Figure 53: Password entry
As soon as the user wants to access a password-protected menu
or a password-protected value change, password entry is
prompted.
For this purpose, as shown on the LCD display, the digits 1, 2 and
3 are assigned to three buttons ,  and .
Example
If the password set is '1213', the user needs to push the buttons
, ,  and  one after the other. Each push of a button is
acknowledged by displaying the '*' symbol.
The password entered remains active until the user returns to
measuring mode or until the gas analyzer automatically switches
to measuring mode through the time-out function.
Time out function
If the user does not press a button for more than 5 minutes
while selecting menu items, the gas analyzer automatically
switches back to measurement mode (see LCD display in
measurement mode on page 107).
The time-out function is disabled as soon as the user changes
the value of a parameter or starts a calibration.
