Battery Impedance Tester | Battery Test | BITE 3
The Megger BITE 3 battery impedance tester determines the condition of lead-acid cells up to 2,000 amp-hours by measuring key battery parameters. The BITE 3 measures cell impedance, cell voltage and cell junction resistance and performs an internal ohmic test. In addition, for the first time in such an instrument, the BITE 3 battery impedance tester measures trickle charge current and superimposed AC current. There is even a built-in spectrum analyzer to display the harmonic content of the AC current. The instrument includes firmware that can be updated using the Internet and supports a variety of languages. The BITE 3 is one of the easiest devices to use. It works by measuring the internal impedance of cells, cell junction resistance, cell voltage, and trickle charge current and ripple current.
These quantities, along with temperature, specific gravity, and other battery data, provide the best means of evaluating the overall condition of the batteries from terminal plate to terminal plate, and to some extent the charger (the superimposed AC current and its harmonic content.) Megger recommends that the BITE 3 be one of the elements of a comprehensive battery maintenance program in which, for lead-acid cells, semi-annual and for VRLA, quarterly
for lead-acid cells and quarterly for VRLA. The BITE 3 is one of the easiest instruments to use.
It operates by measuring cell internal impedance, cell junction resistance, cell voltage, and float charge current and ripple current. These quantities, along with temperature, specific gravity and other battery data, provide the best means of evaluating the overall condition of the batteries. To some extent, also the charger (the superimposed AC current and its harmonic content.) Megger recommends making the BITE 3 one of the elements of a comprehensive battery maintenance program.
