The A100C meter is housed in an extremely compact case. To further enhance security, the main meter cover is permanently secured to the base during the manufacturing process. The extended cover makes for much easier fitting from improved accessibility.

The A100C has the option of IrDA or optical IEC 62056-21 (formerly IEC 61107) communications. Both methods of communication allow the meter registers and security data to be read electronically from a laptop or hand-held device, greatly reducing the possibility of manual meter reading errors. The IrDA data can be hardwired through the auxiliary terminals, allowing AMI modules to be added that can be used to retrieve the absolute register reads and security data.

The liquid crystal display has large (9.8mm), high contrast characters that can be viewed from a wide angle. Chevrons and multilingual legends on the nameplate identify the values being displayed. The energy registers can be configured for the required number of digits and for the position of the decimal point. 

The A100C offers high security and detects many of the most commonly used tamper techniques. Security features of the meter include reverse run energy total and count; power fail and elapsed time count; hours in anti-creep; hours in Rate 1, Rate 2 and hours since last power up time. These are stored as security data and can be included as part of the display sequence and read via the optical communications ports.

The A100C can be a simple import meter or import/export for domestic or small scale generation sites. The meter offers one or two rate operation. The rate select for the two rate meter is switch to neutral.

Meters can be supplied to meet accuracy Class 1 or Class 2 requirements. They are approved to EN 62053-21:2003, have an ingress protection of IP53 to IEC 60529:1989 and comply with EMC standard EN 50081-1 1992. 

The A100C conforms to:

• The general requirements and particular requirements of EN 50470 Parts 1 & 3, and complies with Class M2 Mechanical environment and Class E2 Electromagnetic Environment.
• IEC 62053 - 21  kWh, Class 1 or 2 Static
• BS 7856 Dimensional Requirements (BS meter)
• DIN 43857  Dimensional Requirements (DIN meter)
• EN 50470 - 3  kWh Class A or B (DIN IrDA meter only)
• EC Directive 2004/22/EC (MID) Class A or B (DIN IrDA meter only)
• The degree of ingress protection is to IP53, IEC 60529:1989

Meters are marked with the European CE Mark, in accordance with the Marking Directive 93/68/EEC to indicate compliance with the requirements of the EMC Directive 89/336/EEC.

Variables of the A100C are approved by the Office of Gas and Electricity Markets (OFGEM) in compliance with European and British metering legislation (Approval Number 984). These are identified in the model code. Other variants will be approved by International Authorities in line with local requirements.
