2.4 New sensor calibration/service
Servicing or the fitment of a new sensor can only be undertaken by a suitably trained technician
using the PC software and the appropriate gases.
In addition calibration should be performed as required by local or organisational regulations. In
the absence of suitable evidence, such as a field assessment by a competent person, Crowcon
recommend regular service and calibration every 6 months.
