H10 Sensors and D12 or F12 Transmitters
As a convenience, D12 and F12 gas transmitters save the sensor “Range”, “Blanking”,
“Averaging”, alarm level, and type settings, and restore them when the same or a similar
type sensor (same part number) is installed. This may lead to confusion if these values are
first set by the D16 and the sensor is installed into a D12 or F12 gas transmitter. The
transmitter will change these settings if they differ from the saved settings.
System
System “About” Page
When the D16 starts it displays the “About” page, which is shown below
in Figure 21. This page lists the revision level of the LCD, and the CPU
revision and serial number. The page also appears by touching the “About”
button on the “System Menu” page (see Configuring System Settings below).

Date and Time
The D16 contains a clock calendar chip that is accurate to within
approximately 1 minute per year. The clock is set at the factory and
maintained by a dedicated battery so that it is unaffected by removing the
primary battery. The date and time appear on the “Main Display”, and in data
log files, and should be set to local time prior to using the data logger.
Changing the date or time will not affect timestamps of data already logged.
The date format may also be set to either “mm/dd/yyyy”, or “dd/mm/yyyy”.
Changing it will affect dates on the display, and in new log files. However,
there is no effect on existing files.
Auto-shutdown
The D16 features a timer that will turn power off automatically when the
display is not touched for a period of time. This is designed to conserve
battery life when the “Wakeup” button is pressed accidentally. The feature is
disabled by default and must be enabled by the user, during which, the time
period may be specified. The D16 will not automatically shut down until the
“Main Display or “Trouble” page is displayed, and no gas alarms are active.
