YD9880 series programmable safety comprehensive testerDetailed product description：

The YD9880 series programmable safety comprehensive tester has self calibration and self diagnostic functions for comprehensive parameter testing of voltage resistance, insulation, grounding, leakage, power, and low voltage startup. It has a standardized operation interface and uses a 240 × 128 LCD display for easy operation

The test mode can be set arbitrarily, with 50 memory groups and multiple test parameter settings for each group. Continuous testing can be set at once
Hot state leakage test, meaning setting the voltage rise time, can analyze the breakdown point

YD9880 series programmable safety comprehensive tester can be optionally equipped with PLC interface and RS232 interface
