DrDAQ reading temperature in Celsius

Postby beacon » Fri Nov 19, 2004 10:48 am

I am developing a new application in VB.NET using DrDAQ.

Calling the function drdaq_get_value(channel) works ok for all channels except for reading the Temperature value (channel 6), which returns 0.

I can force a Farenheit reading by using the function drdaq_apply_fix but would prefer the value to be returned in Celsius.

Can anyone help please ?

When using the DrDaq what results do you get win Picoscope or Picolog for the temperature. The same functions are used in these application as our available in the dll's provided. Also mkae sure that the same driver is being used by both your application and Pico's applications.

Thank you for your post.

The DrDAQ temperature probes will not work below 200 degC. You would need to use a different logger and different sensors, for example a TC-08 and an appropriate thermocouple.

Hope this helps

Best Regards
