Password Passwd
Basic Function
Password protection prevents unauthorized users from changing programming information. Initially, the password is set to
all zeros. If the current setting requires a change, press ENTER at the Passwd prompt. The first digit of the password begins to
flash. Use ▲ to increment the digit until it matches the first number of the required password. Use ► to advance to the next
digit of the required password value then use ▲ to increment the display digit until it matches the next digit of the required
password. Repeat this step for the all the digits of the password and then press ENTER to save the new password and advance
to the next parameter.

Basic Function
Reset password parameter prevents unauthorized users from manually resetting the flow monitor’s main totalizer. Initially, the
password is set to all zeros. To change the reset password, press ENTER at the RstPswd prompt. The first digit of the password
begins to flash. Use ▲ to increment the digit until it matches the first number of the required password. Use ► to advance to
the next digit of the required password value then use ▲ to increment the display digit until it matches the next digit of the
required password. Repeat this step for the all the digits of the password and then press ENTER to save the new password and
advance to the next parameter.
OTE:N Entering a password in the Passwd screen and leaving the password blank in the RstPswd screen allows for total resets
(not requiring a password), but restricts programming modification.
