The Keithly 487 Picoammeter / Voltage Source was built for measurement of low currents and very high resistances. The 485 incorporates all the capabilities of the Keithley 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 Keithley 487 makes cur measurements from 10 fA to 2 mA. Two voltage source ranges are available: a 500V range with 10mV resolution and a 50V range with 1mV resolution. A PRESET button allows the user to toggle between two separate source values. The 487 sources up to 500V, measures the cur with 10fA sensitivity, and then instantly calculates the resistance value, from 500mO to 5 × 1016O. The 487 displays either cur or resistance. Reading intervals from 10ms to 1000s can be programmed, simplifying tests that require a predetermined €œsoak " time.
Two displays, one for cur readings and one for voltage sourcing, permit the voltage setting and the measured cur to be viewed throughout the measurement.
Features and specifications of the Keithley 487 include:
