CALIBRATION INSTRUCTION
This instrument features a self-calibration function. If the hand-held instrument is used in the air (with no
other object within a 50 cm radius of the machine), the displayed moisture data may not be 0. To perform
a self-calibration, press and hold the "HOLD" button for 3 seconds until the "CAL" symbol appears on the
