To view and clear warning messages:
Suppresses the
warning messages.
Press
CLR
to clear the current
message.
If more than one warning is
active, the next message will take
its place.
Once the last warning has
been cleared, the
RANGE
function will be displayed in
the analyzer’s main
MESSAGE FIELD.
NOTE:
If a warning message persists after
several attempts to clear it, the message
may indicate a real problem and not an
artifact of the warm-up period.

CALIBRATION MODE
Pressing the CAL button switches the T300/T300M into calibration mode. In this mode
the user can calibrate the instrument with the use of calibrated zero or span gases. This
mode is also used to check the current calibration status of the instrument.
•
For more information about setting up and performing standard calibration
operations or checks, see Section 9.
•
For more information about setting up and performing EPA equivalent calibrations,
see Section 9.8, EPA Protocol Calibration.
If the instrument includes one of the available zero/span valve options, the
SAMPLE
mode display will also include
CALZ
and
CALS
buttons. Pressing either of these
buttons also puts the instrument into calibration mode.
•
The
CALZ
button is used to initiate a calibration of the analyzer’s zero point using
internally generated zero air.
•
The
CALS
button is used to calibrate the span point of the analyzer’s current
reporting range using span gas.
For more information concerning calibration valve options, see Table 1-1.
For information on using the automatic calibration feature (
ACAL
) in conjunction with
the one of the calibration valve options, see Section 9.4.

It is recommended that this span calibration be performed at 80-90% of
full scale of the analyzer’s currently selected reporting range.
EXAMPLES: If the reporting range is set for 0 to 50 ppm, an appropriate
span point would be 40-45 ppm. If the of the reporting range is set for 0
to 1000 ppb, an appropriate span point would be 800-900 ppb.
