To determine in a simple and unequivocal manner whether measurement contacts at which a voltage is to be measured have been properly contacted in a measurement system, in the measurement system, after a discharge switch connecting a charging circuit to a voltage measurement device is closed, the charging circuit is discharged via an internal resistance of the voltage measurement device. When the discharge switch is closed, after a measurement switch connecting the voltage measurement device to the measurement contacts is closed, it is established whether the electrical system is contacted with the measurement system by analyzing the voltage curve at the voltage measurement device after closure of the measurement switch. Advantageously, after the discharge switch is closed, the charging circuit is discharged via a discharge resistor connected in series or in parallel with the voltage measurement device and via the internal resistance.
