Product Features of Lightning Protection Components:
1. The lightning protection component tester can measure the main parameters of voltage-limiting breakdown and over-voltage ignition type components.
2. The starting voltage can be preset, continuously adjustable from 20V to 1700V for HJFC-2G type, and 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-test, and other functions.
8. Has built-in 190V to 260V discrimination and alarm test functions.
9.The lightning protection component tester has higher accuracy and range, allows arbitrary setting of the range during measurement, and provides audible prompts for over-range tests during the measurement process. It is suitable for component grouping and inspection discrimination, making operation more convenient.

Precautions and Instructions:
1. This instrument is equipped with a range (test range) adjustment function. During use, you can reduce the test voltage as much as possible to lower energy consumption, extend the instrument's lifespan, and reduce safety hazards. It also reduces test time and improves efficiency. It can be used for grouping and screening, inspection and discrimination. Users can fully and reasonably utilize this function.
Preset voltage adjustment range: 0V to 1800V
Range voltage adjustment range: 100V to 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. The preset voltage for varistor testing is only used as the lower limit of the range 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 voltage of the range. Otherwise, the test voltage will be under the range (upper limit) control state. During varistor testing, there will be an over-range audible prompt from the buzzer after each test; during discharge tube testing, the green light will be repeatedly lit, accompanied by an over-range audible prompt. At this time, lowering the preset voltage will put the high voltage into the preset state.
