■ Features

▲ Fully automatic measurement can be realized.

▲ The use of engineering plastic chassis is strong and durable, effectively guaranteeing the safety of testers and the system.

▲ The instrument has automatic range switching function to ensure test accuracy.

▲ The electronic principle circuit combined with DSP technology makes the test stable and strong anti-interference ability.

▲ After the measurement is completed, various parameters are automatically calculated, which is convenient for customers to analyze and test.

▲ Large-screen Chinese character LCD display, all operations are prompted by the Chinese character menu; data has the power-off storage and browsing functions, and can transmit data online with the computer.

▲Using a large-capacity 7.2V11Ah lithium battery for power supply, which does not have any impact on the test circuit and avoids the protection of the system. At the same time, it is used when there is no power supply on site.

▲ The secondary load test uses a clamp-type ammeter to sample the current without disconnecting the secondary circuit. Can realize on-line measurement without power failure. Automatic switching range: During the measurement process, it can be switched to different positions according to the value of the test object, so that the measurement accuracy and display digits are guaranteed.

▲The working time can be as long as 24 hours (the longest), and it can be measured in the charging state.

▲ A lightweight charger is attached, which is convenient for measurement. When the battery is low, the charger can be connected for measurement.

▲ The instrument is small in size and light in weight.

▲ It can store 480 sets of measurement data, which can be kept for ten years after power failure.

▲ The Chinese interface is displayed on a large screen with an RS232 communication interface.
