Necessary equipment Multimeter (ranges 0-30 mA and 0-2 V), intrinsically safe if necessary. Cylinder of pure air.

  • Page 24: Stabilization Time

    Stabilization time After mounting, it is essential to allow the detector temperature to stabilize. In addition, after turning the power on, certain sensors require a further pre-h e a ti n g time. Any adjustment before the time indicated will result in an incorrect measurement, which may in turn compromise the safety of the goods and personnel.

Place the calibration cup on the detector head (Figure 13, "A"). 3. Connect the calibration cup to the calibration gas cylinder "D" by using a flexible hose "B".

  • Page 27: Calibrating The Olct 100

    Calibrating the OLCT 100 Wait for the stabilization time on power-up. For a LEL detector, it is recommended to calibrate with the targeted gas. Should the operator calibrate with another gas, please refer to tables on pages 28 to 30 to know the recommended calibration gas and the cross sensitivity factor.
