Description
Product Overview
The HS-BT is a high-precision instrument specifically designed for testing both primary and secondary batteries, including lead-acid, lithium iron phosphate, lithium cobalt oxide, lithium manganate, lithium-ion, and lithium polymer batteries. It measures battery open-circuit voltage and AC internal resistance with high reliability and user-friendly operation, offering excellent performance-to-cost ratio.
Key Features
- Data Storage: Stores up to 100,000 sets of test data
- Calibration Functions:
- Zero-Voltage Calibration: Simultaneously calibrate battery voltage and internal resistance zero points
- DC Voltage Calibration: External voltage input (DC 3V–50V, adjustable) for standard voltage calibration
- AC Resistance Calibration: External resistance input (10–4000 mΩ, adjustable) for internal resistance calibration
- External Interface Expansion: Optional PC control and USB communication (USB module not included by default)
