Let’s take the upper value as an example:
Apply to the input as the upper value a pressure of 25.400 mmH
2
O and wait until the readout of
pressure stabilizes. Then, write the upper value as, for example, 25.400 mmH
2
O in parameter
CAL_POINT_HI. For each value written a calibration is performed at the desired point.

WARNING
It is recommendable, for every new calibration, to save existing trim data, by means of parameter
BACKUP_RESTORE, using option "Last Cal Backup".
Via Local Adjustment
In order to enter the local adjustment mode, place the magnetic tool in office “Z” until flag “MD” lights
up in the display. Remove the magnetic tool from “Z” and place it in orifice “S”. Remove and reinsert
the magnetic tool in “S” until the message “LOC ADJ” is displayed. The message will be displayed
during approximately 5 seconds after the user removes the magnetic tool from “S”. Let’s take the
upper value as an example:
Apply to the input a pressure of 25.400 mmH
2
O.
For this case, a
sensor range 3
is used: The
URL is 25400
mmH2O or
1000 inH2O.
The Upper Calibration
Point should be
entered. This value
must be inside of the
Sensor range limits
allowed for each type
of sensor.
After the calibration,
the user can see the
result for this process.
For this case, a sensor
range 3 is used: The
LRL is -25400
mmH2O or
-1000 inH2O.
The Lower Calibration
Point should be entered.
This value must be
inside of the Sensor
range limits allowed for
each type of sensor.
After the calibration, the
user can see the result for
this process.
