anti-Interference Performance: Incorporates specialized shielding technology. The uniform pressure ball, made of aluminum alloy with a smooth and glossy surface, effectively improves the electric field distribution around the ball, prevents tip discharge, and enhances measurement data anti-interference capability. The low-voltage display instrument is housed in an all-metal enclosed shielding structure, and the high-voltage divider is connected to the low-voltage display meter via a high-quality coaxial cable, minimizing the impact of high voltage on the indicator and achieving high stability and linearity.
- Safe and Reliable: The AC-DC voltage divider consists of a high-voltage divider and a low-voltage display instrument. The high-voltage divider is manufactured using DuPont filling material with a specialized potting process, resulting in a compact structure, light weight, minimized internal partial discharge, and enhanced reliability. It is oil-leakage-free. The coaxial cable connection ensures a safe distance between high-voltage and low-voltage components, guaranteeing safe and reliable operation.
- Simple Operation: A dial switch allows convenient switching between high and low voltage ranges and AC/DC modes. The four-and-a-half-digit LCD directly displays measurement results, making it easy and intuitive—ideal for field inspections.
- Portable and Easy to Carry: Features a portable structure with the entire unit housed in an aluminum alloy carrying case that can be easily disassembled. Its compact size and light weight make it highly convenient to transport and use.
Battery replacement (LV display)
- Turn off the LV display meter using the power switch before replacing the battery.
- Unscrew the four screws on the LV front panel and remove the panel.
- Unscrew the battery box screw, open the cover and replace the 9V battery (observe polarity).
Notes for safe operation
- Keep the area around the device free of debris to avoid affecting measurement accuracy.
- Maintain a safe working distance during high‑voltage measurements.
- Verify all connections, especially the grounding connection, are secure before use.
- After measurement, wait until the meter returns to zero before entering the area.
- Discharge the instrument after DC high‑voltage measurements before handling.
- Do not operate above rated voltage; keep surfaces clean and handle carefully to avoid impact or compression.
- When not in use, store the equipment in its case in a cool, dry place.
- Recommended calibration interval: at least once per year at an accredited metrology laboratory or by factory recalibration.
