PanelTemp (Panel Temperature)

The PanelTemp instruction is used to read the temperature of the datalogger wiring panel and output the value in degrees Celsius.

Syntax

PanelTemp ( Dest, f_N1 )

Remarks

The measurement from the PanelTemp instruction can be used as the reference temperature for thermocouple measurements.

Parameters

Dest (Destination)

The Variable in which to store the results of the instruction. Right-click the parameter to display a list of defined variables.

If this instruction has a Repetitions parameter and it is greater than 1, the results are stored in an array with the variable name. The array must be dimensioned large enough to hold all of the values returned from all of the Reps.

Type: Variable or Array

f_N1

Determines the lowest frequency that will be eliminated or notched out by the sinc filter. This filter notches out frequencies at integer multiples of f_N1 by averaging for a time equal to 1/f_N1; thus, lower f_N1 frequencies result in longer measurement times. Set f_N1 to the lowest frequency that should be filtered out. For example, setting f_N1 to 60 filters all multiples of 60 and above (60, 120, 180, etc.) but will not effectively filter lower frequencies; for example 30 Hz. Any value between 5 Hz and 93.75 kHz can be entered, but common options for filtering noise are:

Option	Description
15000	Performs a 0.0667 millisecond integration (for fast measurements)
60 (or _60Hz)	Performs a 16.67 millisecond integration (filters 60 Hz noise)
50 (or _50Hz)	Performs a 20 millisecond integration (filters 50 Hz noise)

Type: Constant
