7051 Images

  • Universal calibration and system control
    Mounted centrally in the primary console the 7051 combines a precision multifunction calibrator, 6½ digit multimeter, and touch screen PC.
    It is the principle module for on-site facilities that require high performance calibration and maximum functionality.

    Calibrator (source)
    Provides a wide range of calibrated outputs for AC/DC voltage and current, RTD and thermocouple simulation, plus a range of resistance and frequency functions. Internal options can be added for increased capabilities. These include high voltage/current, capacitance/inductance, and oscilloscope calibration. Further enhancements can be made by additional side modules, adaptors, and benchtop instruments.

    Digital Multimeter (measure)
    The integral 6½ digit multimeter that can measure DC voltages to 1000V, AC voltages to 750V, resistance to 100MΩ, and frequency to 300kHz.

    PC Control Centre
    The 7051 control centre is a PC with a 64 bit quad core processor, running Windows 8.1, with a 10.4” capacitive touch screen display. An optional PC upgrade with 12.1” display is also available. The calibrator/multimeter control software allows the wide range of functions to be easily selected using mouse, keyboard, or touch screen. 

    EasyCal Software
    EasyCal calibration software is pre-loaded on the 7051 and enables automatic calibration to increase speed and efficiency of work. In addition EasyCal has features to manage and administrate both inventory and quality control. To complement the system a printer and connectivity kit is supplied as standard, for generation of certificates and reports.

    Using EasyCal the operator can read back from compatible electrical, temperature, pressure, and loop modules within the bench. Furthermore the software can be used with external instruments such as dry block calibrators and portable test instruments. 

    The 7051 Plus Package
    A comprehensive package including specific options to cover the calibration requirements for electrical and process applications. As a package it incorporates the full internal capabilities of the 7051, and is complemented by external adaptors for increased functionality. It is suitable for users in need of rapid multi product testing with automated test runs using EasyCal software. Further supplied accessories include a bar code reader for quick identification of devices in EasyCal, and label printer for creating ‘Calibrated’ labels to be placed on instruments.
