DAQFlex Message-based Firmware Specification Analog input calibration messages
14
REF
 Set the calibration reference voltage.
Message
"AICAL:REF=value"
Response "AICAL:REF"
value The voltage value.
Example "AICAL:REF=+1.250034V"
Note The voltage value is stored in EEPROM.
REFVAL
 Get the actual measured value of the currently set calibration reference voltage.
Message
"?AICAL:REFVAL"
Response "AICAL:REFVAL=value"
value The measured voltage value.
Note The voltage value is retrieved from the value stored in EEPROM.
 Get the actual measured hex value of the currently set calibration reference voltage.
Message
"?AICAL:REFVAL/HEX"
Response "AICAL:REFVAL=0xhex value"
hex value The measured voltage hex value.
Note Omitting "/HEX" from the query results in a loss of precision in the value returned.
RES
 Get the A/D resolution.
Message
"?AICAL:RES"
Response "AICAL:RES=value"
value The A/D resolution.
SLOPE
 Set the slope for the current AICAL:RANGE setting.
Message
"AICAL{ch}:SLOPE=value"
Response "AICAL{ch}:SLOPE"
ch The channel number.
value The calibration slope.
Example "AICAL{0}:SLOPE=–0.0025"
