Waterproof, dustproof.
Adhesive digital voltmeter (voltage meter), with green LED display
Measuring range: approx 9-16 V (outside of this, it flashes)
Parameters: 6 x 3 x 2 cm
Wire length: 90 cm
Important: connect the voltmeter to a place on the motorcycle where there is voltage only when the ignition is switched on, otherwise the voltage display will drain the battery within weeks (e.g. winter). However, it is good to know that the charging voltage measured on the ignition-switched wire is slightly lower than the actual, real charging (compared to the battery)!
