ZX-NZY02 Internal Resistance Tester Tech Overview

The ZX-NZY02 Storage Battery Internal Resistance Tester represents a sophisticated, portable instrument designed for comprehensive maintenance and analysis of battery systems. This technical overview details its capabilities, specifications, and operational design for engineering and technical personnel.

Core Functional Capabilities
The tester integrates multiple diagnostic functions into a single platform. Its primary role is the precise measurement of battery voltage, internal resistance, and connection resistance. It can also operate as a standalone voltmeter for individual cell voltage checks. A key feature is its automatic identification of battery voltage levels, streamlining the testing process across different battery types (e.g., 2V, 6V, 12V cells). Furthermore, the instrument provides a capacity estimation function, offering valuable insights into battery health and remaining useful life.

Intelligent Features & Data Management
      Beyond basic measurements, the ZX-NZY02 enhances diagnostic efficiency with several intelligent features. It includes a built-in reference table for internal resistance, allowing for immediate comparative analysis. User alerts are delivered via both on-screen text messages and a buzzer for results or fault conditions. For organized data collection, it supports storing measurements in battery pack mode, enabling users to review data for entire banks and individual cells seamlessly. The unit facilitates detailed record-keeping by allowing input for site names and group numbers in English.

Technical Specifications & Performance
The instrument delivers high-precision measurements across critical parameters:

1.Voltage: 0-15V range with a resolution of 0.001V.

2.Internal Resistance: 0-100 mΩ with a resolution of 1μΩ.

3.Connection Resistance: 0-2 mΩ with a resolution of 1μΩ.

4.Temperature: Measurement capability from -20℃ to 80℃.

It boasts substantial data storage capacity, capable of holding 999 measurements per individual cell. For system-wide analysis, it can store data for up to 18 complete battery groups (calculated at 104 cells per group), with a total storage capacity of 512kB.

Power System & Environmental Robustness
Powered by an integrated 12V, 3000mAh rechargeable lithium battery, the device is engineered for extended field use. It offers a standby time exceeding 32 hours (with auto-standby enabled) and continuous operation for no less than 6 hours. The lithium battery charge status is clearly indicated. An automatic shutdown function activates after 10 minutes of inactivity to conserve power.

The tester is built for demanding environments, with an operating temperature range of 0°C to 40°C and a broader storage temperature range of -20°C to 60°C. It can function in relative humidity from 10% to 90%. Its portable form factor measures 238 x 134 x 45 mm.

Summary
The ZX-NZY02 is a robust, feature-rich diagnostic tool that combines precision measurement, intelligent analysis aids, and extensive data management. Its design prioritizes field usability, offering long battery life, clear operational feedback, and resilience in various environmental conditions. For technical professionals, it provides a comprehensive solution for predictive maintenance, fault diagnosis, and performance assessment of stationary battery installations.
