ETYM Electro- + -meter: cf. French électromčtre.
Measures electrostatic voltage differences; draws no current from the source.
A highly refined DC multimeter. In comparison with a digital multimeter, an electrometer is characterized by higher input resistance and greater sensitivity. It can also have functions not generally available on DMMs (e.g., measuring electrical charge).
Instrument for measuring electrical potential.
Instrument measuring differences of electrical potential.
Instrument za merenje razlika elektrostatičkog potencijala; up. elektroskop.
