Note 1) During standby and during a single screen display, the unit outputs the value that is in memory. Note 2) During standby and immediately after POWER ON, the correct value is not output.

In this case, please obtain the information after waiting a short period of time after POWER ON. These types of information are output as reference information (these are not guaranteed information). Normally refer to temperature information 3.
