⭕ This is a FLUKE 5500A Multi Product Calibrator with Option SC600 (600 MHz Oscilloscope Calibrator) and calibration performed by Fluke! The Fluke Z540 calibration includes full incoming and outgoing test data. The 5500A sources direct voltage and current, alternating voltage and current with multiple waveforms and harmonics, two simultaneous voltage outputs or voltage and current, and simulates power with phase control, resistance, capacitance, thermocouples and RTDs. The 5500As Oscilloscope Calibration options provide level sine wave, fast edge, time mark and amplitude signals for calibration of oscilloscopes up to 600 MHz. The 5500A calibrates electrical measurement devices including:

Handheld and bench multimeters
Oscilloscopes and ScopeMeter Test Tools
Wattmeters
Analog volt/ohm/amp/watt instruments
