The Megger BITE 2P Battery Impedance Test Set determines the condition of lead-acid and nickel-cadmium cells up to 7000 Ah.
An advanced feature set has been developed that includes Pass/Warning/Fail calculations based on a user-entered baseline value, advanced printing functions and more.
The case of the Megger BITE 2P consists of both the transmitter and a carrying case for all of the standard accessories and some of the optional accessories, in an all-in-one unit.
The instrument works by applying a test signal across the battery string while on-line, then calculates impedance based on simultaneous measurements of current and resulting voltage drop of each cell/jar.
The Megger BITE 2P also measure dc voltage and interconnection (strap) resistance to help determine the overall condition of the entire battery string’s electrical path from terminal plate to terminal plate.
