YNLB-II Leakage Protector Tester is mainly used to test the leakage action current, the leakage non-action current and the leakage action time of the leakage protector. The test current is 0-500mA divided into ten gears, and the time test range is 0-799ms, 16 characters This tester is hand-held, small in size, light in weight and easy to carry. It is a test instrument for on-site or indoor detection of various leakage protectors.

The YNLB-II leakage protector tester is equipped with a "manual/automatic" switch button. The LCD screen directly above displays "AUTO 000ms (Note: AUTO=automatic), which is the automatic detection state. When the "shift" button is used to select During the rated operating value test, if the trip is not possible, the test value will be automatically increased by one level after 1 second. Continuous testing until the leakage protector is tripped and disconnected. At this time, the red light on the left vertical row corresponds to the actual level. Leakage action current value, the LCD screen directly above displays "AUTO xxxms (xxx is the action time value of the corresponding current gear).
