The Megger 246201 bar code wand with preprinted code sheet transmits header and cell data to the Megger BITE 2 and BITE 2P battery impedance testers. It comes with a preprinted, laminated code sheet that has alphanumeric bar codes and commands, such as “enter,” for quick scanning. The bar code wand scans a barcode on the battery string to identify it, reducing the time it takes to enter battery information into the BITE2 or 2P system. The bar code wand measures 5.98 x 2.84 x 0.866 inches (152 x 72 x 22 mm, H x W x D, where H is height, the vertical distance from the lowest to highest point; W is width, the horizontal distance from left to right; and D is depth, the horizontal distance from front to back), and it weighs 2.89 oz. (81.36 g).

Battery testers are used in the industrial, commercial, medical, telecommunications, aircraft, power utility, and military industries to detect the health of a battery. They can measure conductance, impedance, voltage, and current, among other parameters. Battery testers are designed for specific types of batteries, such as lead-acid, nickel-metal-hydride (NiMH) and alkaline batteries. Some testers require a load to be applied to the battery during testing, and some do not. A variety of test leads with contacts, probes, clamps, clips, and other connectors can be used to connect a battery to a tester. Since different testers can measure different parameters to calculate battery health, it is important to use the same tester for consecutive tests on a single battery when analyzing changes in battery health over time.
