PDM3700 Instruction Manual
Thermo Fisher Scientific
The PDM3700 is designed to operate in a position where the instrument
display is oriented at the top of the unit. The sampler includes an
integrated tilt sensor that automatically compensates the measurements
when the position of the monitor moves. This is used to compensate for
the natural motion of the sampler as an operator moves from one location
to another, and is also used to compensate when the vertical orientation of
the sampler changes.
If the sampler is placed or worn in a position where the display is upside
down, the sampler will detect this position and discard the real-time mass
and mass concentration data until this situation is corrected. While the
real-time mass and mass concentration data is discarded during this time,
the instrument will correctly determine the actual collected mass upon
being placed in the proper orientation and resume proper mass and mass
concentration measurements.
The displayed mass and mass concentration values will display the last valid
measurement value and will not change when the sampler is placed in an
inverted orientation.
