F] is the feedback impedance of the coulombmeter Input noise is the noise of the input stage of the electrometer
This is just the beginning," says Roukes, who sees the electrometer
as a demonstration of what an integrated microelectromechanical system can do (SN: 7/26/97, p.
FIGURE 1 illustrates a basic configuration for measuring capacitance with an electrometer
with an internal voltage source.
The induced currents for intact and attrited PVC samples in the horizontal pipe segment were similarly measured using the Electrometer
How to Enable the Meter Connect Feature on the Model 6517B Electrometer
Measurements were obtained with a home-made sample holder (described in ASTM D-257) coupled with a Keithley 6517-B electrometer
The use of the ratio to radium mitigates uncertainties caused by variations in the electrometer
response over time.
Membrane potentials were measured by impaling root cells with a conventional microelectrode connected to a high-impedance electrometer
(Electro 705; WPI, Sarasota, FL) and digitally recorded (DUO 18; WPI, Sarasota, FL).
s] by using a digital electrometer
(Keithely 614) and a micro-voltmeter (197A, Keithley), and the value of [[rho].
This is the maximum voltage allowed by the electrometer
owned by the KEBS.
