The Service Menu is accessed from the index display by pressing button A to move to

meter then shows the Engineer Access screen:-
,
Pressing button A will then show the Pin code Access Screen.
The PIN code is 6 characters which are determined at the time of manufacture.
The PIN code is displayed with all characters represented as * with a cursor under the
first one. The characters are entered pressing button A until the desired character is
shown in that position. Pressing button B will move to the next character on the right. It is
possible to roll around back to the beginning if necessary to correct errors.
Holding button B for more than 3 seconds causes the meter to check the PIN code
against the entered one. If the PIN code is correct, access to the menus is granted.
If the PIN code is incorrect, an error message is displayed, followed by the default
display.
If more than 4 successive incorrect PIN codes are entered, the menu entry dialog will be
locked out for a period of one hour and a fraud event recorded in the Event Log.
Once the Service Menu has been selected, the first menu option is displayed. The option
is selected by pressing button A, the next option is displayed by pressing button B. The
default display will be shown after the last menu option or when the option has been
displayed for a period of time without a button being selected.
