Introducing the technical parameters of high and low voltage clamping ammeters
The high and low voltage clamp ammeter has an automatic insertion and extraction function, specially designed and manufactured for measuring high voltage current. It adopts new CT technology and mask digital integration technology, and is composed of a dedicated clamp ammeter with a high voltage insulation rod.
If no insulated rod is used, it can also be used as a high-precision low-voltage clamp ammeter or leakage current meter, which can accurately measure the current or leakage current from 0.1mA to 1000A.
The unique integrated design of the clamp head and guide area of the high and low voltage clamp ammeter ensures high precision, high reliability, and high stability for year-round uninterrupted testing.

Test of lines with voltage below 60KV (operated with 5 insulated poles)
99 sets of data are stored. During the storage process, the "MEM" symbol indicates that the storage is full, while the "FULL" symbol flashes to indicate that the storage is full
PEAK maintains the test value of automatically maintaining high altitude. Usually, in the test mode, long press the HOLD key until the PEAK light is on, which activates the PEAK holding function
Data retention: In normal testing mode, press the HOLD key to maintain data, and the "HOLD" symbol is displayed
The "MR" symbol indicates that the stored data can be flipped up and down
Overflow Display Overflow Function: "OL A" Symbol Display
No signal indication: When the receiver does not receive the transmission signal, the "no --" symbol is dynamically displayed
After about 15 minutes of automatic shutdown, the instrument panel will automatically shut down to reduce battery consumption
When the battery voltage is below 4.8V, the low battery voltage symbol is displayed to remind you to replace the battery

The high and low voltage clamp type ammeter is connected to an insulated rod and can be used for measuring the current of high-voltage lines below 60KV. It can also measure online current and has functions such as peak holding, data holding, data storage, and infrared transmission;
Its dedicated clamp ammeter can conveniently clamp or withdraw the tested wire by pressing or pulling out the insulation rod, saving time and speed. It is widely used in substations, power plants, industrial and mining enterprises, as well as testing stations, electrical maintenance departments for current detection and field electrical operations.
