Keithley 487
Picoammeter/Voltage Source 500V
Description
This Picoammeter is designed for measurement of low currents and very high resistances.
This instrument incorporates all the capabilities of the 486, and adds a programmable 500V source.
This combination of picoammeter and voltage source provides a powerful high resistance meter and fast picoammeter in one instrument.
The 487 makes current measurements from 10fA to 2mA.
Two voltage source ranges are 500V range with 10mV resolution and a 50V range with 1mV resolution.
Key Points
Resistivity measurements from <1Ω to >1016Ω
± 500V source
10fA sensitivity
80 readings per second
IEEE-488 interface
