NOTE:If you log off the system using the LOGOUT function in the

system menu, you will now be required to re-enter the pass-

word to gain access to Alarm, and Range functions.

4.3.4 Logging Out

The LOGOUT function provides a convenient means of leaving the analyzer

in a password protected mode without having to shut the instrument off. By

entering LOGOUT, you effectively log off the instrument leaving the system

protected against use until the password is reentered. To log out, press the

System

button to enter the

System

function.

4.3.5 System Self-Diagnostic Test

The Model 2010B has a built-in self-diagnostic testing routine. Pre-pro-

grammed signals are sent through the power supply, output board, preamp

board and sensor circuit. The return signal is analyzed, and at the end of the test

the status of each function is displayed on the screen, either as OK or as a

number between 1 and 1024. (See System Self Diagnostic Test in chapter 5

for number code.) If any of the functions fails, the System Alarm is tripped.

Note: The sensor will always show failed unless identical gas is

present in both channels at the time of the SELF-TEST.

The self diagnostics are run automatically by the analyzer whenever the

instrument is turned on, but the test can also be run by the operator at will. To

initiate a self diagnostic test during operation:

Press the

System

button to start the

System

function.
