12. OPERATING MODES
The D1
+
has 4 user-selectable operating modes for use in varying environments and
reporting requirements.
• Normal (default)
• In-cab
• Data log
• Live data
12.1 Power management
‘Normal’ mode captures and records data at the specified logging interval, allowing the D1
+
to provide real-time warnings and alarms on changing particulate levels.
‘Normal’ mode is intended for use when the D1
+
device is used to monitor individual
personal exposure to particulate levels within a working environment.
When configured to ‘Normal’ mode and connected via USB interfaces, the D1
+
will power
down its particulate sensor to allow for faster charging and data download.
This operating mode is indicated through the flashing of the battery indication symbol during
normal operation.
The use of the D1
+
in ‘Normal’ mode allows for both real-time alerting and on-device data
capture to take place simultaneously. The D1
+
is designed to allow warning alarms to be set
against a single Particulate Measurement (PM) value, however the device itself will log sensor
data for the following sizes for oine review.
• PM1.0
• PM2.5
• PM4.25
• PM10.0
When recording PM readings to the internal memory, the D1
+
will log the maximum value
for each size at the specified logging interval.
In ‘Normal’ mode, the user selected alarm PM size readings are taken every second and used
to update the applicable STEL and TWA calculations which are then checked against the
configured alarm thresholds.
