nearest 0.1 °C. This thermometer should be referenced to within an
accuracy of ±0.5 °C to NIST-traceable precision thermometers.
Multiple thermometers may be used to cover the temperature range as
long as each thermometer meets the accuracy and readability
specifications described above.
●
A barometer capable of measuring barometric pressure over a range of
600 to 800 mmHg (80 to 106 kilo Pascals [kPa]) and readable to the
nearest 1 mmHg. At least once a year, this barometer should be
calibrated to within ±5 mmHg of a NIST-traceable barometer of
known accuracy.
●
Flow-rate Transfer Standard (FTS) measurement equipment capable of
calibrating, or verifying, the volumetric flow rate measurement with an
accuracy of ±2 percent. This flow rate standard must be a separate,
stand-alone device. It must have its own certification and be traceable
to a NIST primary standard for volume or flow rate. Dry-piston meters
and bubble flow meters should only be used under controlled
laboratory conditions. Ambient field measurements should use a NIST-
traceable low pressure drop orifice/venturi flow meter (such as, BGI
Delta-Cal) or a Streamline Pro™ Model SX Kit (2-25 L/min).
●
A relative humidity (RH) standard capable of measuring in the range of
35-75% RH, readable to the nearest 0.5% RH and accurate to within
2% RH.
Prior to calibration, be sure the Model 5030 i is operating properly. The
Model 5030 i ’s internal diagnostics makes this a quick and simple process.
Turn on the instrument and allow it to stabilize for one hour prior to
calibrating. If you are receiving this instrument for the first time, the
optional acceptance testing in the “
Installation ” chapter should also be
reviewed. If the internal flow temperature sensor requires calibration, the
dynamic heating system should be turned OFF, the cover should be
removed, and the instrument should sample room temperature air at least
one hour prior to calibrating.
The order of calibration described below is preferred for optimal
performance of the 5030
i and comes from many years of experience
working with and developing ambient particulate monitoring
instrumentation. The Calibration submenus allow the user to view and
calibrate the instrument. All calibration submenus are visible only when the
instrument is in service mode. For more information on the service mode,
see “
Service Mode ” earlier in Chapter 3.
