Applications
Field service engineers and maintenance technicians use the GDM-541 and GDM-533 for on-site electrical troubleshooting where true RMS accuracy on non-sinusoidal waveforms matters. The GDM-532 offers resolution at 9,999 counts with temperature capability for HVAC and industrial maintenance. The GDM-531 provides essential measurement functions at an economical price point for basic electrical testing.
The USB interface on the GDM-541 enables data logging and PC-based analysis, supporting documentation requirements in regulated maintenance and calibration workflows.
GSAS Micro Systems supplies the complete GDM-500 Series across India with local stock availability, competitive pricing, and after-sales support.

GW Instek Insights
Emulating Processor Power for Thermal Testing: Why Constant Power
A heat sink or a cold plate is qualified against a watt figure, not a volt figure. This application note explains why a thermal load is driven in constant-power mode, how the bench is built for air and for liquid cooling, and what to confirm before you buy.
CRPS and Rack Power Supply Testing: The Six Tests That Matter
A CRPS module has to hold up under an unbalanced grid, a 0 to 100 percent load step, a surge on the line and a redundancy handover. This application note sets out the six tests, and the one source capability that makes a long feeder reproducible on the bench.
GPU Power Board Testing: DC Input Verification Before Integration
A GPU power delivery board is cheap to reject on a bench and expensive to find in an assembled server. This application note covers the programmable DC input test that screens the board, and the same test applied to incoming server systems.
