Oxymitter 4000
CALIBRATION RECOMMENDED
alarm signals an IMPS 4000 or SPS
4000 to initiate a calibration. The se-
quencer sends an "in cal" signal to the
control room so that any automatic
control loops can be placed in manual.
Then, the sequencer begins to se-
quence the calibration gases.
3. Manual calibrations must be performed
at the Oxymitter 4000 site and require
operator intervention throughout the
process. Manual calibration instruc-
tions, in condensed form, are on the
inside of the right electronics housing
cover (Figure 9-2). For units with a
membrane keypad, use the following to
perform a manual calibration. For units
with an LOI, refer to paragraph 9-3.
(a) Place control loop in manual.
(b) Verify the calibration gas parame-
ters are correct (paragraph 9-2a).
