Equipment Required - MSA Ultima X Series Installation & Maintenance Instructions Manual

• Due to the reactivity of HCL with flow system components, the flow
control regulator must only be used for HCL gas. HCL gas must be
run through the flow control regulator and tubing for five minutes
before attempting a calibration. After a successful calibration, flush
the flow control regulator and tubing with 100% Nitrogen for five
minutes. Store the flow control regulator in the desiccated bag
included in Calibration Kit 54 or equivalent dry container.

Equipment Required

Three calibration kits (numbered 40, 41, and 54) are available from
MSA for diffusion Ultima X Series Gas Monitors. Kit 40, 41, and 54 are
housed in a convenient carrying case and contain all items necessary
(less gas) for a complete and accurate calibration.
These Kits do not calibrate Ultima X Series units equipped with a flow
cap.
NOTE: The calibration procedure for the sample draw Ultima XE/XA
Monitor is the same as the procedure for the diffusion version,
except calibration gas is applied to the calibration entry port of
the inlet flow block and the cal kit for pumped units provides a
flow matching regulator.
The check or calibration gases can also be carried in the case. See
TABLE 2-2 for the appropriate zero and span gas cylinders for your
Ultima X Series Gas Monitor.
TABLE 2-2 shows the recommended calibration kit for Ultima X Series
Gas Monitors. Typically, Cal Kit 41 uses 0.25 LPM regulator and a
calibration cap to contain the calibration gas. Cal Kits 40 and 54 use a
1.5 LPM regulator and no calibration cap. If Cal Kit 41 is recommended
and the application is such that the calibration cap cannot be used
(such as for a remote sensor application), Cal Kit 40 may be used.
However, any time Cal Kit 40 is used, ambient wind conditions must be
minimized to avoid a calibration with increased sensitivity.
NOTE: The Ultima XIR uses Cal Kit 40 and does require a calibration
cap. This calibration cap (P/N 10041533) is shipped with the
product.
