Pressure/Vacuum .
PRESSURE/VACUUM:
BAROMETRIC 760.1 mmHg
VACUUM 60.5 mmHg
FLOW 21.5 mmHg
RANGE AVG DIAGS ALARM
The Pressure/Vacuum screen (read only) displays the barometric, vacuum,
and flow pressure readings in mmHg. The pressure is measured by a
pressure transducer. The vacuum is the amount of vacuum under the filter
tape. The flow pressure is the pressure differential across the orifice.
Table 2–1. Pressure Units Conversion
Pressure Conversions
mmHg = atm x 0.75006
mmHg = inHg x 25.4
mmHg = hPa x 0.75006
Assuming adequate time has passed for thermal equilibration
(approximately 1 hour), and the vacuum pump has been drawing room air
into the instrument, compare the ambient temperature, sample
temperature, and flow temperature to your NIST traceable thermometer
placed at the inlet tube (see
Figure 2–2 ).
Note Please be sure that the pump exhaust or any other heat source is not
influencing the sensor reading of the temperature/RH cable assembly.
Please be sure the side panel has been removed for at least 60 minutes.
