needed characteristics of the meter .
To enter the mode, press the SETUP key and
enter the password when the device is in idle

If the correct password is not entered, the user can only
view the setup parameters (except for passwords) without
modifying them (and the device remains in control mode) .
An exception is certain setup items, or flags, which can
activate special tasks, when set and confirmed .
To each setup parameter (or setup item) is assigned a three
characters (one letter followed by two digits) setup code
