The Agilent/Keysight 3468A Option 001 is a 5½ to 3½ digit digital multimeter delivering six measurement functions: DC voltage, true RMS AC voltage, 2-wire resistance, 4-wire resistance, DC current, and true RMS AC current. Display resolution is selectable across 5½, 4½, or 3½ digits, trading measurement speed against noise rejection as application demands.
Autoranging operates across all functions. The instrument features closed-box electronic calibration—eliminating internal adjustments and executable manually or remotely via the built-in HP-IL interface. Remote programmability provides control over functions, ranges, and measurement modifiers. Option 001 includes a rechargeable battery pack for field operation.
Technical Specifications
DC Voltage: 30 mV to 300 V with 1 µV sensitivity. Input resistance exceeds 10 GΩ on ranges to 3 V; 10 MΩ ±1% on 30 V and 300 V ranges. Maximum non-destructive input: 300 Vrms or 450 V peak. Accuracy specified as ±(0.0035% of reading + 2 counts) on the 3 V range over a 24-hour period.
