The 

SELECT SENSOR

 is the first function in the sequence. Virtually any thermocouple, RTD or

millivolt input can be selected. The display will read as follows to indicate this position on the
menu:

If the sensor is set correctly, press 

NEXT

 and skip to Section 4.4 of this manual; otherwise press

Enter. After pressing the 

ENTER

 key, the display will change to:

Indicating that the transmitter is set to a Type J thermocouple input. If this is the desired sensor, then
press 

ENTER

, otherwise press 

NEXT

 repeatedly to sequence through the available sensors. Each

time 

NEXT

 is pressed, the next available sensor selection is displayed.

Press the 

NEXT

 key to go the next sensor.

Press the 

NEXT

 key to continue through the different sensor selections.

NOTE:

The T/C SPEC or Special Thermocouple input is reserved for a special thermocouple input,
