DP2000 Portable Dew Point Analyzer Operations Manual
2.1 The microprocessor board is located in the front left side of the unit.
This board contains three very small buttons that are used for
calibration. Two are next to one another, and they are marked "75.3%"
and "11.3%", while the other has no label. The unmarked button is the
"Calibrate" button. The approximate locations of each button are
shown on this diagram:
2.2 The sensor-sampling chamber is located in the back left of the unit.
It is the gray rectangular box with brass barb fittings on either side
with a black plastic gland protruding from the center.
2.3 The sensor probe is positioned in the sensor-sampling chamber. It
is held in place by the nut on the black plastic gland.
3.0 Remove the sensor probe from the sensor sampling chamber.
3.1 Loosen the black plastic gland nut and slowly slide the sensor probe
out through the airtight seal. Care must be taken when removing this
sensor probe, since the tip is very delicate and can be easily damaged
if it is mishandled. Note that the probe has white mark at the wire
entry point, which must be aligned with corresponding white mark in
plastic gland when it is re-inserted in the sampling chamber.
4.0 Install the sensor probe into the 75.3% salt solution.
4.1 Slip the black sensor gland (supplied in the calibration kit) over the
sensor probe with the sensor tip protruding from the threaded end of
the gland and the sensor wires being flush with the top of the rubber
