Locate and remove the large screw from the side of the AcuDew. The screw
is retained by the sealing gasket.
Ensure that the AcuDew has been powered up for longer than 90 seconds.
Note: Because the AcuDew has been pre-conditioning for a period of time,
the power supply is not likely to be have been recently interrupted.
Rotate the potentiometer counter-clockwise to reduce the read moisture
level, or clockwise to increase the read moisture level. Keep turning until
the indicator displays the correct reading.
Note: If ambient air is being used for the AutoCal, the user will need to
use the best available estimate of the ambient moisture level to complete
the AutoCal procedure.
Note: It is possible, when the potentiometer is first moved, that the
displayed moisture value may jump significantly. This is not a problem:
simply move the potentiometer until the indicator reads the required
value.
Approximately 20 seconds after the last movement of the potentiometer
the indicator will read low range for a second before returning to the
corrected reading, indicating the AutoCal is complete.
Return the screw covering the potentiometer.
9.4.3 Pre-conditioning in normal location
No pre-conditioning of the sensors is required: leave the AcuDew powered up.
9.4.4 Performing an AutoCal in normal location
This type of AutoCal is used when the customer needs to modify the moisture
level reported by the AcuDew.
Locate and remove the large screw from the side of the AcuDew. The screw
is retained by the sealing gasket.
Ensure that the AcuDew has been powered up for longer than 90 seconds.
Note: As the AcuDew is still in its normal location the power supply is not
likely to be have been interrupted.
Rotate the potentiometer counter-clockwise to reduce the read moisture
level or clockwise to increase the read moisture level. Keep turning until the
indicator displays the correct reading.
Note: It is possible when the potentiometer is first moved, that the
displayed moisture value may jump significantly. This is not a problem:
simply move the potentiometer until the indicator reads the required
value.
Approximately 20 seconds after the last movement of the potentiometer
the indicator will read low range for a second before returning to the
corrected reading, indicating the AutoCal is complete.
Return the screw covering the potentiometer.
