5.1 Calibration Basics

Series Gas Monitors are calibrated at the factory. Nevertheless, it is
recommended to recalibrate the instrument after installation. The frequency of ca-
libration depends on the duration of use and the chemical exposure of the sensor.
New sensors must be calibrated frequently until it is clear from the calibration data
that they have stabilised. From then onwards, the frequency of calibration can be
reduced and adapted to the plan stipulated by the safety officer or plant manager.
For calibration, some of the following accessories are required [ chapter 8]:

Connect power to the ULTIMA X Gas Monitor at least one hour before
attempting a calibration.
Carry out the calibration during commissioning as well as at regular in-
tervals. This ensures optimum operation of the sensor.
If the XE SensorGard is used during calibration of the combustible sen-
sor a calibration factor 1.2 times higher than the calibration gas concen-
tration must be used.
