BATMASTER allows you to perform in-house testing and re-calibration of RED/GOLD-IBT and GOLD-PLUS intelligent battery testers, simply and quickly, saving you time and money. It is used in conjunction with your own calibrated multimeter and enables you to quickly compare the accuracy between the calibrated multimeter and the battery tester under test. If the battery tester Ah result is low or erratic compared with the multimeter's reading, simply replace the test leads.
