A value of "XXXX" displayed for any of these TEST functions
Sample Pressure measurements are represented in terms of
ABSOLUTE pressure because this is the least ambiguous method
Absolute atmospheric pressure is about 29.92 in-Hg-A at sea
level. It decreases about 1 in-Hg per 1000 ft gain in altitude. A
variety of factors such as air conditioning systems, passing
storms, and air temperature, can also cause changes in the

6.2.3. Calibration Functions

Pressing the CAL key, switches the M400E into calibration mode. In this mode the
user can with the use of calibrated zero, or span gases calibrate the Zero and Full
Span points of the analyzer's measurement range.
If the instrument includes one of the available Zero/Span Valve options the Sample
Mode display will also include CALZ and CALS keys. Pressing either of these keys
also put the instrument into Cal Mode. The CALZ key is used to initiate a calibration
of the analyzer's Zero Point. The CALS key is used to calibrate the Span point of
the analyzer's current measurement range. It is recommended that this Span
calibration be performed at 80% of full scale of the analyzer's Measurement Range.
