One plug connects the four current probes. The instrument automatically detects, scales and powers the probes. These variable range current probes are easily set to 15 A, 150 A, or 3000 A for high accuracy in nearly any application.

Color screen will automatically provide confirmation that connections are accurate.  With one easy push of the record button, you are ready to go.

  • Able to verify electrical system capacity before adding loads
  • Identify harmonic issues that may cause damage or disrupt critical equipment
  • Track dips and swells that cause spurious resets or nuisance circuit breaker tripping
