RES

Get the resolution of the A/D converter.
Message

"?AI:RES"

Response "AI:RES=value"

value

The ADC resolution, for example S24.

Note

The first character indicates if the value is signed (S) or unsigned (U). The second value

indicates the resolution in bits.

SCALE

Enable or disable scaling of A/D channels.
Message

"AI:SCALE=value"

Response "AI:SCALE"

value

ENABLE, DISABLE

Example

"AI:SCALE=

Note

When SCALE is enabled, the device returns values that are converted to an appropriate

unit based on the CHMODE property. For example, when CHMODE is set to DIFF, values

are returned as voltage. When CHMODE is set to TC/OTD, values are returned as
temperature. When SCALE is disabled, values are returned as counts.

This message is processed by the DAQFlex Software library, and is not sent to the
