Handling the device The battery test mode Introduction Mode „Battery“ is intended for battery tests by connecting a battery to the load and discharge it definedly. The ave- rage current is measured and the elapsed time is counted and then display as the consumed battery capacity in Ah. The voltage supervision, together with the adjustable un- dervoltage shutdown threshold Ulow, prevents the battery from being deeply discharged.
