Die Stoffausscheidung Der Höheren Pflanzene instrument. It therefore becomes necessary to suitably reduce, or amplify, the magnitude of the measurand so that it has a value compatible with the measuring instrument to be used. In addition to these requirements, the effects of the instrument’s impedance must always be considered for this may effect the value indicated for the measurand.

Thus a system of comparisons must be established whereby any measurement made can be related to the standard value. Figure 7.1 gives a possible chain of relationships by which everyday measurements in electrical quantities may be evaluated in terms of the accepted standard values.

Die Stoffklassen der organischen Chemies a prestige exercise. This is of little value if within a week, justifiable pressure is brought to bear by one’s colleagues and the prestige instrumentation system is reduced to its minimum requirements — which could be two suspect multimeters and the oldest ‘scope in the department!

In addition to these features many digital instruments have an output facility enabling permanent records of measurements to be made automatically.

https://doi.org/10.1007/978-3-642-86369-1uation required attendants to take the measurements. This used to be done somewhat laboriously and at times with dubious accuracy. However, now, when some form of data recorder is used, readings may be made with known limits of error either as a continuous record or in a predetermined sequence at controlled time intervals over an extended period.
