Any error signals that remain are negligible in comparison to those that can occur when measuring current with a DMM. DMMs measure current using a shunt resistance that develops a voltage typically mV full-range in the input circuit. The builds on the features and capabilities of the Keithley electrometers keith,ey preceded it.

The lowers this terminal voltage still further-to the level of the voltage noise-by canceling out the small offset voltage that remains.

The instrument’s sensitivity makes it easy to determine the leakage resistance on capacitances up to 10nF or even on higher capacitances when a series resistor is used. The instrument also allows active cancellation of its input voltage and current offsets, either manually via the front panel controls or over the bus with IEEE commands.

A normal-mode rejection ratio NMRR of 60dB allows making accurate low current measurements, even in the presence of line frequency induced currents, which is a common concern in production floor environments. The instrument’s interfaces also simplify integrating external hardware, such as sources, switching systems, or other instruments, into the test kkeithley.

Main PCBtop and bottom view. Typically, offset currents in DMMs are tens or hundreds of picoamps, which severely limits their low current measuring capabilities compared to the with 3fA input bias current.

They usually have voltage, current, resistance and charge measurement functionality, just like usual DMMbut can do these measurements with minimal loading on the circuit under test. These instruments usually have special low-leakage shielded input connectors, often with keitlhey design with PTFE insulators. For example, like those instruments, a built-in constant current source simplifies measuring resistance.

Equipment used during restoration project: Model Image 8: Applications include measuring currents from light detectors and other sensors, beam experiments, and measuring resistances using a current source.

Economical Component Testing Once, electrometers were simply considered too slow to keep up with the high throughput that production test applications demand. In a similar manner, offset currents can also be cancelled. Model Image 9: In addition to use by researchers in areas such as physics, optics, and materials science, the ‘s affordable price makes it an attractive alternative to high end DMMs for low current measurement applications, such as testing resistance and leakage current in switches, relays, and other components.

Bulk capacitors are listed in table below: A similar circuit used also as a I-to-V converter, to allow electrometer to measure currents down with 10 A femtoamperes or 0.
