SF 6 Portable MonitorInstruction 3015-5150 213.13.3 First Diagnostic ScreenIn the First Diagnostic screen, the user can toggle between displaying Bench Voltage / DetectorTemperature, and Noise / Box Temperature by pressing the Keypad Right button.Bench Voltage – This is the current peak-to-peak output of the IR detector. In the absence of gas thisvalue can range from 3.90000V to 4.50000V.Noise –The Noise value is a 16 point running average of the noise portion of the IR detector’s output. Thisreading is valuable mainly when gas is NOT present.Detector Temperature – This is the current detector temperature in °C.Box Temperature – This is the current internal enclosure temperature in °C.Fault Code – Current fault code. A value of <0000> indicates that no faults are being detected.Pressure Reading – This is the pressure as measured every purge cycle with the sample pump off andthe gas-sample inlet open. Its value is weather and altitude dependent and can range from 10.0 to15.5 PSIA.Purge Valve Asterisk (∗) – The purge valve can be opened and closed by pressing the Keypad Leftbutton. An asterisk appears on the display when the purge valve is open causing the monitor to draw airfrom its purge-air port.3.13.4 Second Diagnostic ScreenPPM Level – Parts Per Million Level is the current detected gas level, and is the volume concentrationreferenced to standard temperature and pressure.Average Absorption Unit – This is the optical absorbency. In the absence of gas the absorbency is0.00000 au. When sampling gas, its value varies proportionally with the gas concentration.μMoles/Liter – This is the absolute concentration in micro-moles per liter of gas.Detector Voltage – This is a running average of the IR detector’s bench voltage.Purge Valve Asterisk (∗) – The purge valve can be opened and closed by pressing the Keypad Leftbutton. An asterisk appears on the display when the purge valve is open causing the monitor to draw airfrom its purge-air port.0.1ppm 0.010.00004au 4.210vPPM Level μMole/LiterAvg.
