CALIBRATION GAS FLOW SETUP
After installing the SPS 4000 as described in
Section 2, calibrate the Oxymitter 4000 to verify
SPS 4000 operation and the communication link
between the sequencer and Oxymitter 4000.
a.
Verify that both calibration gases are con-
nected to the SPS 4000. Also verify that the
pressure regulators on both calibration gas
bottles are set to 20 psig (138 kPa gage).
b.
Initiate a semi-automatic calibration using
one of the methods specified in paragraph
3-5.
NOTE
Only set the calibration gas flowmeter
upon initial installation and after
changing the diffusion element in the
Oxymitter 4000. Refer to the flowmeter
adjustments in Section 4 for more in-
formation.
c.
As the Oxymitter 4000 and SPS 4000 apply
the first calibration gas, set the calibration
gas flowmeter to 5 scfh. During the applica-
tion of the second calibration gas, verify that
the flowmeter reads 5 scfh. If not, adjust the
pressure regulator on the second calibration
gas bottle so the 5 scfh flow is provided.

AUTOMATIC CALIBRATION
Automatic calibrations require no operator ac-
tion and can be performed through the Oxymit-
ter 4000 CAL RECOMMENDED feature or
through scheduled time intervals that can be
programmed through the HART/AMS for the
Oxymitter 4000. In addition, the calibration
gases must be permanently piped to the Oxy-
mitter 4000.
a. CAL
RECOMMENDED
If the Oxymitter 4000 is configured for
handshake mode with the SPS 4000, the
Oxymitter 4000 can initiate a calibration by
sending a signal to the sequencer when the
CAL RECOMMENDED LED activates. To
enable handshake mode, the Oxymitter
4000 logic I/O must be set for mode 8.
Handshake mode is configured at the fac-
tory or can be accessed through HART/
AMS. Refer to the logic I/O information in
the HART/AMS section of the Oxymitter
4000 Oxygen Transmitter Instruction Bulle-
tin for more information.
b. Timed
Interval
An automatic calibration can also be pro-
grammed to occur at a specific time interval,
in hours, using the HART communicator or
AMS software. Refer to the HART/AMS
section of the Oxymitter 4000 Oxygen
Transmitter Instruction Bulletin for this
procedure.

SEMI-AUTOMATIC CALIBRATION
Semi-automatic calibrations are operator initi-
ated and can be performed using the Oxymitter
4000 keypad, HART handheld communicator/
AMS software, or a remote contact. In addition,
the calibration gases must be permanently
piped to the Oxymitter 4000.
a. Oxymitter
4000
Keypad
A semi-automatic calibration can be initiated
by pressing the CAL button on the Oxymit-
ter 4000 keypad. For more information, re-
fer to the Oxymitter 4000 Oxygen
Transmitter Instruction Bulletin.
b. HART
Handheld
Communicator/AMS
Software
A semi-automatic calibration can be initiated
by connecting the HART handheld commu-
nicator, or AMS software, to the Oxymitter
4000 4-20 mA signal line and using the
HART communicator keypad or computer
keyboard to access the applicable calibra-
tion menu. Refer to the Oxymitter 4000
Oxygen Transmitter Instruction Bulletin or
the available HART documentation for more
information.
c. Remote
Contact
A semi-automatic calibration can be initiated
using a remote contact such as a cus-
tomer’s control system. The remote contact
processes the calibration command on a
PC and sends the signal to the Oxymitter
4000. For more information on remote-site
calibrations, refer to the documentation for
the system in use.
