5.6Temperature

5.6.1The temperature of the process can be read at any time by entering the menu and calling for TEMPERATURE. Either °C or °F will be indicated depending on the position of DIP switch No. 1. Bank S1. See Section 4.8.

5.6.2The 0-5 Vdc and 0-1 mA analog outputs can be dedicated to follow the process temperature by simply placing DIP switch No. 8 in the off position. The temperature span of the output is set to the utility menu. See Section 4.8 and 7.4.

5.7Status

5.7.1The DOCN600 continuously checks the integrity of all stored data and monitors the condition of the measuring system. If a fault is detected, the FAIL LED above the display will turn red. The STATUS in the operation menu will provide a numerical code, giving a possible cause and a suggested remedy.
