    These test and measurement circuits are not rated for measurements performed on circuits directly connected to the electrical distribution system referred to as MAINS.

    MAINS is a hazardous live electrical supply system to which equipment is designed to be connected to for the purpose of powering equipment. This product is rated for measurements of voltages from specially protected secondary circuits. Such voltage measurements include signal levels, special equipment, limited-energy parts of equipment, circuits powered by regulated low-voltage sources, and electronics.

    spd-note-warnings
    Warning  

    Do not connect the FD-11614 to signals or use for measurements within Measurement Categories II, III, or IV, or for measurements on MAINs circuits or on circuits derived from Overvoltage Category II, III, or IV which may have transient overvoltages above what the product can withstand. The product must not be connected to circuits that have a maximum voltage above the continuous working voltage, relative to earth or to other channels, or this could damage and defeat the insulation. The product can only withstand transients up to the transient overvoltage rating without breakdown or damage to the insulation. An analysis of the working voltages, loop impedances, temporary overvoltages, and transient overvoltages in the system must be conducted prior to making measurements.

    • 1 Base clocks can be synchronized with other FieldDAQ devices using the network synchronization feature.
    • 2 Measurement sensitivity is a function of noise and represents the smallest change in temperature that a sensor can detect. The values assume the maximum of the full measurement range of the standard thermocouple sensor according to NIST Monograph 175.
    • 3 I/O synchronization is system-dependent. Assumes the devices are connected in a line topology. For information about network synchronization accuracy, visit ni.com/info and enter Info Code syncacc.
    • 4 I/O synchronization is system-dependent. Assumes a system containing one hop. For information about achieving high accuracy synchronization, visit ni.com/info and enter Info Code fdsync.
    • 5 This allows for line topologies or network redundancy.
    • 6 With default software configuration. For information about creating reliable Ethernet-based systems, visit ni.com/info and enter Info Code fdenet.
    • 7 The total amount of power drawn by the device from the power input connector, including power delivered to external sensors.
    • 8 Working voltage rating is the highest RMS value of the AC or DC voltage across the insulation that can continuously occur when the equipment is supplied at rated voltage.
    • 9 Withstand rating is the highest RMS value of the AC or DC voltage the insulation can withstand without flashover or breakdown for a specified time.
    • 10 Temporary Overvoltage rating is the overvoltage of relatively long duration.
