The Keithley 2100/120 is a 6½-digit USB digital multimeter engineered for high-precision benchtop and automated test system measurements. It delivers 11 primary measurement functions with 8 math capabilities—including RATIO, percentage, Min/Max, NULL, Limits, mX+b, dB, and dBm analysis—supporting diverse electrical characterization workflows. The instrument achieves 0.0038% basic DC voltage accuracy on the 10 V range and 0.013% basic resistance accuracy on the 10 kΩ range, with fully specified accuracies across all functions for ISO-compliant documentation.
