A special mode has been included in the unit to provide the ability to calibrate the
instrument as well as set advanced Parameters. The Calibration Mode is entered by
depressing both the SETUP and UP keys simultaneously while in the Setup Mode. After
matching the access code, the first parameter and the current value will alternately flash in
the display. The SETUP key is then used to step through the parameters. The following
table indicates the Parameters that are available, their meaning and available setting range:
PARAMETER
FCNT
PCLO
PCHI
TCLO
TCHI
CODE
FCNT – This sets the band over which the digital filter is active. If the pressure reading
change (direct A/D counts) is greater than this setting, the digital filter is bypassed,
providing a quick response to step changes in pressure. (Factory default = 16)
PCLO – This is a READ ONLY parameter that shows the internal zero calibration setting of
the A/D converter for pressure measurements.
PCHI – This is a READ ONLY parameter that shows the internal full scale calibration
setting for the A/D converter for pressure measurements.
TCLO – (MODEL 1300 ONLY) This is a READ ONLY parameter that shows the internal
zero calibration setting of the A/D converter for temperature measurements.
TCHI – (MODEL 1300 ONLY) This is a READ ONLY parameter that shows the internal full
scale calibration setting for the A/D converter for temperature measurements.
CODE – This is the value that must be matched to gain entry into the Calibration Mode.
