Product Overview
GW‑INSTEK GCT-9040 — AC ground bond tester
The GCT-9040 from GW‑INSTEK is an AC ground bond tester designed to measure ground bond resistance using AC test current. The instrument specifies a maximum AC test current of 40 A and measures resistance in the range of 1 mΩ to 650 mΩ. The GCT-9040 uses a PWM switching amplifier architecture and provides measurement and control functions via the front panel and external interfaces.
Functionality and Design
The GCT-9040 performs ground bond tests by supplying a controlled AC current and measuring the resulting resistance. The unit features a 240 x 64 ice-blue dot-matrix LCD for displaying measurement values and settings. The front panel includes a REMOTE terminal for starting/stopping test cycles, and the instrument can store up to 100 memory blocks with test conditions.
