5-1 Preparation
Perform the following preparations before sampling. Inadequate preparation could not
only prevent optimal sampling performance, it could also prevent the sampler from
completing the scheduled sampling time.
(1)
Remove the intake port cap, holder, and extension (for using two types of passive
samplers) and clean them with alcohol. Dry the parts thoroughly after cleaning.
(2)
Reassemble the parts, insert one AA alkaline battery* into the sampler and fasten the
battery cap. After confirming that the LED indicator illuminates and the fan motor
rotates properly, remove the battery.
(3)
Provide mounting equipment appropriate for the intended sampling application. (For
example, provide a lanyard strap for measuring personal exposure or a tripod for
measuring an indoor environment.)
* Orient the battery with the positive (+) terminal toward the main unit and the negative
(-) terminal toward the battery cap. The sampler will not function with the battery
oriented incorrectly. Also, provide a new AA alkaline battery. (Using a battery that is
not a new AA alkaline battery may prevent sampling for 24 hours.) Furthermore,
using a depleted battery could prevent properly coordinating the fan motor and LED
indicator operation.
5-2 Sampling
The method used to install passive samplers differs depending on the type and quantity
of passive samplers being used for sampling. Confirm the sampling method in advance
to install passive samplers correctly.
