Introduction to the technical parameters of the high voltage and low voltage clamp-on ammeters
The high and low voltage clamp 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 ammeter with a high voltage insulation rod.
If insulation rods are not used, they can also be used as high-precision low-voltage clamp ammeters and leakage ammeters, which can accurately measure currents or leakage currents ranging 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, reliability, and stability for uninterrupted testing throughout the year.

Testing of lines with voltage below 60KV (operated with 5 insulated poles)
99 sets of data are stored, and the "MEM" symbol indicates during the storage process. The flashing "FULL" symbol indicates that the storage is full
PEAK maintains the automatic high altitude test value. Normally, in test mode, long press the HOLD button until the PEAK light is on, which activates the PEAK hold function
Data retention: In normal testing mode, press the HOLD key to hold the data, and the "HOLD" symbol will be displayed
The "MR" symbol indicates the ability to browse the stored data up and down
Overflow display over range overflow function: "OL A" symbol display
No signal indication: When the receiver does not receive the transmitted signal, the "no --" symbol is dynamically displayed
