15.2 Leave the sensor probe in the gland and while the unit is still on, allow it
to achieve equilibrium at the ambient atmosphere in the room. This should
take between two and three minutes. You will know when this has been
accomplished when the numbers on the display begin to stabilize.
16.0 Re-assemble the unit.
16.1 After the calibration process has been completed, remove the sensor
probe from the gland and return it to the sensor-sampling chamber, taking
care to position it properly. The white mark on the sensor probe should face
towards the right of the sensor-sampling chamber (at 3:00 if it were the face
of a clock.). If the white mark is not visible, then it should be placed so the
sample flow directly strikes the face of the mirror on the sensor tip (the
sample flows from right-to-left). In other words, the mirror should face the
incoming gas stream.
16.2 Hand-tighten the black sensor gland to prevent air from leaking out of the
sampling chamber.
16.3 Verify that the system is leak proof by turning on the pump and placing a
finger over the sample inlet port. The flow meter will drop to zero if there are
no leaks. If a leak is detected, make sure that all tubing connections are
tight, especially the black sensor gland.
16.4 After the unit has passed the leak test, the enclosure door can be closed.
17.0 Make sure that all caps are replaced on the calibration salts, and return the
Model1500 VRSD to service.

Startup
The 1500 VRSD unit has been calibrated before shipment from Super Systems Inc. You
can begin typical operation as soon as the unit has been allowed to stabilize in a
temperature similar to the temperature in the heat treating department. This is
particularly important for units that may have been sitting overnight in a delivery van in
sub-zero weather, since the rapid temperature change can cause condensation on the
sensor which will cause the unit to temporarily display inaccurate readings.
