  • A unique earth ground tester that performs testing with and without stakes
  • Tests 3- and 4-pole fall-of-potential, and 4-pole soil resistivity (with stakes)
  • Performs selective earth ground rod testing (one clamp + stakes)
  • Performs stakeless earth ground rod testing (two clamps)
  • Features Automatic Frequency Control (AFC) to minimize the effect of interference


The 1586A Super-DAQ is the most accurate and flexible temperature data acquisition system on the market. It scans and records temperature, DC voltage, DC current, and resistance for up to 40 input channels and scan speeds as fast as 10 channels per second. The Super-DAQ can be configured for use as a multi-channel data logger in the factory or as a precision reference thermometer for benchtop sensor calibration in the lab.

  • Measure thermocouples, PRTs, thermistors, DC voltage, DC current, and resistance
  • Best-in-class temperature measurement accuracy
    • PRTs ±0.005 °C (using external DAQ-STAQ Multiplexer)
    • Thermocouples: ±0.5 °C (using High-Capacity Module and internal CJC)
    • Thermistors: ±0.002 °C
  • Input channels: Up to 40 isolated universal inputs
  • Flexible configuration: Internal High-Capacity Module and/or DAQ-STAQ Multiplexer
  • Selectable scan speed: Up to 10 channels per second
  • Four modes of operation: Scan, Monitor, Measure, Digital Multimeter (DMM)
  • Real-time color trending: Chart up to four channels simultaneously
  • 6 1/2 digit display resolution for DC voltage, DC current, and resistance
  • Current reversal minimizes thermoelectric effects, improving PRT/RTD measurment accuracy
  • Automated sensor calibration: Control Fluke Calibration temperature sources such as dry-wells or micro-baths for automated calibration routines
  • Data storage: Records up to 20 MB of data and setup files to internal non-volatile memory or to an external USB drive. Transfer data to a PC using the USB drive or LAN connection and view data in Microsoft® Excel
  • Data security: Administrator and user profiles for protecting settings and ensuring test traceability
  • Mx + B scaling and channel offset zero function
  • Alarms: Two independent, user-defined alarms for each channel indicate when an upper or lower range has been exceeded


  • Non-contact voltage detection
  • AutoVolt automatic AC/DC voltage selection
  • Prevent false readings caused by ghost voltage with selectable low-impedance mode
