BRS BIM1 User Manual

1 Overview
1.1 Short description
The BIM1/BIM2/BTC1/BIM300 are economical, easy to
operate and compact battery impedance measuring in-
struments.
They offer functions of a battery tester, of a battery ana-
lyser and a capacity tester and enable the quick test of
batteries and accumulators.
They are connected in parallel to the battery terminals
and measure the complex battery impedance and voltage of cells or modules inde-
pendently of the battery technology. Some versions offer additional temperature and
current measurements.
The measurement values are provided in an electrically isolated manner via a USB
communication interface. The device is operated with a graphical user interface
(GUI) and the results are shown on this interface. Alternatively, there is a program-
ming interface for remote control.
