LCUA-1999 High Voltage Digital microampere MeterIt is a high-voltage ammeter used to measure the AC/DC withstand voltage and leakage current of high-voltage electrical appliances or insulation materials. The instrument is mainly used for AC and DC testing of high-voltage test transformers, and is an ideal tool for testing AC and DC high-voltage leakage current. The measurement of leakage current in AC and DC withstand voltage is an important test item for measuring the leakage current of high-voltage test samples. However, traditional pointer ammeters have large reading errors when measuring leakage current,Disadvantages such as inability to protect against surge current. High voltage digital microamperes have overcome the aforementioned drawbacks.

LCUA-1999 High Voltage Digital microampere MeterIt has reliable use, is not afraid of discharge shock, high accuracy, clear digital display, stable indication, large range, strong overload capacity, and overload protection function. In order to prevent stray currents from entering the meter at the testing site, the material of the instrument housing is selected as a lightweight metal housing to ensure good shielding of the instrument. Strong ability to resist interference and surge current, it is an ideal product to replace traditional pointer ammeters.

Product Features

a) Small in size, lightweight, more aesthetically pleasing, reliable, easy to operate, and fully functional, it is an ideal replacement product for the new century.

b) By adopting technology and process manufacturing, pulse train logic array modulation, high-power IGBT devices, and phase fuzzy control, the output stability is higher and the wave coefficient is smaller.

c) High precision and accurate measurement. The output voltage regulation adopts a single multi turn potentiometer, which ensures a smooth boosting process, high adjustment accuracy, and has coarse and fine adjustment functions. The instrument has high and low voltage ends for measuring leakage current, and the high voltage end is displayed with a spherical shielded digital meter, which is not afraid of discharge impact and has good anti-interference performance, suitable for on-site use.

d) The voltmeter on the control box directly displays the voltage value applied to the load test sample, without the need for an external voltage divider or current limiting resistor during use. The wiring is simple and the operation is convenient.

e) Negative polarity output, zero start, continuously adjustable, with various protection functions such as overvoltage, overcurrent, return to zero, grounding protection, and disconnection protection. Strong automatic protection function, safe operation, various technical indicators are superior to industry standards and superior to similar products.

f) With 75% functionality, measuring zinc oxide lightning arresters brings great convenience. There are 75% voltage switch function keys on the control box of this instrument. When the current rises to 1000uA, the 75% button is turned on. At this time, the values displayed on the voltmeter and ammeter are the 75% data. After completion, the boost knob should be immediately returned to the zero position, and the fine adjustment voltage knob should be returned to the zero position. The 75% button switch should be immediately turned to the normal position before conducting other tests.
