Making Changes to a Password Protected Meter
If the meter is password protected, the meter will display the message
Locd (Locked) when the Menu button is pressed. Press the Enter button
while the message is being displayed and enter the correct password to
gain access to the menu. After exiting the programming mode, the
meter returns to its password protected condition.
Disabling Password Protection
To disable the password protection, access the Password menu and
enter the correct password twice, as shown below. The meter is now
unprotected until a new password is entered.
If the correct six-digit password is entered, the meter displays the
message unLoc (Unlocked) and the protection is disabled until a new
password is programmed.
If the password entered is incorrect, the meter displays the message
Locd (Locked) for about two seconds, and then it returns to Run Mode.
To try again, press Enter while the Locked message is displayed.
Did you forget the password?
The password may be disabled by entering a master
password once. If you are authorized to make changes,
enter the master password 508655 to unlock the meter.
