If someone posts a published test or instrument without the permission of the copyright holder, they may be violating copyright and could be legally liable.

If you plan to obtain an actual copy of the instrument to use in research, you need to be concerned not only with obtaining the instrument, but also obtaining permission to use the instrument. If you need information about a research instrument, what kind of information do you need? Do you need information on the structure of the instrument, its content, its development, its psychometric reliability or validity? What do you need? Note 4: ANSI/ISA-51.1-1979, revised 1993, pertains to dead band.Are you trying to find background information about a research instrument? Or are you trying to find and obtain an actual copy of the instrument? Note 3: The instrumentation industry expresses dead band as a percentage of span. Note 2: Dead band produces phase lag between input and output. Note 1: There are separate and distinct input-output relationships for increasing and decreasing signals. The Automation, Systems, and Instrumentation Dictionary adds these notes as further definition. 70 indicates 70 consistency in the scores that are produced by the instrument. Some researchers feel that it should be higher. For research purposes, a minimum reliability of. In process instrumentation, the dead band is the range through which an input signal may vary, upon reversal of direction, without initiating an observable change in output signal. Generally speaking, the longer a test is, the more reliable it tends to be (up to a point).
