Sensor
As described in the Introduction, the D16 quickly adapts to measure
different gasses by inserting an appropriate H10 gas sensor module. The
module retains all of the calibration and configuration settings for the target
gas, such as the chemical name, units of measure, full scale “range”,
“blanking”, “averaging”, and the gas level alarm settings. The H10 module
also stores a history of the last 63 zero and span calibrations, which the D16
presents on the display.
When an H10 sensor is installed, the D16 presents a “Sensor
Information” page, as shown in Figure 19 below. This occurs at startup, and
when a sensor is installed, and also on timeout from the “Main Menu”. The
page also appears by touching the “Info” button on the “Sensor Menu” page.
The D16 will display a trouble alarm whenever the sensor is removed, and
will
automatically turn power off after 5 minutes
. See Trouble Messages on
page 57.

Gas readings are affected by three configuration settings stored in the
H10 sensor memory: “Range”, “Blanking”, and “Averaging”, which are
described below. Details on changing these settings follow in Configuring
the Sensor on page 35. Settings for the gas level alarms are covered in
Alarms on page 24.
