■ functional features of transformer on load switch AC / DC parameter tester

▲ the instrument has large output current, light weight and easy to carry.

▲ the instrument outputs an open circuit voltage of 28V. It can test the transition resistance of 10 Ω under the current of 1A gear, and is equipped with 0.5A and 0.3A gears to facilitate the test of larger transition resistance.

▲ it has perfect protection circuit and strong reliability.

▲ vertical chassis structure, 5.7-inch large LCD display, convenient for field operation.

▲ with U disk storage function, more data waveforms can be stored.
