NOTE: The SCAN mode will give relative readings only, not %MC. The numbers displayed
represent the relative dryness or wetness of the material on a scale of 0 to 300. In
order to accurately interpret your readings, first establish a baseline reading by taking
a reading in an area you know to be unaffected or dry, then take a reading in the
affected or wet area and compare the two readings.

1. To access alarm settings, press the ALARM KEY three times.

3. After the alarm is turned on, use the SCAN ( ð) key to increase the alarm value, and the
PIN ( ï) key to decrease alarm value.

Press the center HOLD (SELECT) KEY to return to SCAN mode.
