The Bluetooth version of the high and low-voltage clamp meter has functions such as peak holding, data holding, data storage, and Bluetooth. Its dedicated clamp ammeter can easily clamp or remove the tested wire by pressing or pulling out the insulation rod, saving time and speed, ensuring high precision, reliability, and stability for uninterrupted testing all year round.
Details of High and Low Voltage Clamp Meter
- The current clamp adopts magnetic shielding and CT digital integration technology, with strong anti-interference ability, high precision and stable test.
- The innovative automatic plug-in and pull-out structure makes it easy for the instrument to clamp or extract the tested wire by pressing or pulling the insulating rod, saving time and convenience.
- Through Bluetooth communication, after installation, the APP (support android system) mobile terminal can be used for test operation and viewing test records.

Applications
The Bluetooth version of high and low-voltage clamp ammeter is widely used in substations, power plants, industrial and mining enterprises, as well as testing stations and electrical maintenance departments for current detection and field electrical operations. It can also be used for high and low voltage ratio testing, which measures the high and low voltage currents of the primary and secondary circuits separately, and then calculates the high and low voltage ratio. Insulated rods are lightweight, with characteristics such as moisture resistance, high-temperature resistance, impact resistance, bending resistance, and high insulation.
How to operate the clamp meter correctly?
- Safe operation
Make sure to understand whether the clamp gauge is suitable for both AC and DC use, and carefully read the instruction manual.
The voltage of the tested circuit shall not exceed the voltage value specified by the clamp meter to prevent grounding accidents or electric shock hazards.
When measuring, maintain a safe distance and avoid contact with live parts.
When using a clamp meter in a high-pressure environment, it should be operated by two people, wearing insulated gloves and shoes, standing on an insulated pad, and complying with relevant safety regulations.
During maintenance, do not operate with electricity to prevent electric shock.
- Measurement operation
Measure the current of only one phase of the wire at a time, and place the wire in the center of the clamp window.
Estimate the current magnitude before measurement, choose an appropriate range, and avoid measuring high currents with low current settings.
The jaws should be tightly closed. If there is any noise, check whether the magnetic circuit joint surface is smooth and wipe it clean.
When measuring small currents, the wire can be wound a few times and placed in the clamp. The actual current is the reading divided by the number of turns.
- Other precautions
After the measurement is completed, place the conversion switch in the maximum range or off position.
When not in use for a long time, remove the battery and store it to prevent battery leakage and damage to the instrument.
Regularly clean the instrument, keep it dry, and store it in a suitable environment.
Following these precautions can ensure the correct use of Clamp Meter, guaranteeing measurement accuracy and operational safety.
