Calibration

Calibration is the process of applying a known quantity of gas to the transmitter so that the transmitter can adjust the precision and accuracy of the measurements made in normal operating mode. This process ensures that gas measurements are as accurate as possible.

Calibration Warnings - Read before Calibrating

Although ULTIMA X5000 sensors are factory calibrated, another calibration is recommended once the unit is installed in its final environmental destination.

WARNING! 

Use zero gas when zeroing the ULTIMA X5000 transmitter if there is any possibility of background gas. Otherwise, improper calibration could occur.

For optimal sensor performance, allow sensor to acclimate to application conditions for 24 hours before performing an initial calibration.

Perform calibrations 24 hours after initial start up and at a frequency identified in section  Calibration Frequency and Calibration Frequency for XCell Sensors with TruCal and Diffusion Supervision (H2S & CO only).

XCell Sensors with TruCal (CO % H₂S) with Calibration Alert enabled provide an indication for "Calibration Recommended" and "Calibration Required". When either indication is provided by the device, calibrate the sensor.

Failure to follow this warning can result in serious personal injury or death.
