Configuring the Flowmeter
There are several parameters that can be modified to customize the system. This section describes
how the flowmeter can be customized to best fit requirements.
Password Protection
Before the flowmeter configuration is customized, access to the system parameters must be had.
Two levels of password protection affect access to these parameters.
Factory Level
The highest level of protection requires a system password for access. This password prevents
the user from inadvertently changing variables associated with the system calibration or other
parameters that require factory resources to properly set.
User Level
The second level of protection requires a user password for access. This password provides the
user with the ability to limit access to parameters that affect the way the system operates. The
default user password is 123 and can be changed to any combination of up to 12 characters in
length.
Both levels of password protection can be enabled or disabled. When the system leaves the
factory, the factory level and user passwords are enabled. No password is required to enable a
level of protection, but the appropriate password is required to disable protection.
NOTE: The user password is set to 123 when the system is shipped.
To edit the user password:
1. From the Main Menu press 4. The 4.0 MISCELLANEOUS menu title will appear.
2. Press 3, Password Setup.
3. Press 2, Edit Password.
4. If password protection is enabled enter the current password.
5. Enter the new password of up to 12 characters.
6. When prompted to Save Permanently enter Y for yes.
To enable and disable the password protection:
1. From the Main Menu press 4. The 4.0 MISCELLANEOUS menu title will appear.
2. Press 3, Password Setup.
3. Press 1, Enable/Disable Password.
4. Enter the user password if prompted to do so.
5. The password protection will be toggled on or off depending on its previous state.
Selecting Units of Measure
NOTE: By answering the prompt, Save permanently?, with a N or by pressing the HOME key, the
flowmeter will revert to the previously saved units of measure when the power is cycled.
