The Fluke 8120A is a precision digital multimeter engineered for field and laboratory electrical measurements. It delivers accurate DC and AC voltage, current, and resistance readings across wide ranges with a 4.5-digit LED display and high input impedance. The instrument supports multiple power configurations and includes optional RF and high-voltage measurement capabilities.
Technical Specifications
Measurement functions include DC/AC voltage, DC/AC current, resistance, continuity, and conductance. The 4.5-digit LED display provides clear real-time readings. Input impedance is fixed at 10 MΩ.
Accuracy specifications are DC voltage ±(0.1% + 1 count) and AC voltage ±(0.2% + 5 counts). Operating temperature ranges from 0°C to 50°C; storage temperature from -20°C to 60°C.
Measurement ranges span:
• DC voltage: 0.1 mV to 1000 V
• AC voltage: 0.1 mV to 750 V
• DC current: 1 µA to 2000 mA
• AC current: 1 µA to 2000 mA
• Resistance: 0.1 Ω to 20 MΩ
• Conductance: 0.1 nS to 200 nS and 0.001 mS to 2 mS
Continuity detection provides immediate audible indication.
– Key Features
The 8120A operates from 100, 115, or 230 V AC line power at 50 to 500 Hz, with optional battery power. Dimensions are 9.2 in × 3.7 in × 10.7 in and weight is 5.7 lbs. Optional printer output is available for automated logging.
Accessory support includes RF probe for AC voltage measurement to 500 MHz, DC voltage probes rated to 5 kV and 15 kV, and rack mounting kits for single or dual-unit configurations.
– Typical Applications
The instrument suits field service work, bench laboratory testing, systems integration, and automated measurement scenarios where multifunction capability and extended voltage/current ranges are required.
