For example, I did not even manage to make a Main reset to time delete all the old data. When I press the indicated key in the user guide, anything happens, but I'm not getting the supposedly existing opportunity to reset offered. (Addendum: In the instructions at a location, you should press the OK button Elsewhere it is against the SET button for the same function, of course, only the SET button is right Who writes those instructions and why read not even.... someone correction?)
Synchronization is also called an anticonvulsant. One can not read the data from a remote device, as you only have to press a button on the device. The reading of the data is extremely tedious, 30 mins for 25,000 measured values. No idea why this is taking so long ...
The included software is a joke. Not even a graphical representation is possible.
I would part, given the limitations of the price do not buy it again.
