The device initialises after the supply voltage is connected. The device type and
software version appear in the display. After the device is finished initialising, it en-
ters the operating level and the current temperature and all safety-related settings
are displayed. The peak value buffer is displayed by briefly pressing the
button.
The configuration level is displayed by pressing and holding the
button for 2
seconds. All parameters determining the properties of the device are programmed
here. A password must be entered in order to enter the safety area of the configu-
ration level. If an incorrect password is entered, an error message appears in the
display. The device switches back to the operating level after this message or if no
password is entered. After an incorrect password has been entered three times, the
device enters a safety timeout for 60 minutes. The progress of this safety timeout is
shown in the display. The safety area is accessible with entry of the correct pass-
word. Settings can be made here, which must be protected from unauthorised
change. After the last menu item or if no button is pressed for more than 2 minutes,
the devices switches back to operating level automatically and the current meas-
urement is shown in the display. The configuration level can be exited at any times
by pressing the
