I.Overview

As a key component of the power supply system, the battery must be tested and maintained every year, every quarter or even every month, and its test data needs to be analyzed on a regular basis.

At present, the maintenance of valve-regulated lead-acid batteries in China is generally to check the float voltage of the battery. Practice has proved that there is no correlation between the voltage and the capacity, because the voltage only reflects the surface parameters of the battery.

Internationally, the conductivity or internal resistance test has been widely used in the daily maintenance of batteries to replace the voltage inspection method in the past. Because the conductance or internal resistance is a parameter that reflects the internal battery, the conductance or internal resistance of the battery has been recognized as an important parameter for accurately and quickly judging the health of the battery.

The battery conductance or internal resistance tester is a digital storage type multifunctional portable tester for quickly and accurately measuring battery operating parameters. The meter can display and record important battery parameters such as battery voltage, conductance or internal resistance, connecting strip resistance, etc., through online testing, and accurately and effectively judge the battery's good condition. It can form an intelligent test with a computer and special battery data analysis software. Equipment, further track the decay trend of the battery, and give an alarm in advance to facilitate the discretionary processing of engineering and management personnel.

II.Main functions and features

The main function

1. Quickly measure the battery's voltage, conductance or internal resistance, connection resistance and other parameters online.

2. Alarm for battery conductance or internal resistance and voltage exceeding limit.

3. The meter adopts anti-AC ripple noise circuit technology to make the meter test results more accurate and the test results more consistent.

4. The meter has a quick re-test function. If human error is found during the test, it can be re-tested and automatically overwrite the original data.

5. The meter prestores more than 200 reference conductance or internal resistance values, which can also be customized.

6. The battery parameters are all numbered in groups, which is convenient for data management.

7. Supporting powerful computer battery status intelligent analysis software to realize the tracking and analysis of battery "medical records".

8. The automatic test mode is convenient for users to measure.

(1) Automatically analyze and judge the "deteriorated" state of the battery.

(2) Form a historical record database to describe the battery status curve.

(3) Comparative analysis of the same group of batteries.

(4) All battery classification management (good, medium and poor)
