To Control Ionization. 1  Ionization Voltage Typically, 70eV electrons from the filament are used for EI. 2  Emission Current The number of ions produced in unit time is proportional to the current of emitted electrons, i.e., emission current. 3  Ion Source Temperature The ion source is usually used at about 200 oC.
Arduino Capacitance Meter Theory. Capacitance is a measure of the ability of something to store electrical charge. Each Arduino capacitance meter relies on the same basic property of capacitors-the time constant.The time constant of a capacitor is defined as the time it takes for the voltage across the capacitor to reach 63.2% of its voltage when fully charged.he Arduino measures the capacitance of the unknown capacitor by recording the time it takes for the capacitor to reach 63.2% of its voltage when fully charged, then dividing that value by the known resistance of the circuit.
