6. M300EU OPERATING INSTRUCTIONS
6.1. SUMMARY OF DIFFERENCES BETWEEN OPERATING
THE M300EU AND THE M300E/EM ANALYZERS.
For the most part the operation instruction for the M300EU are the same as those described in Chapter 6 of the
M300E/EM manual (P/N 04288) with the following exceptions:
• There are several additional Test functions related to the optical bench’s convection oven and the A-
REF cycle (see Section6.2.2).
• There is and additional warning message related to the optical bench’s convection oven (see Section
3.4.2)
• There is an additional operating mode, AREF, which can be used to force the instrument to make an
auto-reference measurement and calculation.
• There are several additional iDAS trigger events and parameters (see Appendix A of this addendum).
• The reporting range setup and configuration of the A1 and A2 analog outputs is different (see Section
6.3).
• The optional O
2
and CO
2
sensor packages available for the M300E/EM are not available ton the
M300EU. Ignore all references to these in the M300E/EM Operators Manual (P/N 04288) when
operating the M300EU.
• The set of available VARS is different (see Section 6.5.
• The set of submenus available under the DIAG menu is slightly different (see Section 6.6).
• The set of signals available under the DIAG ÆSIGNAL I/O submenu is different (see Appendix A of this
addendum).
• Because of the difference in how the analog output ranges are implemented between the M300E/EM
and the M300EU, there are some differences in DIAGÆ ANALOG I/O CONFIGURATION submenu
(see Section 6.7.1).
• There are no alarm outputs available of the M300EU. Ignore Section 6.14 of the M300E/EM Operators
Manual (P/N 04288).
• There is an additional STATUS OUTPUT related to the A-REF cycle (see Section 3.3.3).
• The default Hessen protocol gas ID and status flag list is different from that of the M300E/EM (see
Section 6.7.4).
