MSA Ultima X Series Instruction Manual

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
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 2-6).
• 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.
