DPM-RT-2 Operating Manual
The DPM-RT-2 also supports most time zones around the world, including automatically adjusting the time
for daylight savings. To select a new time zone, the user will tap on the
Time Zone Entry
Button and enter in
the time zone’s standard abbreviation. For example, the standard abbreviation for Australian Eastern
Standard Time is
AEST
and for
Australian Eastern Daylight Time
the abbreviation would be
AEDT
. The DPM-
RT-2 will then list all time zones matching the abbreviation for the user to select the appropriate one. If a
time zone that supports daylight savings time is selected, the time will automatically be shifted
forward/backward when required.
If the
Update Time from Internet
button is tapped, then the unit will fetch the time from the internet and
update the current time on this screen. Any changes will not get saved until the
Green Tick
is tapped, if the
Red Cross
is tapped instead all changes are discarded.

Diagnostics
The Diagnostics Screen gives the user a snapshot of
the current state of the unit.
In the
DPM Sensor
section, the
Current PM
and
Current ADC
values are shown to help identify any
sensor issues. The current sensor status is also
shown along with the calibration points including the
Zero ADC
,
Span ADC
and
Span PM
values. If the
sensor is at 40°C, then the
Sensor Heated
will show
Yes
otherwise
No
will be shown.
In the
System
section the
Battery Voltage
and
External Voltage
are shown as well as the
Charging Status
of
the internal NiMH battery. The
Fan Status
will show if the internal fan is running and the temperatures of
various parts of the DPM-RT-2 will be displayed. The battery temperature will only be displayed while the
unit is charging.
The charging states of the internal battery include:
•
N/A:
Unit is not charging due to external power being too low or not connected. External voltage
must be at least 9VDC to charge if the unit is powered off, and at least 12VDC to charge when the
unit is running and no more than 36VDC.
•
Charging:
Battery is currently fast charging.
•
Top Up:
Battery is currently trickle charging.
•
Charged:
Battery is fully charged.
•
Paused:
Battery charging is paused due to the external voltage being too low, less than 12V while
the unit is powered on.
•
Batt Temp:
Battery charging is paused due to the battery being too hot.
•
Fault:
A hard fault has occurred during charging; this can occur if the battery is extremely flat and it
takes longer than 4 hours to charge, removing external power and reconnecting will restart the
battery charging. If this occurs for any other reason, it indicates the battery has a fault.
The internal air pump can also be turned on and off via the
Pump On
and
Pump Off
buttons respectively.
This allows the user to view the diagnostic information while the unit is running.
