After a password is assigned, the operator must log out to activate
it. Until then, anyone can continue to operate the instrument
without entering the new password.
Only one password can be defined. Before a unique password is
assigned, the system assigns
TETAI by default. This allows
access to anyone. After a unique password is assigned, to defeat
the security, the password must be changed back to
TETAI.
• Logout: Logging out prevents an unauthorized tampering with
analyzer settings.
• More: Select and enter More to get a new screen with additional

• Self–Test: The instrument performs a self-diagnostic test to
check the integrity of the power supply, output boards and
amplifiers.

instrument.
4.3.1 Setting the Display
NOTE: Contrast function is disabled.
If you cannot read anything on the display after first powering up:
1. Observe LED readout.
a. The LED meter should read all eights and periods.
b. If LED meter displays anything else, go to step 2.
2. Press Standby button twice to turn Analyzer OFF and ON
again. LED meter should now read all eights and periods.
4.3.2 Setting up an Auto-Cal
When proper automatic valving is connected (see Part II Chapter 3,
installation), the Analyzer can cycle itself through a sequence of steps that
automatically zero and span the instrument.
NOTE: If you require highly accurate Auto-Cal timing, use external Auto-
Cal control where possible. The internal clock in the Model
3010MA is accurate to 2-3%. Accordingly, internally scheduled
calibrations can vary 2-3% per day.
