6. Locate the span gas cylinder and the Calibration Kit Flow
Controller.
7. Screw the Flow Controller onto the top of the span gas cylinder.
8. Locate the Tube Assembly from the cal kit.
9. Push the smaller end of the Tube Assembly over the gas outlet of
the Flow Controller and ensure that the tubing completely covers
the gas outlet.
10.When using Cal Kit 40, connect the other end of the tubing over
the SensorGard inlet.
When using Cal Kit 41, locate the cal cap (with hole for tubing) and
push the tubing through the hole in the bottom of the cap. Then,
connect the end of the tubing over the sensor inlet and push the
calibration cap over the entire sensor inlet.
11. Turn ON the gas flow by turning the flow controller knob.
• It is good practice to have all calibration components
previously assembled.
• Ensure that any calibration gases are applied during the 30-
second count down period.
• If a CAL FAULT indication is on the Ultima X Series Gas
Monitor display before the user is able to apply the gas, a
steady state gas condition was reached, causing the unit to
use a wrong reading as a span indication.
• It is necessary to restart the calibration process to clear this
condition.
12. After the 30 second countdown:
• The display alternates between "CAL" and a value. This value
is the actual reading of the gas concentration the sensor is
detecting.
• Once the gas value on the display is stable, the alternating
display stops. If the calibration is successful, the display will
show END for approximately two seconds. (FIGURE 2-7).
• No user adjustments are necessary.
• The display will show the span gas value while the span gas is
flowing to the unit.
13.Turn OFF the gas flow by turning the knob on the flow controller.
