• Determines condition of lead-acid and NiCd cells up to 7000 Ah • On-board Pass/Warning/Fail indications • Robust, repeatable instruments • On-line testing • Checks charger condition by measuring AC ripple current • Includes PowerDB LITE Software The BITE2 and BITE2P battery impedance testers determine 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 BITE2P consists of both a transmitter and a carrying case for all standard accessories and some optional accessories. The BITE2 and its accessories fit into a sturdy canvas case with a shoulder strap. The instruments work by applying a test current across the battery string while on-line, then measuring the total current (AC ripple and test current) and the voltage drop of each cell/jar. It then calculates the impedance. They 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. The BITE2 and BITE2P receiver stores the readings in its internal memory. These measurements, along with other maintenance data such as ambient and pilot cell temperatures and AC ripple current, assist in determining the overall condition of battery systems. Megger recommends that impedance measurements with the BITE2 or BITE2P be made part of a battery maintenance program with readings taken and recorded semi-annually for flooded batteries and quarterly for VRLA.
