Keithley 487 Picoammeter / Voltage Source: 10 fA to 2 mA, 500V Range + IEEE-488

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.

Two displays, one for current readings and one for voltage sourcing, permit the voltage setting and the measured current to be viewed throughout the measurement.

Features and specifications of the Keithley 487 include:

• 10fA sensitivity
• 180 readings per second
• IEEE-488 interface
• Resistivity measurements (<1O to >10¹⁶O)
• ± 500V source
• 10fA sensitivity
• 180 readings per second
• IEEE-488 interface

The 5-1/2 digit Model 6485 Picoammeter combines Keithley's expertise in sensitive current measurement instrumentation with enhanced speed and a robust design. With eight current measurement ranges and high speed autoranging, this cost-effective instrument can measure currents from 20fA to 20mA, taking measurements at speeds up to 1000 readings per second
