Description

Atomfair BT82 Battery Voltage & Internal Resistance Tester

Product Introduction

Atomfair BT82 Battery Voltage & Internal Resistance Tester is a high-precision measuring instrument specifically designed for secondary batteries (lead-acid, nickel-cadmium, nickel-metal hydide, lithium-ion, and lithium-polymer batteries). It enables accurate testing of open-circuit voltage and AC internal resistance of batteries, featuring simple operation, reliable performance, and high cost-performance ratio.

Key Features

• Four-Terminal Measurement Method: Ensures high accuracy and stability of test data.
• Historical Data Viewing: Supports querying previous test results for easy tracking and comparison.
• Comparator Function: Allows setting upper and lower limits (10 groups for both voltage and internal resistance). Enables ON/OFF setting of buzzer alarm; triggers buzzer and red indicator for out-of-limit values, while green indicator signals qualification.
• Large-Capacity Storage: Stores up to 100,000 groups of test data for subsequent analysis and review.
• Multi-Point Calibration: Supports zero calibration (simultaneous calibration of voltage and internal resistance zero points), voltage calibration (external DC 3V~50V reference), and AC internal resistance calibration (10~4000m? precision resistor reference).
• Expanded External Control: Equipped with external control terminals for automated test expansion and optional USB communication (not included in standard configuration).
