Keithley Series 6400 Picoammeters

Keithley Series 6400 Picoammeters

The cost-effective 5½-digit Model 6485 Picoammeter can measure currents from 10fA to 20mA, at speeds up to 1000 readings per second. The Model 6487 Picoammeter/Voltage provides higher accuracy and faster rise times than the 6485, a 500V source, and a damping function for use with capacitive devices. The Model 6482 Dual-Channel Picoammeter/Voltage Source offers higher measurement resolution than the Model 6485 or Model 6487 and dual, independent 30V voltage bias sources.

Keithley Series 6400 Picoammeters

Features

Benefits

Current resolution as low as 1fA (6482) Allows measuring ultra-low leakage currents in components, dark currents in optical devices, and beam currents in microscopy instrumentation.
Burden voltage as low as 200μV Allows making current measurements with high accuracy, even in circuits with very low source voltages.
Dual-channel measurements (6482) Simplifies analyzing multi-channel devices, monitoring currents in multiple locations on materials, and recording data from multiple sensors at once.
Choose from 0, 1, or 2 built-in voltage sources Ensures you can find the voltage bias capabilities your application demands. Perform insulation resistance testing with the 500V source in the Model 6487 Picoammeter /Voltage Source.
Built-in analog outputs Allows transmitting measurement results to devices like DMMs, data acquisition boards, oscilloscopes, or strip chart recorders for signal response and trend analysis.
Measure currents up to 20mA Supports measuring currents high enough for applications such as measuring 4-20mA sensor loops.
Up to 1,000 readings per second Offers the high throughput production testing demands.
Built-in Trigger Link interface Simplifies synchronizing with other instruments and voltage sources by combining six independent selectable trigger lines on a single connector for simple, direct control over all instruments in a system.

Resistivity Measurement with 8009
Model 6487 is a picoammeter with a voltage source. It acts like the 6517B for the resistivity measurement but does not calculate the resistivity, only resistance. So it will source the voltage and measure the current, then calculate the resistance. You…
