+Messwert per Tastendruck erfasst (time,tempReservoir,ECadcCalib,ECadc,ECadcAdjusted)
+	zeit
+	temperatur d. flüssigkeit
+	referenz adc wert (geschalteter fester widerstand statt probe)
+	Roher ADC Messwert (Probe A)
+	angepasster ADC Messwert (linear gemappt nach abweichung vom referenz adc wert, referenz adc wert vorher ermittelt und eingegeben in code)  (Probe A)
