TES-32A - battery capacity tester

TES-32A is designed to measure the internal resistance and voltage at the open-circuit terminals of nickel-metal hydride (NiMH), nickel-cadmium (NiCd), lithium-ion (Li-ion), alkaline, and lead-acid batteries.
The AC internal resistance measurement is performed using the four-wire method and includes a compensation function (zeroing the readings) for the test lead resistance to eliminate the influence of the test lead resistance on the measurement result.
The dual LCD display allows for simultaneous measurement and reading of internal resistance and voltage.
Measurement results can be compared with the minimum and maximum allowable limits of internal resistance and constant reference voltage programmed in the comparator, allowing for a quick assessment of the condition of the tested battery (good, relatively good, poor).
The tester can save 500 sets of data in memory during manual recording and up to 9,600 sets of data using continuous recording (logging). This data can be transferred to a PC.
