  • Reliably handle a wide range of high-current applications with 2000 A AC + DC True RMS, 1400 A AC, and 2000 A DC
  • The large 58 mm (2.3 in) jaw capacity is suitable for large or multiple conductors
  • CAT IV 600 V, CAT III 1000 V rating for added user protection
  • In-rush current measurement captures ‘power-on’ surge current with accuracy and repeatability
  • High voltage measurement of 1000 V AC + DC True RMS, 600 V AC, and 1000 V DC allows the user to perform multiple tests with only one tool
  • Resistance to 400K ohms coupled with a continuity beeper provide the convenience of a multimeter in a clamp meter.
  • Accurately measure frequency up to 1 kHz for optimum troubleshooting
  • Quickly analyze readings using the MIN, MAX, and AVG functions
  • A large backlit display allows for easy visibility in low-lit areas
  • Use the display hold feature to capture readings even when the display cannot be viewed
  • Use the low-pass filter to smooth out noisy loads and stabilize readings


  • 20 mA dc current source/measure/simulate
  • Simultaneous mA and % of scale readout
  • DMM designed to meet 1000 volt IEC 61010 CAT III and 600 V CAT IV standards
  • Fluke Connect® compatibility for wireless data logging (with IR3000FC module*)
  • Precision 1000 V, 440 mA true-rms digital multimeter
  • Frequency measurement to 20 kHz
  • Min/Max/Average/Hold/Relative modes
  • Diode test and continuity beeper
  • Manual step (100%, 25%, Coarse, Fine) plus Auto Step and Auto Ramp
  • Externally accessible battery for easy battery changes


  • Be safer: Measure voltage to 1000 V ac through the open fork, without test leads.
  • Be faster: No need to open covers or remove wire nuts.
  • Be more efficient: Simultaneously measure voltage and current.
  • Be everywhere: 17.8 mm open fork is widest in the industry; measure up to 200 A on 4/0 wires (120 mm2).
  • Go beyond simple detection. Actually measure ac voltage and current values without test leads.


  • Three-phase power quality recorder with an Android tablet wireless front panel interface
  • Complies with IEC 61000-4-30 Class-A standards for correct evaluation of all measured values
  • Supports quick and reliable configuration even in awkward test locations with the wireless interface that provides a window into what the instrument is recording
