The High Precision Leakage Protector Tester is a specialized instrument with an LCD display, ten current gears, and automatic range functionality. It is designed to test the leakage action current, non-action current, and operation time of various leakage protectors. Featuring 10 current gears from 15mA to 500mA (15, 30, 50, 75, 100, 150, 200, 250, 300, 500mA) and a leakage action time range of 0~999ms, it offers convenient and intuitive measurement.
This tester operates on a DC6V alkaline dry battery (LR6 1.5V × 4) and supports test line voltages below AC 250V (rated at AC 220V). It boasts high precision, with leakage action time accuracy of ±(5% + 3dgt) and fear current accuracy of ±(10% + 2dgt). In case of failure, the LCD displays a “fault” message, indicating issues like overly small testable rated action current gears or leakage protector faults.
With a compact design (instrument size: 170mm × 75mm × 30mm, weight: 290g with battery, 350g with package) and 1.8m test lines, it is easy to carry and suitable for both field and indoor inspections of leakage protectors. It supports manual or automatic test modes, with an LCD display domain of 44mm × 27mm. When the battery voltage drops to 4.8V, a low-voltage indication prompts battery replacement, while ensuring measurement accuracy during this period. This tester is an ideal tool for electricians, maintenance teams, and inspection agencies, delivering reliable performance for leakage protector testing.
