Used KEITHLEY 487 #9201228 for sale

KEITHLEY 487 picoammeter is an advanced electronic test equipment used for precise current measurements in the nanoamp range. In addition to being able to accurately measure small currents, 487 also allows users to measure voltage and resistance. KEITHLEY 487 is designed for use in electrical engineering, laboratory, and automated test system applications. 487 has a user-friendly interface, including a large high-resolution LCD display, menu-driven programming, and easy-to-understand indicators. Utilizing a 10-turn voltage decade knob, and a 10-turn current decade knob, the instrument can be programmed for precise voltage, current and resistance measurements. The instrument utilizes an advanced design for a fast measurement response time. KEITHLEY 487 features low thermoelectric noise, low input bias and offset currents, and high input impedance for improved stability and noise rejection. Designed with both auto-ranging and manual-ranging modes, it can measure loads up to 1,500 nA (nano amps). The instrument can measure direct current or alternating current. In addition, it features selectable ac/dc coupling which allows the user to select between either ac or dc measurements. 487 has built-in protection features including over-voltage, over-current, and under-voltage protection. An overload LED to warn the user if the load is exceeded. The instrument is equipped with a GPIB port for remote operation and programming. KEITHLEY 487 also is equipped with a rear-panel BUSY contact output for automated testing. This allows external devices to be synchronized in time with 487's measurement cycles. KEITHLEY 487 is compatible with SCPI-based programming languages, such as C, Visual Basic, and Visual C++. It also supports KEITHLEY graphical interface software, KEITHLEY Control Software Light. 487 has also passed extensive safety tests and comes with Environmental compliance certifications from CE, CSA, UL, and VDE. The instrument is designed to be used in a variety of industrial and laboratory settings, able to withstand shocks, bumps, and extreme environmental conditions. In conclusion, KEITHLEY 487 is a versatile and advanced picoammeter with the necessary protection features, fast measurement response time, and easy operation and programming with the additional capability to make precise measurements in the nanoamp range.
