Setup Enabled Features
The DFM may have one or more optional features enabled. These features are only enabled at the

Set button once brightens the LEDs.

the Y to an N.
The time setting screen displays hhh:mm (hours: minutes). Any time
value can be set from 0:01 to 168:00 hr:min.

Set the
minutes
value first. Press the UNITS button to increase the
minutes value or the RESET button to decrease the minutes value.

Y or N appears on the display. You have the option to temporarily
disable this feature by pressing the UNITS or RESET button to change
the Y to an N.
Any volume value can be set from 0.01E00 to 9.99E99
Note:
The “V” in the “OFFV” is actually a “U.” This is because of the
segments of the LED display.
NOTE:
The automatic shut-off on volume feature generally is not
enabled if the automatic shut-off on time has been enabled. However, it
is physically possible to have both enabled. The shut-off feature that is
most restrictive will occur first and thus terminate the sampling event.
