Product Overview
The GPT-9801 is an electrical safety tester (HiPot) from GW-INSTEK, designed for AC withstand voltage testing. The instrument delivers AC output voltage from 0.050 kV to 5.000 kV and is engineered for controlled withstand voltage tests with both manual and automatic operation.Key Features
- PWM amplifier platform and 240 x 64 dot-matrix LCD display.
- AC output range 0.050 kV~5.000 kV with 2 V resolution and sinusoidal output.
- High resolution in current measurement (best resolution 0.001 mA) and ARC detection.
- Controllable ramp-up time (0.1–999.9 s), test timer (OFF / 0.5–999.9 s), and automatic discharge of DUT after each test.
- Front-panel remote terminal as well as standard interfaces: RS-232, USB (device). Optional GPIB.
- Memory for test conditions: up to 100 blocks in manual mode and up to 100 blocks in automatic mode.
Operation and Measurements
The GPT-9801 measures AC current in the range of 0.001 mA to 40.0 mA with multiple resolution options (0.001/0.01/0.1 mA). Frequency control (50 Hz / 60 Hz) and voltage regulation are specified in the manufacturer's technical data. The instrument supports both window comparator method and ARC detection for test control.
