Overview
About GDM-8245 Dual Display Digital Multimeter
The GDM-8245 is a 50,000-count dual display benchtop digital multimeter designed for production test and R&D bench applications. Dual display capability allows simultaneous measurement of two parameters, for example, ACV and frequency, or DCV and ACV, without switching modes.
Multi-function measurement covers ACV, DCV, ACA, DCA, resistance, capacitance, frequency, diode test, and continuity. 0.03% DCV basic accuracy meets calibration-grade requirements. ACV measurement bandwidth extends to 50 kHz for power supply and audio frequency testing.
AC True RMS measurement handles both AC and AC+DC coupled signals, providing accurate readings on distorted waveforms from switching power supplies and motor drives. Manual and auto-ranging modes accommodate both precision bench work and quick field measurements.

Battery Simulator vs Battery Emulator: Hardware for BMS and Pack Testing
The bench instrument whose terminals behave like a battery pack, why a plain DC supply leaves BMS code paths unexercised, and the capability list to specify against. Worked through the GW Instek RBS Series battery simulation function.
BESS Test Benches: Rack-Level Charge and Discharge Qualification
The bench that qualifies a storage rack: which voltage classes rack buses land in, the current envelope at top of charge, parallel growth in the class you buy first, and cycling that runs unattended for weeks.
Motor Drive Test Benches: DC Bus Supply and Regenerative Braking
A motor drive bench powered at its DC link terminals needs a bus that supplies the drive and takes energy back when the motor brakes. How one bidirectional source, sized against the real bus voltage, replaces the supply, blocking diode and load.
