REPORTS Setup Screen
– Daily Data and Dynamic Ranges
The SETUP > Reports screen provides options for setting the hours of the daily data average
period and the type of dynamic range being used.
6.11.1
Daily Data Range
The DAILY RANGE field is used to select which hours are included in the daily BAM 1020
data file reports. The two possible choices are:
00:00 to 23:00
(old default setting) or
01:00 to 24:00
(correct newer setting)
The BAM 1020 time stamp is the end of the sample hour, not the beginning, so the 01:00
data point is for air sampled between midnight and 1:00 am. Always select 01:00 to 24:00
unless the monitor is being used in a special application requiring 00:00 to 23:00.
6.11.2
Dynamic Range
The DYNAMIC RANGE field is used to choose the range of the concentration value being
stored in the data logger. The two possible choices are
STANDARD
or
EXTENDED.
Both settings will utilize the same OFFSET value configured in the SETUP > SAMPLE
screen. See section 6.2 for details on setting the OFFSET value.
The STANDARD range sets the logger scaling to match the analog output range as
determined using the RANGE setting in the SETUP > SAMPLE screen. See section 6.2 for
details on setting the RANGE value.
Choosing the EXTENDED range forces the logger scaling to be 10 mg, regardless of the
analog output RANGE setting. The EXTENDED range is automatically selected when setting
the HJ 653 option (see section 6.12) to YES.
Most locations will use the STANDARD range. However, areas with heavy concentrations (or
where local regulations may require it) should use the EXTENDED option.
Note: Changing this setting will clear all data stored in memory. Be certain to download and
save any collected data prior to changing the range.
