The importance of the
code You may enter the menu only when you type in your code.
The code consists of 4 numbers. This prevents
unauthorised access.
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 .
Type in the code
1. Press the MENU button. The blinking

mnemonic

user code or the supervisor code.

MENU button. If a correct code has been type
in, the

(login as a user) or

(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 typed in, the mnemonic

( BAD C ode) is shown on the display and stays
there for 2.5 seconds; then the instrument exits from the
menu, and goes on with the measurement.
Start typing the code in again from Point 1.
Automatic exit from
the request for the code If no buttons are pressed, the instrument displays the
mnemonic

( T ime Out ) after 4 minute has passed
from the last pressing of a button, and it RESTARTS, i. e.
goes back to the clock mode. This solution is due to
security: should the instrument be left alone for some
reason, unauthorised persons will not be able to change
the settings of the instrument after 4 minute.
