Setting Up the Password (pass)
The Password menu is used to program a four-digit
password to prevent unauthorized changes to the
programmed parameter settings.
Locking the Meter
Enter the Password menu and program a four-digit
password.
For instructions on how to program numeric values
see Setting Numeric Values, page 19.
Record the password for future reference. If
appropriate, it may be recorded in the space provided.
Unlocking the Meter
If the meter is password protected, the correct
password must be entered in order to make changes
to the parameter settings.
Entering the correct four-digit number sets the
password to 0000, disabling the protection.
Changes to the programmed parameter settings are
allowed only with the password set to 0000.
If the password entered is incorrect, the meter
displays LoCd (Locked) for about two seconds, then it
returns to Run Mode. To try again, press Enter/Ack
while the Locked message is displayed.
Forgot the Password?
The password may be disabled by the following
procedure:
1. Note display reading prior to pressing the Menu
button. Ignore decimal point and sign.
2. Access the Password menu, add 2 to the noted
reading and enter that number as the password
(e.g. display reading = -1.23, password = 0125)

simultaneously or hold the Menu button for
