MECO introduces battery capacity (impedence) tester- model 6363. Its features include: memory and read function, knows true life of battery capacity (resistance/ voltage); on-line testing, rates condition as pass, warning or fail; compact, light weight and consists dual display; 99 sets of composite comparator function, which can be set at impedance and voltage values to get the reliable values to get the reliable detection of battery deterioration; AC 4-terminal pin type leads, which can easily contact the battery electrodes; manual datalogging (999 datasets); designed for measuring the internal impedance and open circuit voltage of the secondary battery including Nickel-metal hydride battery (NiMH), Nickel cadmium battery (NiCd), Lithium-ion battery (Li-ion), Alkaline battery and Lead-Acid battery. Can measure resistance from 4mv to 40? with minimum resolution of 1µm. Voltage measured is up to 40V with resolution up to 10mV. It operates in an environment from 0ºC to 40ºC. Its maximum input voltage is 50V DC.
