■ DC withstanding voltage test 5kV/10mA（TH9320/A）5kV/5mA(TH9310/A)
TH9310/20 series can provide DC withstanding voltage test of wide voltage range (Max. output
DC is 6kV). The automatic voltage regulation and voltage load regulation of 600Hz frequency
hardware is less than 1%+10V.

■ Insulation resistance test 0.050kV to 1.000kV（resolution of 1V）/0.1MΩ to 10.0GΩ (Max.
rated current of TH9320 is 10mA and max. rated current of TH9310 is 5mA)
Insulation resistance test range:
Voltage ＜ 500V: 0.1MΩ to 1GΩ accuracy：± [10% reading +5 digits]
Voltage ＞ 500V: 0.1MΩ to 100MΩ accuracy：[5% reading +5 digits]
100MΩ to 1GΩ accuracy：[10% reading +5 digits]
