Features
- Adopting switching power supply principle, max constant current output 1.8mA and voltage output range 25~1000V,with step 1V
- High test speed, minimum test cycle only 50mS
- Unique anomaly detection function, the instrument can detect the test leads abnormality and the abnormal contact of the measured object, avoiding the open circuit misjudgment
- Short-circuit detection function effectively detect short-circuit conditions and avoid
- Direct application of high-voltage breakdown of defective products and to misjudgment
- Automatic discharge, the instrument will automatic discharge after the test completed. HT9920 adopts non-contact constant current discharge, fast, efficient and reliable
- Various interfaces are equipped, external I/O, analog, LAN ,RS232 interface
- Double-click trigger to prevent high-voltage electronic shock accidents caused by false triggers. Users can set the double-click action to trigger the test.
- Analog output. Analog output port of the instrument output results. After each test is completed, output 0~4V analog voltage value corresponding to the test result. There are two types of voltage output, one is full range output and the other is single range output.
- Quickly charge and discharge the capacitive load
- Stable measurement without additional shielded wire.
- Parts of the device under test contact check function to avoid misjudgment in open circuit.
- Short circuit detection before test to prevent high voltage breakdown.
- Continuous test mode, PASS termination mode, FAIL termination mode, and forced termination mode.
- Various interfaces, suitable for pipeline sorting.
