    • Due to the unstable nature of Chlorine Dioxide (ClO 2 ), Chlorine gas is used as a calibration simulant. If using the MSA calibration system and gas cylinder (P/N 710331), the response ratio is 2:1. In other words, the 2 ppm sample of Chlorine should be set to read 1 ppm of ClO 2 .

  • Page 52 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.

  • Page 53: Figure 2-7. Calibration End Display

    To extinguish the CAL FAULT flag, a complete calibration procedure must be performed. The Ultima X Series Gas Monitor allows automatic zero and span adjustments within a pre-defined range. It cannot make corrections outside this range, such as when an empty or wrong cylinder of gas is applied or failure to begin gas flow within the allotted 30- second countdown occurs.

    No calibration cap or zero gas is necessary. To meet the specification stated, it is necessary to span the oxygen Ultima/Ultima X Series Gas Monitor with the Calibration Kit and an oxygen cylinder. The concentration of oxygen in air varies slightly due to changing relative humidity and pressure levels.
