• 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. CTII31 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.
