Maintenance
You can perform routine maintenance on the P-T
RAK
® particle counter using
the instructions below. However, you are not able to perform field
calibration of the instrument. For this reason, TSI recommends that you
return your P-T
RAK
® particle counter to the factory for annual cleaning and
calibration. For a reasonable fee, we will quickly clean and calibrate the unit
and return it to you in “as new” working condition, along with a Certificate
of Calibration. This “annual checkup” helps ensure that the P-T
RAK
® particle
counter is always in good operating condition.
Note: There are no user-serviceable parts inside this instrument.
Opening the instrument case may void the warranty. TSI
recommends that you return the P-T
RAK
® particle counter to
the factory for any required maintenance or service not
described in this manual.
