7.2. Typing the code (password) in
The importance of the
code
You may enter the menu only after you have typed your code in. The
code is made from 4 numeric characters. This solution prevents
unauthorised persons from changing the settings of the instrument.
Levels of authorisation
User level:
allows the modification of the most necessary parameters
only. The rest of the menu is not even shown for users. The user code
default factory setting is:
0000.
Supervisor level:
allows the modification of all parameters for the
authorised person. The supervisor code default factory setting is:
1000.
Typing the code in
1. Press the
►
Menu
button. The blinking
mnemonic shows that
the device is asking for the code.
2. Four zeros appear:
. The zero at the left side is blinking.
3. Use the
▲
and the
►
buttons, type in either the user code or the
supervisor code.
4. Press the
◄
Esc
button. If a correct code has been type in, the
mnemonic
(login as a user) or the mnemonic
(login as a
supervisor) is displayed and stays there for 2.5 seconds; then the first
menu item is shown on the display:
.
5. If an incorrect code has been typing in, the mnemonic
(BAD
Code) is shown on the display and stays there for 2.5 seconds; then
the instrument exits from the menu.
Start typing the code in again from Point 1.
Automatic exit from
the menu
If no buttons are pressed, the instrument displays the mnemonic
(Auto Escape) after 5 minutes has passed from the last
pressing of a button, and goes back to the measuring mode. This
solution is due to security: unauthorised persons, after 5 minute, will
not be able to change the settings of the instrument, should it be left
alone for some reason.
