Electrical Safety Tester: GPT-9804
The GPT-9804 is an electrical safety tester from GW-INSTEK designed for controlled AC and DC withstand tests, as well as insulation and ground bond measurements. The device provides separate test functions for AC withstand, DC withstand, insulation resistance, and ground bond testing according to the specifications provided by the manufacturer.
Features and Measurement Ranges
- AC withstand: output voltage range 0.050 kV ~ 5.000 kV AC, maximum load 200 VA, maximum current up to 40 mA.
- DC withstand: output voltage range 0.050 kV ~ 6.000 kV DC, maximum current up to 10 mA.
- Insulation resistance: test voltage 50 V ~ 1000 V DC, resistance range 1 MΩ ~ 9.500 MΩ with specified measurement accuracies in the datasheet.
- Ground bond: output current range 3.00 A ~ 30.00 A AC, resistance measurement range 10 mΩ ~ 650.0 mΩ, four-terminal test method.
- Standard interfaces: RS-232, USB (device), Signal I/O and front Remote Terminal; GPIB available as an option.
The instrument includes features such as ramp-up (0.1–999.9 s), ARC detect, window comparator, and memory for both manual and automatic test sequences (MANU: 100 blocks, AUTO: 100 blocks). The display is a 240 x 64 dot matrix LCD with backlight, and the power supply accepts AC100V/120V/220V/230V ±10%, 50/60Hz.
