Just a heads up for everyone who uses the logging capability (btw, i use ultradmm.com):
I did long time logging of UT61E thru the original USB cable UT-D04 (purchased from official UNI-T distributor) because i had lost the original serial cable. My logged data ended corrupt because in the Excel file there were missing lines (data rows). If the Excel file has 216,000 rows, then this would equal a time period of 108,000 seconds or 1800min or 30hrs. Check the time stamp of the first row and compare it with the time stamp of the 216000th row. The difference in time should be exactly 30hrs.
This was not true with my brand new
UT-D04 data cable, which meant that the file was incomplete, which i was able to verify.
So i bought the original spare part, it is called
UT-D02 and can be referenced from here:
http://www.uni-trend.com/en/product/list_370_1.htmlWith this serial cable, i am getting the complete log, all 216000 rows for a time period of exactly 30hrs.
This may also be the explanation why UNI-TREND continues to package/ship the retail UT61E box with the serial cable and not the USB cable.
