Cal Time
Cal Purge
Cal time is the time of day of the automatic calibrations. This time is in
24 hour format HH:MM, where HH is hour and MM is minute. Interval
is the time interval in days between automatic calibrations. This field
has preset intervals to choose from. Calibrations can be run at intervals
of 1 day, 7days, 14 days, and 30 days. To change these settings move the
cursor to the interval field, the toggle menu label will appear. Press the
toggle key to switch between the preset values.
Cal Purge is the amount of time the analyzer opens the purge valve and
allows calibration gas to flow through and purge the line. The purge
field has preset values of 1 minute, 6 minutes, 13 minutes, and 21 min-
utes. Purge time must allow enough time to fully purge the supply line
of the calibration gas. Failure to completely purge the supply line will
result in significant discrepancies between the real concentration and the
reported concentration.
Cal Tol is the tolerance of the calibration run. If the calibration difference
from the previous calibration run is within the set tolerance range the
instrument will automatically update the calibration response factor.
If the calibration settings are not within the set tolerance range, the
status LED will turn red and the settings will not be updated. To manu-
ally update these settings move the cursor in front of the gas name and
press the Accept key. To permanently save the changes see the Saving
Changes into non-volatile Ram section of this manual.
From the main menu, pressing the Calib key will begin a manual calibra-
tion run of the ta7000R. The analyzer does not need zero calibration. An
