1) Raw Sensor Readings
The raw sensor readings provide a quick diagnose on the
response and the sensitivity of each sensor. When zero gas
(fresh clean air) is applied to the monitor, the raw sensor
readings typically should be between 200 to 700 for toxic
and VOC sensors, between 100 to 1300 for LEL sensor and
between 1200 to 2300 for oxygen sensor. If the raw reading
is outside these ranges when zero gas is applied, the sensor
or the electronics may be defective.
When a specific gas is applied to the monitor, the
corresponding sensor should respond and the raw reading
should increase or decrease. If the reading of the
corresponding sensor does not change when the specific gas
is applied, then the sensor may be defective.

2) Sensor Name
All the toxic, oxygen and LEL sensors have a non-volatile
memory which contains the sensor identification and other
vital information, such as manufacturing date, expected
operating life, etc. If a sensor is programmed and installed
properly in the monitor, the sensor name should be
displayed. If the sensor name does not show up in the
display, then the sensor may not be programmed properly or
may be defective.
