Programming the Basic Meter
Programming the basic meter consists of selecting the type of T/C or
RTD and selecting the temperature scale
° F or ° C.
The Digital Temperature Meter must be programmed for the type of
thermocouple or RTD it is to accept. Selecting the wrong type will cause an
incorrect temperature to be displayed.
Connect the thermocouple or RTD to J1 on the Main PCB.
Using the
TYPE
menu, enter a number from 0 to 10, this number defines the type
of thermocouple or RTD input required and the display resolution. The following
table is used to define the types:
