"No Leaks Detected" - This indicator is the result of the sample and bypass manifold leak test
performed by MultiGard 5000 unit upon power up and every 8 hours thereafter. This test can also
be manually triggered on the Diagnostics screen. If the system leaks this indicator will change to
red and display "Leaks Detected".

push button on the Diagnostics screen. When disabled, the indicator will turn red and display
"Sensor Alarming Disabled".
“Alarming Disabled A.S. Upper Range Out Of Tolerance” – This indicator will appear when an
auto standardization was completed and any sensor’s upper range is out of tolerance. All alarming

combination as follows: When disabled the message "Analyzers Ready Disabled" is present
