Result
:
is the result of the tightness test.
Compliant (piping suitable for operation):
when the leakage flow calculated in the reference
conditions is not greater than 1 dm
3
/h for methane and not greater than 0,4 dm
3
/h for LPG the
system is authorized to operate without restrictions or intervention.
Compl. 30 DD (piping temporarily suitable for operation):
when the leakage flow calculated in
the reference conditions is included in the range 1 dm
3
/h < Qref ≤ 5 dm
3
/h for methane and in the
range 0,4 dm
3
/h < Qref ≤ 2 dm
3
/h for LPG. The system is authorized to operate only for the time
needed for the maintenance of the pipe in order to fix the leakage problem, and in any case for no
more than 30 days after the testing day. Once the fixing has been completed the piping must tested
again for its tightness according to the UNI 7129 standard.
Non compliant (not suitable for operation):
when the leakage flow is greater than 5 dm
3
/h for
methane and greater than 2 dm
3
/h for LPG. In this situation the measured leakage is such that the
piping is not suitable for operation and must immediately placed out of order. Once the leakage
problem has been fixed the piping must tested again for its tightness according to the UNI 7129
standard
TcK Temperature:
The user can measure the temperatures within the range specified in the technical specifications (e.g. plant
delivery temperature) by using an OPTIONAL Type K thermocouple contact probe connected to the TcK input.
Pt100 Temperature:
The ambient temperature can be measured within the range specified in the technical specifications by
connecting the remote air temperature probe provided with the instrument to the Pt100 input.
Ioniz. current:
It is possible to measure the ionization current of a boiler and check its value depending on the boiler’s technical
features by connecting the ionization probe (optional) to the serial cable socket (visible in
O
on page 10).
