Overview
About GDM-9041/9042 Series
The GDM-9041/9042 Series offers 50,000 counts resolution with 0.02% basic DCV accuracy and AI measurement technology for automatic identification of voltage, resistance, diode, and continuity modes. The 4.3” TFT graphic LCD provides clear readout with graphical display capabilities. Both models cover 11 measurement functions and support comprehensive math operations including max/min, REL, MX+B, 1/X, Ref%, compare, hold, dB, and dBm.
Model Comparison
| Feature | GDM-9042 | GDM-9041 |
|---|---|---|
| Display Resolution | 50,000 counts | 50,000 counts |
| DCV Basic Accuracy | 0.02% | 0.02% |
| AI Measurement | Yes | Yes |
| Temperature Measurement | Yes | No |
| USB Storage (Data Collection) | Yes | No |
| Optional GPIB (Factory Install) | Yes | No |
| USB Device (CDC & TMC) | Yes | Yes |
The GDM-9042 adds temperature measurement capability, USB storage for onboard data collection, and an optional factory-installed GPIB interface for integration into automated test systems. The GDM-9041 provides the same core measurement accuracy without the extended features, making it a cost-effective choice for standard bench applications.
Applications
Production lines, quality assurance labs, and field service teams benefit from the AI measurement mode that reduces setup time and operator error. The USB storage on the GDM-9042 enables standalone data logging without a connected PC, which is valuable for long-duration monitoring and trend analysis.
GSAS Micro Systems supplies the GDM-9041/9042 Series across India with technical consultation, calibration services, and local inventory 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.
