Average Period
Set the time period over which the average will be calculated: Minutes
(1, 2, 3, 4, 5, 6, 10, 12, 15, 20 or 30) or hours (1, 2, 4, 6, 8, 12 or 24) or
rolling hourly averages over the last (4 or 8) hours.
Cal. Average Period
When Enabled can set the time period over which the calibration
average will be calculated when the system is in Cal. Mode SPAN or
ZERO: Minutes (1, 2, 3, 4, 5, 6, 10, 12, 15, 20 or 30) or hours (1, 2, 4, 6, 8,
12 or 24) or rolling hourly averages over the last (4 or 8) hours. Default is
Disabled.
Min. Data Capture
Controls how much of the previous time period needs to be included
before the average yields a number.
The default is 0%, which reflects past behaviour of the instrument:
turning on a machine with 15 minute averaging any time between 1:01 -
1:14 with a setting of 0% would produce #### until 1:15 (because by
1:15, there was at least 1 valid measurement to construct the average
from). However, a setting of 100% would mean the value stayed ####
until 1:30 (because there needs to be a complete 15 minutes worth of
measurements to construct the average from).
Filter Type
Sets the type of digital filter used (None, Kalman, 10 sec, 30 sec, 60 sec,
90 sec, 300 sec or Rolling).
The Kalman filter is the factory default setting and must be used when
using the instrument as a U.S. EPA equivalent method or to comply with
EN certification. The Kalman filter gives the best overall performance for
this instrument.
Rolling Size
[Rolling Filter]
Sets the number of measurements included in the rolling average. Only
available if the Filter Type is set to Rolling.
Backgrounds
The default setting is enabled. When enabled it allows the user to edit
the background interval via the following fields Time, Repeat and Units.
When any of the backgrounds fields are edited the instrument will
automatically calculate the date and time the next background is due to
run and display under each relevant field.
Date
[Backgrounds]
Displays the date that the next background is due to run.
