password system (a key sequence or a value), according to figure 9.
Fig. 9 - Password through key sequence or value
In case of a key sequence password, the user should press the UP, DOWN
and ENTER keys (exactly in this order) to access the configuration levels.
For a value password, the user must press the ENTER key for a second time
in order to view the number 0000 with the right end digit blinking. The position which
is blinking indicates the digit in the number to be changed by the user with the UP
and DOWN keys. Move to the digits on the left by pressing ENTER. After entering all
digits, press ENTER again. If the password is correct level 1 is accessed; otherwise,
it returns to normal operation (see figure 9).
The user can choose also both password systems, key and value. In this case,
if the user provides an incorrect sequence of keys, the display goes immediately to
the value password system.
The password number may be chosen by the user (personal) or it could be
used the number 2015. Note that the number 2015 is always accepted by the value
password system, which helps the user in case he forgets his password. In order to
enter a number for password or for any other parameter use the Indicator front panel
keys with the following functions:
UP
DOWN
ENTER
All configuration parameters are stored in the non-volatile memory and
determine the normal operation of the instrument. With these parameters the user
can adjust the instrument to his needs, when it is necessary to change the
configuration from factory.
Configuration parameters are distributed in six hierarchical levels shown in
figure 10.
