Trek 820 High Impedance Contacting_Non-contacting Voltmeter - Manual

® The ±2 kV Trek Model 820 Infinitron Voltmeter may be
used in either contacting or non-contacting mode to
acquire precision surface voltage measurements. It is
especially beneficial when used with applications that
demand infinitely high loading impedance levels far
beyond the reach of currently available high impedance
voltmeter instruments. The Model 820 comes with a
guarantee of virtually no modification of the object being
measured. This allows the instrument to indicate, with
high precision, the voltage level of both conductive and
insulative objects and surfaces.
