• The gas must be delivered at ambient pressure (i.e., do not push gas into the leak
detector). The normal way to accomplish this is to create an open connection
between gas container and detector inlet so that the excess calibration gas is
vented to the ambient. This exhaust should be placed outside the test room,
preferably outdoors.

ð Select the calibration to perform and click the check mark button.
ð The leak detector leads you through the process by indicating which gas to
deliver to the detector in each step. Make sure that no residual gases are
present in the ambient during Fresh Air step. Most common problems occur if
you used 2.2 Vol% or 100 Vol% methane shortly before the trying to calibrate
with 10 ppm or 100 ppm methane.

A successful calibration is confirmed by a green check mark.
ð
A failed calibration is indicated by a red cross.
You can continue to use the leak detector even if calibration failed. The previous
calibration parameters are restored.
6.2.15.2 Setting of calibration gas concentrations
Accuracy can be affected by calibration gas tolerance.
For optimum performance adjust the concentrations of the calibration gases set in the
leak detector to the actual composition of your calibration gases.
For optimum performance of your leak detector you should use the proposed
calibration gases. The exact concentrations of the gas delivered often deviates slightly
from these values due to tolerance factors etc. The exact value is typically stated on
the analysis certificate of the respective gas. You should therefore adjust the
concentrations of the calibration gases set in the detector to match the actual
composition of your calibration gases, see "Concentration of calibration and test gases
