PASSWORDS

The H201Ti's user interface is protected by passwords. Entering a password is necessary
to modify parameters or to access specific sections of menus:
• Password No. 1 (first level): This password is 1253. It allows the user to modify almost
all the H201Ti's parameters.
• Password No. 2 (second level): This password is 1231. It allows the user to access the
following items:
– The Calibration submenu (to calibrate the H201Ti)
– The NewSensor submenu (to enter the parameters of the Hydran 201 sensor)
– The three Clear commands in the History submenu (to erase the historic data files)
Password protection prevents accidental or unauthorized changes of the H201Ti's
parameters. The passwords should be divulged to authorized personnel only, particularly
password No. 2. The passwords are common to all H201Ti's and cannot be changed.
Note: Passwords used in the Hydran Host software are independent from those entered via
the H201Ti's keypad, and they can be changed (see the Hydran Host Software Manual).
When the H201Ti requests a password, one of the following two messages is displayed:
• Password 1?
:1247
• Password 2?
:1247
Use the UP or DOWN key (see Figure 4-2 on page 4-8) to increment or decrement the
displayed value, and press ENTER to accept the value. The user is now authorized to
change the parameters until he quits the Menu Navigation mode. No password will be
requested again unless a higher level password is required.
Note: All modifications are recorded in the historic data file Events (see Section 4.5.1 on
page 4-12).
