IMPORTANT: Any changes under Settings that are not saved by pressing Enter will be lost after a time-out period of 1
minute. The display will revert to the previous screen without the “Save Successful” intermediate screen.

table values to use for your application.
2.3.3 Changing the User Passcode
As described above the User Passcode is a generic 6-digit code (i.e., not tied to the device ID or Serial No.) with a
factory (default) setting of 111111.
IMPORTANT: The only device settings locked by a device-specific Service passcode are under the Service menu (see
Chapter 3). The end user can adjust all other device parameters shown in the Menu Map in Figure 16.
Since the probe calibration data are protected by the User passcode, we strongly advise the end user to
change the default passcode and make a note of the updated passcode.
Note: The user passcode can be changed as many times as the end user wishes. The new passcode will persist
through power cycling the unit.
This will bring you to a display showing the 4
variables on the 2-point pressure calibration curve.
Choosing the Zero mV and pressing Enter lets you
adjust the Zero mV corresponding to the Zero
pressure, which can be adjusted by choosing the
Zero pressure.
Similarly, you can also adjust the Span mV
corresponding to the Span pressure.
To change the User passcode choose the Change
Passcode option under settings and press Enter.
The next screen lets you set the 6-digit code to any
value of your choice. Press Enter to save the new
passcode.
