Page 10: Installation
Installation Lead Wire Identification The 5618B PRT is equipped with a four-wire cable (see Figure 1). Four lead wires are used to cancel lead wire resistance. For best results, the readout device should be equipped to handle four-terminal resistors. The lead wires are two different colors. Lead wire pairs attached to each end of the sensor are identified by red and white insulation. -
Page 11: Operation
Small Diameter Industrial RTD Operation Operation For best results, be familiar with the operation of the heat source and the readout instrument. Be sure to follow the manufacturer’s instructions for the readout instrument and the heat source. Immersion Requirements Stem effect can cause measurement errors for any thermometer. This error is due to heat lost or gained by the sensing element through the thermometer stem. -
