Channel Settings

 

Change the acquisition method of each channel or reset engineering units.

 

 In the Edit menu, click on Channel Settings....

 

  Choose Edit Channel Settings... (ALT, E, G).

 

                                               OR

          Press F10.

 

This displays the Channel Settings Dialog Box

 

 

The Channel Settings Dialog box allows you to choose a gain setting, acquisition method, input type, set temperature units, and reset engineering units.

 

Select the connected Thermocouple when using Thermocouple Input Type. Uncheck the Fahrenheit checkbox to use Celcius.

Filter length values ("Filt Len") 1 through 64 affect the width of a moving window average for rate.

 

Acquisition Methods

Average

Default method. This method averages all of the data points in the burst sample and reports this average as the single value for storage and display.

 

Last Point

This method reports the last input data point in the burst sample for storage and display. The rest of the data points in the burst sample are ignored.

 

Maximum

This method reports the highest value data point in the burst sample for storage and display. The rest of the data points in the burst sample are ignored.

 

Minimum

This method reports the lowest value data point in the burst sample for storage and display. The rest of the data points in the burst sample are ignored.

 

RMS

Converts AC signals to DC data. The square root of the mean square value, computed over the number of samples specified in RMS Window Size, is acquired and displayed for the selected channel. Note: You should specify the number of samples before selecting this acquisition method. To designate the number of samples and for a more detailed explanation of the RMS acquisition method see RMS Window Size.Note: this method is not available for Thermocouple Input Types.

 

Frequency

This method is for use with frequency measurements - allowing a more accurate representation of a frequency waveform by acquiring and displaying a value proportional to the frequency of the input pulses. The highest frequency that can be converted is half the device burst rate divided by the number of channels. Note: The Frequency preferences should be set before selecting this method. See Frequency for complete details.Note: this method is not available for Thermocouple Input Types .
