4 PIN Numbers

We have borrowed the term “PIN” from the banking industry. It stands

for “Personal Identification Number”.

The MR500 uses PINs, or as we frequently call them “PIN Numbers”,

extensively to control functions that are important to the security of the

information in the meter and in controlling its use.

The use of the specific PINs is explained in later sections. However,

this section contains an overview.

4.1 How are PIN Numbers Formed?

• A PIN number for an MR500 may contain only the digits

1,2,3,4 or 5. This makes a PIN number easy to enter into

the front panel of the meter by using the five buttons.

• PIN numbers may be either 3 or 6 digits long.

4.2 The MR500’s Built-In PIN Numbers

The MR500 has three PIN numbers, which are programmed into it

when it is first manufactured. These cannot be changed. These are

all six-digit numbers, which provide 15,625 possible combinations.

A record of these numbers is provided with your new MR500.

The numbers are:

4.2.1 The “Disable” PIN Number

This PIN allows you to control the use of your MR500 by only

allowing it to work for a pre-set period of time before it is disabled.

See section 5.4.3 for details.

❢ The “Disable Feature” is dependent on the settings in your

Tariff. It may not, therefore, be available on your MR500.
