The Keithley 2420 High Current SourceMeter is a 60W instrument designed to source and measure voltage from ± 1 uV to ±60V and current from ±100 pA to ±3A. Production test applications for the Model 2420 include resistors and resistor network devices that must be tested at higher current levels, thermistors, solar cells, batteries, and high current or medium power diodes, including switching and Schottky diodes. The Model 2420 is also suitable for I DDQ testing of CMOS integrated circuits and monitoring the current consumption of battery-powered medical devices such as pacemakers. SourceMeter units can make standard 4-wire, split Kelvin, and 6-wire guarded ohms measurements, and can be configured for either the constant current or constant voltage method. 0.012% basic accuracy with 5 1/2 digit resolution.
