Connect Power (6V to 9V) then USB
1. Connect 6V to 9V
DC power here
2. LED should
eliminate as shown.
3. Connect USB
here

Start Software
Should see a quick
update on status
bar and no error
messages.

Select the “4wire_4p096_diode.txt” if needed
This file should be
selected. If it is not, press
the “Select Model File
Emulator File” button and
choose the file.

Run Auto-Cal
1. Check “auto-
continue” to speed
up calibration.
2. Press start.
3. Continue should
start to blink. Press
this to initiate
calibration.

Calibration progress
1. Text describing
the current step is
shown here
2. Measured results will update
here. The sensor emulator will
automatically adjust the “sensor”
output according to the current
emulated temperature and
pressure.

Calibration complete
1. Notice that the calibrated
min and max output are
approximately at the target
of 0.5V to 4.5V. This
indicates that the calibration
worked and the hardware is
functioning correctly

Sensor emulator for verification
Press “run sensor emulator”
on the “Set up cal” tab. This
will bring up the tool on the
right. It will take a few
seconds for the data to load.

Sensor emulator for verification
1. Adjust the sliders to any
temperature or pressure.
2. The cursor position will adjust
to show the current temperature
and pressure conditions on the
sensor curves.
3. The “ideal output” and “Out
Meas” should be approximately
equal. The Error should be less
than 0.1%. In this case the error
is 0.017% so it is working well.
