Working with the Diagnostic Screen

Overview

The Diagnostic Screen displays reference values for use by repair technicians for troubleshooting purposes.

Navigating to the Diagnostic Screen

Display the System Screen (Page 31); press the key adjacent to the target AGM300 unit to go to that monitor’s AGM Setup Screen #1 (Page 37); and then press the DIAG key to go to the selected monitor’s

Diagnostic Screen.

Diagnostic Screen Overview

The Diagnostic Screen contains sensor data and status information useful for troubleshooting various fault conditions. An explanation of each line is given below along with normal operating ranges.

LINE 1: Detector Voltage – This is the peak-to-peak output of the IR sensor, in the absence of ammonia gas this value can range from 3.900V to 4.500V.

LINE 2: Average Detector Voltage – This is simply a running average of the values displayed in line 1.

LINE 3: Zero Voltage – This is the IR sensor output that was stored during the last purge cycle and has the same range as line 1.

LINE 4: Noise – This is a 16 point running average of the noise portion of IR bench output. This reading is valuable mainly when ammonia gas is NOT present.

LINE 5: Average Absorbency – This is the optical absorbency computed from the values in lines 2 and 3. In the absence of ammonia gas the absorbency is 0.000AU. When sampling gas, its value varies proportionally with the gas concentration.

LINE 6: uMoles/L – This is the absolute concentration in micro-moles per liter of ammonia gas based on line 4 and the internal calibration. There are two figures given. The first (which is annotated by a B) is the actual measurement at the IR bench. The second is the calculated value corrected to ambient conditions (temperature + pressure).
