Connection with 1.2V or 2V cells:
Connection with 6V or 12V cells:
DAC is optional for wireless communication with K-3980 main unit and PC. The new insulation-protected DAC is rugged and capable to measure all type of batteries (1.2V, 2V, 6V and 12V).
Its Connection:
One DAC could be connected with 12 cells of 1.2V, 2V or 4 cells of 12V (or 6V). Therefore, in different battery systems, they require different amount of DACs. With DAC, K-3980 and Kongter PC software will be able to monitor and record voltage of each cell together with other parameter like String Voltage, Current, Discharge Capacity and so on.
