The Line Frequency and Voltage Monitor simply plugs into any 120 VAC outlet for immediate use.
The Line Frequency and Voltage Monitor simply plugs into any 120 VAC outlet for immediate use. With no connecting probes or cables, it measures AC power-line frequencies to 550Hz with an accuracy three hundred times better than public utility tolerance. The Line Monitor can handle input frequencies from 45 to 550 Hz, sine or square wave. This rugged, compact unit features miniaturized and quartz-controlled circuitry.
Features
  • Verify accuracy and stability of synchronous motors and clocks
  • Check output of frequency-regulated and unregulated DC-to AC inverters
  • Monitor frequency of mobile and portable generators under load
  • Obtain direct reading of long-term average frequency of fluctuating power sources
