Oxymitter 5000
will flash continuously. The
flashing indicates the Oxy-
mitter 5000 is ready to take
readings using the second
calibration gas.
5
Remove the first calibration
gas and apply the second
calibration gas. (Electronics
will abort the calibration if step
6 is not done within 30 min-
utes).
6
Push the CAL key; the CAL
LED will be on solid. The timer
is activated for the second
calibration gas flow. When the
timer times out, the CAL LED
will flash a 2 pattern flash or a
3 pattern flash (2 pattern flash
equals a valid calibration, 3
pattern flash equals an invalid
calibration).
If the slope or the constant is
out of specification, a diag-
nostic alarm LED will be
flashing. The diagnostic alarm
will remain active until the
purge cycle is over. If the
three pattern flash occurs
without a diagnostic alarm, the
calibration gases could be the
same or the calibration gas
was not turned on.
The CAL LED flashing indi-
cates the calibration is done.
(See Section 5, TROUBLE-
SHOOTING, for an explana-
tion of the 2 pattern and 3
pattern flashes).
7
Remove the second calibra-
tion gas and cap off the cali-
bration gas port.
8
Push the CAL key; the CAL
LED will be on solid as the
unit purges. (Default purge
time is three minutes). When
the purge is complete, the
CAL LED will turn off.

Instruction Manual
If the calibration was valid, the DI-
AGNOSTIC ALARMS LEDs will in-
dicate normal operation. If the new
calibration values, slope or con-
stant, is not within the parameters,
the DIAGNOSTIC ALARMS LED
will indicate an alarm. (See Section
5, TROUBLESHOOTING, for alarm
codes). If the calibration was inva-
lid, the Oxymitter 5000 will return to
normal operation, as it was before
a calibration was initiated, and the
parameters will not be updated.
(e) Place control loop in automatic.
c. FOUNDATION fieldbus O
METHOD
To perform a calibration using FOUNDA-
TION fieldbus, use the following procedure.
1. From the computer running the fieldbus
control program, run the O
Method.
Failure to remove the Oxymitter 5000
from automatic control loops prior to
performing this procedure may result
in a dangerous operating condition.
2. In the first O
CAL screen, a "Loop
2
should be removed from automatic
control" warning appears. Remove the
Oxymitter 5000 from any automatic
control loops to avoid a potentially
dangerous operating condition and
press OK.
3. From this point, follow the on-screen
prompts to complete the calibration
procedure. When a step is complete,
select Proceed to Next Step and press
the Next button.
4. During the wait periods, such as during
a purge, the Time Remaining display
may be updated by selecting Update
and pressing the Next button.
