Megger BITE 2P Battery Impedance Test Set is designed to identify the condition of lead-acid and nickel-cadmium cells up to 7000 Ah, and includes an advanced feature set that provides Pass/Warning/Fail calculations based on a user-entered baseline value. Megger BITE 2P Battery Impedance Test Set also includes advanced printing functions; there is a built-in printer to review the active test and allow the user to leave a hard copy record at the site.
The Megger BITE 2P Battery Impedance Test Set works by applying a test current across the battery string while on-line, then measuring the total current and the voltage drop of each cell/jar. The Megger BITE 2P Battery Impedance Test Set then calculates the impedance, also measuring 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.
Unlike the substantial downtime and repeated discharges encountered with load cycle testing, the Megger BITE 2P Battery Impedance Test Set requires no battery discharge nor is there any stress on the battery. A test time of less than 20 seconds for each cell and intercell connector ensures that one person can quickly and easily measure internal cell impedance, dc terminal voltage and intercell connection resistance without taking the battery system off line.
