I have an application where I need to log multiple 50Hz AC voltages from AC current clamps. (More inputs than the CM3 can handle) I have the following questions regarding PicoLog software in connection with a Picolog 1012. If I select a very short sampling interval will I just log the instantaneous ...

Hi Hitesh,
Yes, that works. Updating the dll to 1.0.6.2 solves the PLCM3OpenUnit problem.
So for your reference, the SDK is shipping with an outdated 32 bit plcm3.dll
thank you again,

plcm3.dll (32bit) version 1.0.4.9
Thank you for your alternate suggestion. I am in fact already using PLCM3GetUnitInfo USB_version to check for the hardware presence as I have discovered that returns 0 correctly. I just thought PLCM3OpenUnit would be a logical place to check.

I am confused by the line g_status = PLCM3OpenUnit(&g_handle, NULL); My understanding is the function should only return 0 if it completes successfully. In fact it appears to return 0 even if the CM3 is no longe...

All compiling OK now, but now the code is working I have another question which I will post under a new thread 'g_status = PLCM3OpenUnit'

I am using your sample C console code using Code Blocks IDE and GCC compiler. the compiler complains that all the references to the PLCM3 functions are undefined, for example: undefined reference to `_imp__PLCM3...
