Configurations can be used to save time in setting up parameters for specific calibration needs. For
example, there may be a requirement to calibrate a
0 …
100 psi transducer, and an upper limit of 105
psi cannot be exceeded and the rate of pressure change cannot exceed 5 psi per second. These
parameters can be set and assigned (saved) in one of the configuration numbers and recalled
(loaded) before this test is run.
7.3.2 Sensor Tab
Within the [Sensor] tab of the Setup [
] menu are parameters that are associated with all of the
installed pressure transducers. Settings chosen here will affect the indicated and remote output of the
instrument’s pressure reading.
Sensor Filter
In the [Sensor] tab in the Setup [
] menu there is a button labeled [Filter]. The right side of the
[Filter] button shows the current filter setting. The sensor filter acts on the output pressure indicated on
the instrument, filtering out small pneumatic and electrical variations in the pressure transducer output.
This is done by mathematically smoothing the output reading using a low pass filter on the electrical
output of the pressure transducer. The filter can be set to Off, Low, Normal or High simply by pressing
the associated button on the right site of the menu.

Resolution (display digits)
In the [Sensor] tab in the Setup [
] menu there is a button labeled [Resolution]. The right side of
the [resolution] button shows the current resolution setting with a blue button. The display resolution
for the pressure output can be chosen from this side bar selection menu. The resolution is the number
of digits that will be shown in the pressure indication within all screens of the instrument. The user can
change the resolution to 4, 5 or 6.
