The Keithley 487 is designed for measurement of low currents and very high resistances. The 487 incorporates all the capabilities of the 486, and adds a programmable 500 V 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 10 fA to 2 mA. Two voltage source ranges are available: a 500 V range with 10 mV resolution and a 50 V range with 1m V resolution.
A PRESET button allows the user to toggle between two separate source values.
The 487 sources up to 500 V, measures the current with 10 fA sensitivity, and then instantly calculates the resistance value, from 500 Mohms to 5x10 E16 Ohms.
The 487 displays either current or resistance. Reading intervals from 10 ms to 1000 s can be programmed, simplifying tests that require a predetermined soak time.
