Note 1. The microprocessor board 01100915 may be replaced with 01100918, 01100918A
01100918B, 01100918C or 01100918D providing that the correct software is fitted, see
Table 6.2.
Note 2. When the 01100925B is replacing an 01100925A, remove link N-M and install link L-N.
This is also necessary if the uncalibrated oxygen reading is greater than the high
tolerance limit for the span calibration gas.
Note 3. The 01100918D is fitted as standard to ISSEP INIEX purged units, and MUST be
replaced with an S1100918D only.
