Thanks John, the provided example "DtAinContTEMP.vi" works fine. However, I cannot find this specific example within my LV-Link3 (3.10.2.0) installation. Is there an older version where I could find this example, and also other working ones if needed later on ? On the opposite, does LV-Link3 (3.10.2.0) and OpenLayers 7.8.9 still support the DT9806 USB daq ?

Hi John, Thanks for you reply. You are completely right, channel has to be set to 'Differential'. Unfortunately, this does not solve the issue. I still get the same error "Float data is not supported on this device". (see toto_error_differential.png). The provided example 'DtAinThermocoupleContinuous.vi' does not work, but with a different error "Invalid range". Nevertheless , our DT9806 seems to work fine, according to QuickDAQ software. Any advices ?

Hi I am trying to control a DataTranslation DT9806 USB Daq (actually, it's a Keithley KUSB-3108, but it is rebranding, AFAIK) using LabVIEW. The DT9806 seems to work fine, I can record measurements (voltage and thermocouple) using the QuickDAQ software. But with LabVIEW + LV-Link3 library, I cannot record thermocouple measurements: Using provided examples: "DtAinSingle.vi" works fine "DtAinThermocoupleContinuous.vi" returns "Error 29 : Invalid Range" Modifying "DtAinSingle.vi", only adding the "DtOLSetChanThermocoupleOptions.vi" subvi, it returns "1082 : Float data is not supported on this device". Am I missing something obvious ? Thanks is advance, regards. Nico
