6.1 5.2.4 Failure in the mains voltage
In case of malfunction of the measuring system or failure in the mains voltage for a
period of up to 72 h, uncontrolled emission of operation and calibration gas shall be
avoided. The instrument parameters shall be secured by buffering against loss
caused by failure in the mains voltage. When mains voltage returns, the instrument
shall automatically reach the operation mode and start the measurement according
to the operating instructions.
6.2 Equipment
No additional equipment is required to test this performance criterion.
6.3 Testing
A failure in the mains voltage was simulated in order to check whether the instrument re-
mains intact and is ready to measure when mains voltage returns.
6.4 Evaluation
The measuring system does not require any operation or calibration gases. Thus, there is no
uncontrolled emission of gases in the case of failure in the mains voltage.
In the event of power failure the measuring system will switch to warm-up mode when the
power supply is re-established. It will remain in this mode until an appropriate and stable
temperature for operation is reached. The time required for warm-up depends on the sur-
rounding conditions at the installation site and on the thermal condition of the instrument it-
self when switched on again. After warm-up the instrument automatically switches back to
the same mode that was active when the power failure occurred. The warm-up phase is indi-
cated by a number of temperature alarms.
6.5 Assessment
When mains voltage returns the measuring system goes back to a failure-free operational
status and automatically resumes measuring.
Does this comply with the performance criterion? yes
