Product FeaturesProduct Characteristics
- 1. The intelligent lightning protection component tester is suitable for measuring the DC parameters of overvoltage protection components such as zinc oxide lightning arresters (varistors), metal ceramic two - and three electrode discharge tubes, vacuum lightning tubes, etc. It can also be used as a voltage regulator, constant current power supply, and applied in other fields.
- 2. It has functions such as high voltage short-circuit protection, overcurrent protection, high voltage preset, and range adjustment, with a high voltage self discharge time of less than 0.5 seconds.
- 3. It has a self checking function.
- 4. The measurement data is displayed by a three and a half digit LCD digital display, with high accuracy and good reliability.
- 5. During measurement, the range can be pre-set and an audible prompt can be issued for exceeding the range during the measurement process, which is suitable for device grouping and inspection discrimination.
- 6. Choosing continuous measurement allows for uninterrupted testing of batch samples.
- 7. The panel of this intelligent lightning protection component tester has simple functions and is easy to operate.
- 8. Lightweight and easy to carry.
