| The dye was iontophoretically injected by current pulses of short duration, generated by the electrometer. |
| The use of an electrometer or galvanoscope for sensing magnetic field or electric fields are well known. |
| The electrodes from each specimen measured were connected to an electrometer, which in turn was connected to a Pentium PC, which yielded a printout of the measurement. |
| Electrostatic methods are normally used, such as the field mill, which measures induced electric charge, or an ultra-high-impedance electrometer voltmeter. |
| Hertz generated cathode rays inside an apparatus that included an electrometer to measure the electrical charge of the rays. |
| Voltage output from the electrometer was sent to a chart recorder and collected on computer disk via a data acquisition system. |
