Connect Temperature probe, turn on device via key.
After segment test the device displays some configuration:
• If the logger function is not off the time of the integrated clock will shortly be displayed.
• If a zero point adjustment was carried out the display shows shortly „nuLL Corr“.
After changing the battery the clock-setting menu is activated automatically (‚CLOC‘). Check the clock
