Maintenance
The D
USTTRAK™ DRX aerosol monitor can be maintained in the field using
the instructions below. Additionally, TSI recommends that you return your
D
USTTRAK™ DRX to the factory for annual 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 D
USTTRAK™ DRX is always in good
operating condition.
WARNING
There are no user-serviceable parts inside this
instrument. The instrument should only be opened by
TSI or a TSI approved service technician
Maintenance Schedule
Your DUSTTRAK™ DRX Aerosol Monitor requires maintenance on a regular
basis. Table 4–1 lists the factory recommended maintenance schedule.
Some maintenance items are required each time the D
USTTRAK™ monitor is
used or on an annual basis. Other items are scheduled according to how
much aerosol is drawn through the instrument. For example, cleaning the
inlet sample tube is recommended after 350 hours of sampling a 1 mg/m
3
concentration of aerosol. This recommendation should be pro-rated
according to how the instrument is used. 350 hours at 1 mg/m
3
is the same
amount of aerosol as 700 hours at 0.5 mg/m
3
or 175 hours at 2 mg/m
3
, etc.
