TES-32 Battery Capacity Tester can measure the internal resistance and open circuit voltage of lead-acid batteries, nickel-cadmium batteries, lithium batteries and nickel-hydrogen batteries.
The TES-32 battery capacity tester measures internal resistance and open‑circuit voltage of rechargeable batteries such as lead‑acid, Ni‑Cd, Li‑ion and Ni‑MH. It uses an AC four‑terminal method for high‑accuracy resistance measurement and provides dual LCD and LED displays for simultaneous resistance and voltage readout. Up to 99 comparator sets can be stored to monitor battery aging.
The guide covers preparation, step‑by‑step usage, zero‑adjustment, comparator configuration, data‑recording (manual up to 999 entries, continuous up to 6000), and maintenance procedures including battery replacement and cleaning. Safety warnings and environmental limits are also provided. This manual is written in Chinese.
