To check the detection signal follow the scheme in the picture below. If the signal is less than the value indicated, check the position of
the detection electrode or detector, the electrical contacts and, if necessary, replace the electrode or the detector.
6.9 Checking the detection current (L.P.G.)
To check the detection signal follow the scheme in the picture below. If the signal is less than the value indicated, check the position of
