In case of password by key, the user should press the UP, DOWN and ENTER
keys in sequence to enter the configuration levels.
In case of password by value the user should press the ENTER key a second
time to obtain the display of number 0000 with the last digit flashing on the right. The
flashing digit indicates the position where the digit of a 4-digit number will be entered by
the user. In order to move to the other digits to the left of the number one should press
the ENTER key. After entering all digits, press once more the ENTER key to switch to
level 1 in case the password is correct; otherwise, the system reverts to normal operation
mode (see figure 8).
The user may even select both password systems, by key and by value. In this
case, if upon receiving a request for a password the user enters a wrong key sequence
he will be immediately reverted to password by value.
The password may be a number selected by the user (customized), or the
number 2058 or 2059 according to the Station model. Note that in case of password by
value the number 2058 or 2059 (for each Station model) is always enabled, to help the
user in case one does not remember the password. In order to enter a password number
or any other parameter value, use the Station front keys which have the following
functions:
All configuration parameters are stored in the non-volatile memories (E2PROM
and NVRAM) and determine the instrument normal operation. Through configuration
parameters the user may adapt the instrument according to his requirements. Normally
the DCY-2058 and 2059 Stations are factory configured and the user is not expected to
enter the configuration mode. However, nothing prevents the user from reconfiguring the
instrument in case a new application so requires. This is made possible in view of the
