<p>The current (I) for measurement passes through the resistance formed by the resistive layer (5) deposited on an insulating substrate (1). The latter resides between the injection terminals formed of high conductivity layers (2a,2b). The p.d. (V) developed across the measurement terminals (6,7) spaced along a layer (5) is a direct measure of the current (I). One or more calibrating cuts (12,13) are made down to the substrate in the layer (5) between the terminals (6,7) and from the edge of the layer. These cuts channel the current and are used to accurately set the ratio V:I.</p> |
