The base unit functions as a host for the Quick-Select pressure
and temperature modules. The base unit includes two bays for
installation of pressure or temperature modules, an LCD graphic
display with back light, a key pad, a USB micro B receptacle for
communication with a PC, an SD memory card slot and banana
jack connections for DC voltage supply and signal monitoring.
The enclosure is rated to IP65 water resistant.
When pressure and or temperature modules are installed and
the base unit is powered on, it will briefly display the brand name,
data regarding installed modules. Then the HHC will go into mea-
surement mode where it will display up to three values as well as
their respective engineering units of measure. The base unit is
pre-programmed with twelve units of pressure measurement, four
units of temperature measurement, DC voltage 0-30 VDC, DC
current 0-20 ma and also allows the user to program a custom
pressure unit of measure. In measurement mode, the display will
show Battery status, USB connection status, one or two vertical
bar graph indicators indicating percentage of full scale pressure
and other user interface and warning messages when applicable.
The calibrator is equipped with internal memory capable of
storing up to 16,000 records. Datalogs can be transferred to an
optional on board SD memory card to clear internal memory and
allow further data collection. Datalogs can be transferred to a PC
from the SD card and are presented in .csv files which can be
opened by Microsoft Excel software.
