Regarding accuracy, thermocouple accuracy is defined but ref. junction compensation accuracy is specified as well, do i have to sum the values to get the final accuracy of the system or... Best regards

does this come with the ac power adapter? does this come with the software to read on the pc?

Asked by: EHof
Hi EHof Thank you for the inquiry. AC adapter is sold separately. Software is good for up to Windows 7 32 bit only. This will not be updated. For newer logger please consider the RDXL6SD-USB. Best regards OMEGA

Hi does this have an input voltage of 0-170VDC?

Asked by: geogeo
The AC adaptor can be plugged into a 100 to 240 VAC supply to provide the meter with the DC Voltage provided by 4 AA batteries.
