Precautions for daily use of "NCV" non-contact electric measuring pen
1. Do not use the test pen if it is damaged or cannot operate normally.
2. Do not use the test pen to test the AC voltage beyond the range.
3. Voltages above 30VAC (alternating current) may cause electric shock hazards, so special care should be taken during testing.
Before each use, test it on a known AC voltage circuit within the range to confirm that the test pen can test normally.
4. When the battery voltage of the test pen is insufficient, please replace the battery in time to test.
Product advantages
overcurrent protection
In order to meet higher safety level requirements and eliminate potential safety faults, over-current protection is added to the circuit design of the product. If a fault occurs in the test pen and a large current is generated, the over-current protection can respond quickly, thereby avoiding damage caused by over-current. The high temperature brings some potential safety risks.
overvoltage protection
At the same time, the product has added an overvoltage protection design to ensure that the power supply voltage of the test pen is stable and will not exceed the safe working voltage range.
powerful torch
A high-brightness flashlight is embedded in the product, which can facilitate users to work in an environment with insufficient brightness.
Glue sealing process
On the basis of increasing over-current and over-voltage protection, in order to further provide a safety level and eliminate potential unsafe factors, the key intrinsically safe components are sealed.
Applications
1) Home appliance repair
The maintenance of household appliances often needs to detect the voltage in the wire, and the ncv non-contact electric test pen can complete the detection more safely, quickly and accurately.
2) Industrial plant
In industrial plants, the ncv non-contact test pen can detect whether transformers, motors, water pumps and other equipment are working normally.
3) Laboratory
Electrical experiments are often needed in the laboratory, and the ncv non-contact test pen can detect the generated electric field signal, which is convenient for experimental work.
electrical maintenance worker
Electrical maintenance workers need to frequently check the voltage value of wires, power supplies and other equipment. Using the ncv non-contact test pen can avoid potential safety hazards when directly contacting the power supply.
