OPERATION
2. OPERATION
Please read all instructions before operating the PAWKIT to ensure it performs to its
full potential.
PRECAUTIONS
METER products are built to the highest standards, but misuse may damage the
product and possibly void the manufacturer’s warranty. Follow the recommended setup
instructions and arrange proper protections to safeguard products from damage.
2.1 SETUP
Follow the steps listed in Table 1 to set up the PAWKIT and start collecting data.
SAMPLING PRECAUTIONS
Sensor calibration can shift when the PAWKIT is exposed to a variety of volatile substances
or to samples with water activities near 1.00 over a long period of time. To prevent a sensor
calibration shift, always remove samples as soon as the PAWKIT is finished sampling (a beep
signals when it is finished) to avoid damage to the sensor. If a sample is accidentally left
in the chamber for an extended period of time, be sure to check the calibration when the
instrument is used next.

WARNING: The PAWKIT is not intended for outdoor use.
Preparation
Select Clean, Level Location
Always place the PAWKIT on a level surface when measuring to ensure correct
and consistent operation. This also avoids the risk of sample material spilling
inside the instrument and causing contamination.
Place the PAWKIT in a location where the temperature remains fairly stable,
to avoid inaccurate readings (away from air conditioner and heater vents,
windows, etc.)
IMPORTANT: Temperature fluctuations or vibrations will strongly affect the accuracy of
measurement results.
Sample Preparation
Prepare the sample as described in
Section 2.1.1 .
