MicroBio Operating Manual [P0001W006]
When sampling is complete, the display will show the message
SAMPLING
DONE and the final
volume taken. The red LED will flash and a warning tone will be made. To acknowledge the sample,
press START.
The display will revert back to Take Sample mode.
Delayed Start
The user may wish to undertake sampling remotely.
On some occasions, remote operation of the MB2 is required, such as in sealed clean areas. To
avoid problems associated with infra red remote controls, i.e. the operator and sampler may not be
in line of sight and windows may not be present, or with wireless types where steel walls may block
transmission, the MB2 employs a time delay start for remote operation.
This allows the operator to set a time between 10 seconds and 3 hours, in variable increments,
before sampling of a user defined volume commences.
When this menu option has been selected, use
+
and
-
to change the time delay and press
START
when ready. The user can then select the volume required in the same way as in the Take Sample
mode described earlier.
When the sample is started, the delay countdown will begin and the LED will flash slowly, a beep will
sound every second and the display will indicate in how many seconds sampling will start. Once
sampling has started,
MENU
can be pressed as normal to cancel.
At any time in setting a delay, press
MENU
to exit. Pressing
+
and
-
together when setting the delay
will set the factory default delay of 60 seconds. The MB2 will remember the last used preset delay
for next time, even if the unit has been switched off.
User Presets
Some users find that for almost all the sampling they undertake the volume of air sampled is always
the same. At this menu item, the user can set six possible Preset Volumes which are stored even if
the MicroBio is switched off and on.
When this menu item is first selected, the user is presented with
Preset Volume
[1] and the current
set volume. This value can be adjusted using the
+
and
-
buttons. When the desired volume is
reached, press the
START
button to store the value.
The display then moves onto the second preset volume. If a particular preset is not to be altered,
skip past by pressing START until the required preset is reached. When all preset values have been
set and stored, leave this menu option by pressing MENU.
Unit Status
When Unit Status mode is selected, use the
+
and
-
keys to navigate between the various screens.
Pressing
START
or
MENU
will take you back to the main menu list.
Battery Level
This display gives a percentage indication of battery capacity.
It is only an approximation and
cannot be used to determine the exact operating hours of volume taking capacity remaining in the
battery.
