  If your Riken Keiki Transmitter triggers a gas alarm when there's no leak, it may be due to the presence of interference gas (contact RIKEN KEIKI for actions, such as removal filter), disturbance by noise (turn off and restart the detector head and take measures to eliminate the noise if it occurs frequently), or a sudden change in the environment (take preventive actions to eliminate sudden and frequent environmental changes).

  A persistent rise or drop in the reading on your Riken Keiki Transmitter could be due to several factors: * Drifting of sensor output (perform a zero adjustment). * Presence of interference gas (contact RIKEN KEIKI for information on actions, such as removal filter). * Slow leak (take a remedial measure, i.e., taking actions the same as those for the gas alarm). * Environmental changes (perform the zero adjustment).
