High current consumption in battery-operated devices leads to an undesirably rapid discharge of the 9V block. Checking the current consumption without this measuring adapter used to be time-consuming and costly. The VOLTCRAFT MB-703 measuring adapter is connected to the battery contact at the front and to the 9V block at the rear. The measuring adapter is compatible with all standard digital multimeters thanks to the 4 mm blade connectors. This adapter can be used to measure both the operating current and the battery voltage under load. Special feature: straight.
