GETTING STARTED M300EU
Addendum to M300E/EM Manual P/N 04288
3.5.3. BASIC CO CALIBRATION PROCEDURE
The initial calibration should be carried out using the same reporting range set up as used during the analyzer’s
factory calibration. This will allow you to compare your calibration results to the factory calibration as listed on
the Final Test and Validation Data Sheet.
Because the M300EU’s analog output setup differs from that of the M300E/EM and because the M300EU
cannot have be modified to include the optional CO
2
or O
2
sensor packages, there are some minor differences in
the initial Calibration procedure as described in Section 3.3 of the M300E/EM Operators Manual (P/N 04288).
These are:
• STEP 1 - SET LIMITS:
• Reporting Range Limit should be set to 50.000 ppm.
• STEP 2 – DILUTION RATIO:
• Ignore this step
• STEP 3 – SET CO SPAN GAS CONCENTRATION
• The CO span gas concentration should be 40.000 ppm
• STEP 4 – ZERO/SPAN CALIBRATION
• Set the display to show the STABILITY test function.
• There is no GAS TO CAL step because the M300EU cannot be modified to include the O
2
and CO
2
sensor packages.
Ignore Sections 3.3.2 and 3.3.3 of the M300E/EM Operators Manual (P/N 04288) since they relate to sensor
options not available on the M300EU.
