Introduction to Technical Parameters of High and Low Voltage Clamp Ammeters
The high and low voltage clamp type ammeter has 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 type ammeter with high voltage insulation rod.
If no insulating rod is used, it can also be used as a high-precision low-voltage clamp ammeter or leakage current meter, which can accurately measure 0.1mA~1000A current or leakage current.
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 continuous testing throughout the year.

99 sets of data storage, indicated by the "MEM" symbol during the storage process, with the "FULL" symbol flashing to indicate that the storage is full
PEAK maintains the test value of automatically maintaining high altitude. Normally, in the test mode, press and hold the HOLD key until the PEAK light is on, which activates the PEAK hold function
Data retention: In normal testing mode, press the HOLD key to maintain data, and the "HOLD" symbol is displayed
Data access indicated by the "MR" symbol allows for scrolling up and down of stored data
Overflow display over range overflow function: "OL A" symbol display
No signal indicates that the "no --" symbol is dynamically displayed when the receiver does not receive the transmission signal
After about 15 minutes of automatic shutdown, the instrument automatically shuts 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

High and low voltage clamp type ammeters are connected to insulated poles, which can be used for current measurement of high-voltage lines below 60KV, online current measurement, and also have functions such as peak holding, data holding, data storage, and infrared transmission;
Its specialized clamp shaped ammeter can conveniently clamp or withdraw the tested wire by pressing or pulling back the insulation rod, saving time and speed. It is widely used in substations, power plants, industrial and mining enterprises, as well as detection stations, electrical maintenance departments for current detection and field electrical operations.
It can also be used as a high and low voltage ratio tester, which measures the high and low voltage currents of the primary and secondary circuits separately, and then calculates the high and low voltage ratio manually. The insulating rod is lightweight and has the characteristics of moisture resistance, high temperature resistance, impact resistance, bending resistance, high insulation, and scalability.
