6 Using the product
✓ The gas pressure set (0554 1203) must be connected.
✓ The minus connection for differential pressure measurement
must be depressurised at the beginning of measurement
(ambient pressure; the instrument not connected to the system
being checked), as the pressure sensor is zeroed.

The function is only available if the chosen fuel is a gas.
The gas burner capacity is calculated by means of the volume of
gas consumed. To this end, a volume of gas is input into the app
and its consumption read out at the gas meter.
1. Set the volume of gas to watch for at the gas meter.
2. Set the calorific value of the burnt gas.

.
Do not measure for longer than 5 minutes, as the drift of the
pressure sensor could mean that the measured values are
outside the tolerance limits. Re-zero the pressure sensor for
longer measurements.
