Fluke Digital Multimeter.

Operation

Both graded and ungraded sensors are used on SR-2 applications. Graded sensors are used to sense return air

and discharge air temperature. Ungraded sensors are used to sense coil and ambient air temperature. Both

graded and ungraded sensors are checked in the same manner.

Dual Sensors

Dual temperature sensors are provided for both return air temperature and discharge air temperature. The

sensors are located next to each other to insure common readings. One sensor is the control sensor and the

other sensor is the display sensor. The return and discharge control sensors are used for unit control. The return

and discharge display sensors are used by the HMI control panel to display the temperature.
