5.14 Temperature
5.14.1 If your probe is a standard probe it will not be fitted with a temperature sensor and
therefore the 2200R will not monitor temperature. The TEMPERATURE item in the
menu will be skipped.
3.5.1 However if your probe has been ordered with an integral temperature sensor the
temperature of the process can be read at any time by entering the menu and
scrooling to TEMPERATURE. Either
°C or °F will be indicated depending on the
position of the dip switch.
3.5.2
The 0-5Vdc and 0-1mA analog outputs can be dedicated to follow the process
temperature by simply placing dip switch No.8 on S1 in the OFF position. The
temperature span of the output is set in the Utility Menu. Refer to Section 7.5
