Calibration Gas Solenoids
The solenoids sequence the calibration gases. One solenoid controls
calibration gas 1 (high calibration gas), and the other controls calibration gas
2 (low calibration gas). The solenoids activate and deactivate to allow the
calibration gases to flow between the sequencer and Oxymitter 4000.
Pressure Switch
The pressure switch detects if the pressure of a calibration gas is low, which
can be caused by an empty gas bottle, a disconnected gas line, etc.
Calibration is prohibited when calibration gas pressure is low.
Circuit Board
The circuit board converts the incoming line voltage from AC to DC for use by
the solenoids, terminations, and the programmable logic device. The power
circuit is protected by a 1.6 A, 250 V, fast acting fuse.
The board contains a programmable logic device (PLD) that has the
electronics to energize and deenergize the solenoids based on a signal from
the Oxymitter 4000.
A terminal strip provides convenient access for all signal and power user
connections.
Calibration Gas Flow Meter
The calibration gas flow meter indicates the flow rate of calibration gas flowing
to the Oxymitter 4000.
Reference Air Flow Meter
The reference air flow meter indicates the amount of reference air
continuously flowing to the Oxymitter 4000.
Pressure Regulator
The pressure regulator ensures the instrument air (reference air) flowing to
the Oxymitter 4000 is at a constant pressure [20 psi (138 kPa)]. The regulator
also has a filter to remove particulates in the reference air and a drain valve to
bleed the moisture that collects in the filter bowl.

SPS 4001B
THEORY OF
OPERATION
The Oxymitter 4000 is one of the few instruments found in industry that permit
the permanent piping of a calibration standard into the probe. Most
instruments measuring pressure, flow, or temperature, require that a
calibration standard be brought to the instrument or that the instrument be
taken to the calibration source in the instrument shop.
The permanent calibration gas connections allow for autocalibrations to occur
without operator intervention. The following paragraphs describe how an
Oxymitter 4000 is autocalibrated when used with the SPS 4001B.
In addition to the calibration methods available via the Oxymitter 4000
keypad, HART communicator, AMS software, or a remote contact, the SPS
4001B works in conjunction with the Oxymitter 4000's CAL RECOMMENDED
feature to perform an autocalibration.
This feature automatically performs an impedance check every hour on the
Oxymitter 4000. If a calibration is recommended and its contact output signal
is set for "handshaking" with the SPS 4001B sequencer, the Oxymitter 4000
sends a signal to the sequencer. The sequencer automatically performs a
calibration upon receiving the signal. Therefore, no human interface is
required for the automatic calibration to take place.
See Figure 1-3. When a calibration is required, the Oxymitter 4000 sends a
signal to the programmable logic device (PLD) on the interface board of the
sequencer. The PLD energizes the calibration gas 1 (high O2) solenoid.
Calibration gas 1 then flows through the sequencer to the Oxymitter 4000.
The Oxymitter 4000 measures the oxygen content of calibration gas 1 and
sends a signal to the sequencer indicating that it received the gas. When the
sequencer receives the signal, the PLD deenergizes the calibration gas 1
solenoid.
Next, the PLD energizes the calibration gas 2 (low O2) solenoid, and
calibration gas 2 then flows through the sequencer to the Oxymitter 4000. The
Oxymitter 4000 measures the oxygen content of calibration gas 2 and sends
a signal to the sequencer indicating that it received the gas. After measuring
the two calibration gases, the Oxymitter 4000 automatically makes an internal
calibration adjustment and sends the signal to the sequencer. When the
sequencer receives the signal, the PLD deenergizes the calibration gas 2
solenoid.

GAS CONNECTIONS Use the following procedures to connect the reference air and the calibration
gases.
Reference Air (Figure 2-1)
The Oxymitter 4000 requires a source of reference air that is constantly
20.95% O2. Clean and dry instrument air provides the most stable source of
reference air. If instrument air is unavailable, the reference air port of the
probe can be left open, permitting ambient air to passively diffuse into the
probe.
1. Connect the instrument air supply to the INST AIR IN port of the
manifold.
2. The pressure regulator is factory set at 20 psi (138 kPa). If necessary,
readjust by turning the knob on the top of the regulator until the desired
pressure is obtained.
3. Next, connect the reference air from the REF GAS OUT port of the
manifold to the REF GAS port on the Oxymitter 4000.
Calibration Gas (Figure 2-1)
1. Connect O2calibration gas 1 (high calibration gas) to the HI GAS IN
port on the manifold. Ensure the calibration gas pressure is set at 20 psi
(138 kPa).
2. Connect O2calibration gas 2 (low calibration gas) to the LOW GAS IN
port on the manifold. Ensure the calibration gas pressure is set at 20 psi
(138 kPa).
3. Connect the calibration gas from the CAL GAS OUT manifold fitting to
the check valve connected to the CAL GAS port on the Oxymitter 4000.
Instrument air is not recommended for the high calibration gas. Do not use 100% nitrogen
as a low gas (zero gas). It is suggested that the low (zero) gas be between 0.4% and 2.0%
O2. Do not use gases with hydrocarbon concentrations of more than 40 parts per million.
Failure to use proper gases will result in erroneous readings.

OVERVIEW This section specifies the requirements to set up an Oxymitter 4000
calibration and how to verify the calibration gas flow setup. It also explains the
differences between automatic and semi-automatic calibrations and how to
initiate them.
CALIBRATION
REQUIREMENTS
Calibration Gas Tanks
Two tanks of precision calibration gas mixtures are required. Recommended
calibration gases are nominally 0.4% and 8.0% oxygen in nitrogen.
Do not use 100% nitrogen as a low gas (zero gas). It is suggested that gas for the low (zero)
be between 0.4% and 2.0% O2. Do not use gases with hydrocarbon concentrations of more
than 40 parts per million. Failure to use proper gases will result in erroneous readings.

Check Valve
A check valve is required at the Oxymitter 4000 (between the calibration fitting
and the gas line) to prevent the migration of process gases down the
calibration gas line between calibrations.
A typical calibration setup for the Oxymitter 4000 is shown in Figure 1-3.
