Additional Features:

• Multifunction vacuum fluorescent dual display allowing the user to measure two different parameters of the same signal from one test connection, and view both measurements at the same time.
• True-RMS voltage and current, including AC + DC
• RS-232 interface standard, IEEE-488.2 option
• Frequency measurement to 1 MHz
• dB measurements: 21 selectable reference impedances. From 2 to 8000, and audio power from 2W to 16W
• Compare (Hi/Lo/Pass) function for quick in-tolerance tests
• 0.05% DC current accuracy for 4-20 mA current loop service
• Closed-Case Calibration: Calibration can be performed via the RS-232 (or optional IEE-488.2) interface or manually from the front panel. No internal adjustments are required
