Calibration and Traceability: To maintain measurement accuracy, DC Resistance Meters require periodic calibration. Calibration ensures that the meter provides accurate resistance measurements within specified tolerances. Calibrated meters are traceable to national or international standards, providing confidence in the accuracy and reliability of the measurements.
Features
Multiple test functions
4-terminal test, the test can’t be influenced by impedance of test leads.
Contact inspection, to inspect the contact of test leads in testing
Deviation deduction (rel) and reference operation, eliminate the influence of base to test result.

Brief Introduction
As the growth of electronic products, cell phone, home appliances, electric vehicle and bike emerge in an endless stream, all need to work with battery, so the fast inspection on batter will influence the performance of products.
With Tonghui’s experience in impedance test and marketing survey, the new battery tester-TH2523 is successfully launched.It can be competitive with other similar products with its outstanding performance, easy operation and new look.
1kHz constant current source is adopted to eliminate the potential error of thermoelectric force to DUT.
Max.300V(TH2523A) test voltage can meet the demand of high voltage battery
0.1% basic resistance accuracy, the range of 30m-3000 can cover the test demand of large battery pack to button battery,and as well for large type but low resistance lithium battery
The fast test speed can up to 20ms/time
Meet the demand of ACR test for general components.
TH2523 provides multiple interfaces, which is for PC communication and remote control.
Application
Fast test for button battery and battery pack .etc.
For cell phone, home appliances,electric vehicle and bike .etc.
For high voltage battery test
For early battery R&D test
Contact resistance test
Degradation and lifetime-evaluation of battery
UPS on-line test
ESR test of super capactitor
