- Page 27 3.7.2 Recommended wiring scheme It is recommended that the UNO thermometer is used in conjunction with the Land DIN Power supply Unit (DPU). In addition to providing the correct power supply voltage for the thermometer, the DPU has simple connections for mains supply, temperature output signal and Peak picker reset command signal.
- Page 28 'Reset control' The reset control must be electrically isolated from the indicator. When used with an UNO, only the connections shown in Fig. 16 must be made to the DPU. Do not make any other connections to the DPU.
