If the D16 and H10 sensor are functioning normally, the “Main Display”
is visible. Verify the pump is running and drawing air into the inlet port. If a
problem is detected, the pump motor remains off and a trouble alarm
appears (if this is the case, see Troubles and Exceptions on page 57).
Shutdown
To turn the D16 off, touch the “Off” button when it appears on the
display, or hold the “Wakeup” switch down for one second (see Figure 3,
page 9).

Gas Reading, Units, Name, and Temperature
The gas concentration reading appears at the center of the display in a
large, easy to read font, along with the chemical name, units of measure nits
of measure, and gas temperature. The gas name and units of measure are
fixed, based on the design of the sensor.
Settings in the sensor memory affect the behavior of the gas reading. In
particular, the sensor’s full scale range setting,
Range
, controls the maximum
displayed value and determines the resolution of the reading, as shown in
Table 1 (below). The gas reading will report up to 120% of the range setting,
and even higher for most sensors.
