Product Features of Lightning Protection Components:
1. The lightning protection component tester can measure the main parameters of voltage-limiting breakdown and overvoltage ignition type components.
2. The starting voltage can be preset, continuously adjustable from 20V to 1700V for HJFC-2G type, and from 0 to 1999V for HJFC-2GB type.
3. 1/2 LCD digital display, high accuracy, good reliability, clear and intuitive.
4. When testing varistors, it can automatically provide a precise 1mA constant current and 0.75U1mA voltage.
5. When testing gas discharge tubes, the test voltage rises linearly at a rate of 100V/S.
6. Select continuous measurement to perform uninterrupted testing on batch samples.
7. Equipped with high-voltage short-circuit protection, overcurrent protection, self-check, and other functions.
8. Has built-in 190V~260V discrimination and alarm test functions.
9.The lightning protection component tester has higher accuracy and a wider range. During measurement, the range can be set arbitrarily, and an audible alarm is provided for over-range testing. It is suitable for component grouping and inspection, making operation more convenient.

Precautions and Instructions:
1. This instrument is equipped with a range (test range) adjustment function. In use, you can reduce the test voltage as much as possible to lower energy consumption, extend instrument life, and reduce safety hazards. It also reduces test time and improves efficiency. It can be used for grouping screening and inspection. Users can fully and reasonably utilize this function.
Preset voltage adjustment range: 0V ~ 1800V
Range voltage adjustment range: 100V ~ 1999V
If the range setting or test value exceeds 1999V, the display shows an overflow signal "1".
2. The preset voltage value for discharge tube testing is the starting value of the 100V/S rate rising voltage and also the lower limit of the test range. For varistor testing, the preset voltage only serves as the lower limit for judgment; the actual lower limit of the test range always starts from 0V.
3. The preset voltage should be set lower than the upper limit of the range. Otherwise, the test voltage will be under the control of the range (upper limit) limit. During varistor testing, each test completion will have an over-range audible alarm from the buzzer; during discharge tube testing, the green light will be repeatedly lit, accompanied by an over-range audible alarm. At this time, lowering the preset voltage will put the high voltage into the preset state.
