  • Page 26: Calibration Basics

    Chapter 2, Start-up and Calibration Calibration Basics While the Ultima X Series Gas Monitor is factory-calibrated, it is good practice to calibrate the unit once it is installed in its final environmental destination. As with any type of gas monitor, the only true check of its performance is to apply gas directly to the sensor.

During a regular calibration, the Ultima X Series Monitor automatically begins the span countdown after a successful zeroing of the unit. The span countdown is 30 seconds (FIGURE 2-5).
  • Page 32 • 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.

  • Page 43: Chapter 4 Maintenance

    Chapter 4, Maintenance Chapter 4 Maintenance General The Ultima X Gas Monitor is constantly performing a self-check. When a problem is found, it displays the appropriate error message. (Table 4-3, "Troubleshooting Guidelines"). When a critical error is detected within the unit, the output signal goes to a fault condition.

  • Page 44: Caution

    Replacing an Ultima XE or Ultima XA Sensor The only routine maintenance item is the sensing element itself, which has a limited lifetime. When the Ultima X Series Gas Monitor’s read-out indicates that the sensor must be changed, there is very little sensor lifetime remaining. It is good practice to obtain a replacement sensing element before the sensing element within your unit becomes inoperative.
