Battery Resistance Tester

Overview

The MT247 is a general rechargeable battery internal resistance tester, Abbreviation: battery internal resistance tester. The MT247 is a measuring instrument used to measure the internal resistance, voltage and temperature of rechargeable batteries such as lead storage batteries, GEL batteries and lithium batteries to determine the health of the battery. It can also be used as a meter to measure the ESR parameters of electrolytic capacitors (for reference only). The meter uses AC 4-terminal test method to measure the internal resistance of the battery and can measure the correct measurement value without being affected by the contact resistance between the test wire, terminal and battery electrode. It also has the functions for data storage, data access, alarm and automatic shutdown. The high grade of the MT247 is a reliable tester with a stable performance has a wide measuring range, high resolution and accuracy, with strong anti-interference ability. The compactness of the meter ensures it is easy to carry to any site, and is an indispensable instrument for battery production, battery installation, equipment production, equipment maintenance and other scenarios. Stored data can be transferred to a PC using an optical USB and software supplied.

Great Lesson for Age 2 and Up
This was our day care's Book of the Month, for children age 2-4 years old. They are all learning to use manners with their peers, at the table and when addressing adults. The lesson took a few readings for the children to understand the point, but once they understood what the various characters WEREN'T doing, therefore getting a negative response from Mr Panda, and what they SHOULD be doing to receive a positive response, the lesson stuck with them. If a child forgets his manners, a hint ("How would you ask Mr Panda?") has good results. This book, while a good story to read aloud, may need some additional explanation by the adult reader at first. Mr Panda offers his friends a treat, and who doesn't like donuts?! When each animal's response is rude or selfish, Mr Panda abruptly withdraws his offer and moves on to someone else. When the final offer is made to a friend who uses his manners, he gets ALL the donuts, because as Mr Panda remarks at the end, he doesn't like donuts anyway. I don't know if this sets up unrealistic expectations, but it's a good lesson presented in an entertaining way.
