Overview of Operating Modes
Suppresses the
warning messages.
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.
Once the last warning has
been cleared, the RANGE
function will be displayed in
the analyzer's main
MESSAGE FIELD.

Viewing and Clearing T300/T300M WARNING Messages
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 10.
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.
