The battery internal resistance tester can measure internal resistance and voltage of the battery at the same time. The Kelvin four-wire test clamp is adapted in order to better avoid the influence of contact resistance and wire resistance, and more accurate measurement can be performed

This product adopts intelligent contrl, liquid crystal display, and simultaneous insertion of Kalman flter mathematical algorithm, which has the advantages of high precision, high eficiency, low cost, light weight, energy saving and environmental protection. Built-in 2000mAh lithium battery,5V charging. mobile phone charger can be used, which is very convenient.

1. Common basic operations
For common users, click enter to start the machine, use the probe (or clip) to contact the positive and negative electrodes of the battery to be measured, and the device will automatically switch the appropriate gear for accurate measurement, with voltage (1-100v DC) and internal resistance of 0.1M Ω- two hundred Ω It can be measured normally; If you don’t want to use it, press and hold the Enter key for 2 seconds, and the device will shut down;

If the user enters into other menus and cannot measure, just press the menu key twice to return to the main measurement menu for measurement;
2. The machine can’t input DC voltage greater than 100V, and can’t input AC voltage under any condition. The charging port uses micro USB charging port, and input 5V
