Entering Passwords to Change Analyzer Parameter Settings
To make changes to parameters in CFG or CAL mode, a password must
first be entered. The passwords to enter and work in either mode must
be entered from RUN mode only. Access to CFG mode should be limited
only to trained technicians.
The factory-default password is • • for both modes, but it can be changed
for each mode. If changing a password, it is limited to 9 characters and
can only be changed from CFG mode. If you change the password for
each mode, be sure to record and keep them in a safe place.
If you enter the password incorrectly, the message “<INVALID>” is dis-
played on the User Interface. Carefully re-enter the password.
Changing the Password for CFG / CAL Mode
If changing passwords, pressing Ent will cause the passwords to be
saved in non-volatile memory – the old passwords will be lost. If the
passwords are not saved, the previous passwords will be used follow-
ing a system reset or power-up.
To change the CFG or CAL mode passwords:
1. From RUN mode, press F6 – • • and press Ent to display the CFG
mode screen.
If changing the password for CFG mode, press F6 – (the command to
change the CFG mode password). The message “PSWD1?” appears.
If changing the password for CAL mode, press F6 • (the command to
change the CAL mode password). The message “PSWD0?” appears.
2. Enter a new password (up to 9 characters). The Function keys cannot
be used as part of a password.
3. Press Ent. The new password is entered and the message “PSWD1?”
(CFG mode) or “PSWD0?” (CAL mode) appears again.
4. Enter the new password a second time and press Ent. Press Ent again
to return to CFG mode normal display.
If this password does not match the first entry of the new password,
the message “<UNCHANGED>” is displayed.
