Calibrating the OLCT100
Zeroing (OLCT100)
Proceed as follows:
038
Figure 18 : Zeroing (OLCT100).
Inhibit any alarm signals on the central unit.
2. Insert the blue and green plugs on the measurement lead into the + and -
multimeter sockets, respectively (0-2 V range or similar) (Figure 18, "H")
3. Insert the measurement lead plug into connector "A".
4. Place the calibration shroud on the detector head ("D").
5. Connect the calibration shroud to the pure air bottle "G" by using a flexible
hose "E".
6. Open the valve "F" on the pure air bottle (flow rate 30 to 60 litres/hr).
7. After the measurement has stabilized (approx. 2 minutes), read the value on
the multimeter "B".
A measurement of 0.4 V corresponds to 4 mA, i.e. 0% gas.
Note: for the oxygen detector, inject pure nitrogen instead of air.
