Although it could be used without any problem, the points to be noted are as follows. · When outputting, it is necessary to purchase the connection code separately. · Since there is no data output button on the main body, when transferring data to the personal computer, it is necessary to purchase a code with button separately, not a normal code. (It is a released item around January 2015, old catalog is not posted.) · When replacing the probe, it is very scary and it is scary but it was removed with pliers. Likewise, I used a pliers because the lifting lever attachment part could not come off only with a precision screwdriver. · Proofreading documents are not attached.
