Electrical Safety Tester — GPT-9803
What it is and what it does
The GPT-9803 from GW-INSTEK is an electrical safety tester in the GPT-9800 series, designed to perform AC and DC withstand voltage tests as well as insulation resistance measurements. The device can generate controlled test voltages for both AC and DC and measures corresponding current and resistance values within the specified measurement ranges.Features and operation
As a technical tester, I briefly explain the verified functions, as shown in the manufacturer's specifications:- AC withstand voltage: 0.050 kV to 5.000 kV.
- DC withstand voltage: 0.050 kV to 6.000 kV.
- Insulation resistance tests with test voltages from 50 V to 1000 V DC.
- Measurement of current and resistance within the specified ranges in the datasheet.
- Selectable mains frequency for AC output: 50 Hz / 60 Hz.
