Installation
1. Select Location
Place the Pawkit on a level surface
when measuring to ensure correct
and consistent operation. This
also prevents the risk of spilling
inside the Pawkit. Place the Pawkit
where the temperature remains
fairly stable to avvoid inaccurate
readings.
IMPORTANT: Temperature fluctuations
or vibrations will strongly affect the
accuracy of results.
3. Place Sample
Open the Pawkit sensor cover and
rotate and snap into open position.
Place prepared sample cup on a
level surface. Place opened Pawkit
onto the prepared sample cup.

Verification Versus Calibration
Verification
The Pawkit needs to be verified with a pimary and secondary
verification standard every day. Measuring one standard at the
bottom of a water activity range and one towards the top of the range
will alert the operator to shifts in the calibration.
Calibration
If a shift occurs and the standard is not measuring within
specifications, clean the instrument. If the standard is still not
measuring within specifications, start with the 0.760 standard and
adjust the calibration up or down. Repeat with the 0.250 or 0.920
standard as appropriate. Refer to the
instructions.
NOTE: Adjusting the calibration of the instrument should only be done when the
verification standards are not reading within specifications.
2. Prepare Sample
Take special care when preparing
the sample in order to get the best
readings possible. Always use
clean sampling practices to ensure
accurate and repeatable readings.
Use a homogenous sample, wash
hands thoroughly, fill sample
cup no more than half full, and
clean the sample cup's bottom,
edges, and rim thoroughly with
KIMWIPES strips.
