This document provides instructions for obtaining meter readings from a Secure Handset and directly from Secure electricity and gas meters.
Secure Handset Description
The Secure Handset is a device designed to display electricity and gas meter readings, offering a convenient way for users to monitor their energy consumption. It features a monochrome display with a user-friendly interface, allowing navigation through various menus to access historical data and settings.
Function Description:
The primary function of the Secure Handset is to retrieve and display meter readings for both electricity and gas. It acts as a remote interface to the smart meters, providing real-time and historical consumption data. Users can switch between electricity and gas readings, view daily, weekly, or monthly consumption, and access other settings related to their energy usage.
Usage Features:
- Main Menu Navigation: The handset displays a main menu with options such as "Message," "History," "Tariff," "Account," and "Settings." To access meter readings, the user needs to press the "History" button.
- Switching Between Fuels: If the user has dual fuel meters (electricity and gas), the handset allows switching between "Electricity" and "Gas" readings. This is achieved by pressing a dedicated button, typically labeled "Electricity" or "Gas," which toggles the display between the two fuel types.
- Viewing Historical Data: Once in the "History" screen, the handset initially displays readings for the current "Hour." To view cumulative readings for a longer period, such as a month, the user needs to press the top right-hand button repeatedly until "Month" is displayed. This changes the "Period Total" to show the cumulative consumption for the selected period (e.g., "Cuml: XXXXX" for monthly cumulative).
- Display Elements: The display shows the current time (e.g., "15:38"), date (e.g., "23.11.14"), and various data points such as "Period Total" (e.g., "75.4 kWh" or "Cuml: XXXXX kWh"). It also includes a graphical representation of consumption over a period (e.g., "M T W T F S S M" for days of the week).
- Target Feature: The handset includes a "Target" feature, although its specific functionality is not detailed in the provided document. It likely allows users to set consumption targets and track their progress.
Technical Specifications (Inferred from images):
- Display: Monochrome LCD.
- Navigation: Button-based interface.
- Connectivity: Wirelessly communicates with smart meters (implied by "Handset" functionality).
- Power Source: Not specified, but typically battery-powered for portability.
Maintenance Features:
The document does not explicitly detail maintenance features for the handset. However, general maintenance would likely involve:
- Keeping the device clean and dry.
- Replacing batteries when indicated (if battery-powered).
- Ensuring the device is within range of the smart meters for proper communication.
Secure Electricity Meter Description
The Secure Electricity Meter is a smart meter designed to measure and record electricity consumption. It features a digital display and a keypad for direct interaction.
Function Description:
The primary function of the Secure Electricity Meter is to accurately measure and record electricity usage in kilowatt-hours (kWh). As a smart meter, it is capable of two-way communication, allowing for remote meter readings and potentially other smart grid functionalities. It also provides a direct interface for users to view their current meter reading.
Important Technical Specifications:
- Model: Secure Liberty 100 (Type Code MAX10Y).
- Type: 1P. 2W, 230V, CIB 50Hz (Single Phase, 2 Wire, 230 Volts, 50 Hertz).

- Temperature Range: -25°C to 55°C.
- Constant: 3200 Imp/kWh (3200 impulses per kilowatt-hour, indicating the meter's pulse output for energy measurement).
- Standards: EN50470-1, EN50470-3, UK 0120/SGS0100.
- Accuracy Class: CE M12 0120 (Class B accuracy, certified in 2012).
- Serial Number (Sr. No.): S0000358, XA133448.
- MAC ID: 88797E0000001FAA.
- IMEI No.: 359193032809709.
- Year of Manufacture: 2013.
- Property of: Secure Meters (UK) Ltd.
- Connectivity: WAN (Wide Area Network) and HAN (Home Area Network) capabilities, indicated by "WAN HAN" symbols.
Usage Features:
- Direct Meter Reading: The meter has a digital display that shows the meter reading (e.g., "XXXXX").
- Keypad Interaction: A keypad with numerical buttons (0-9) and function buttons (A, B) is present. To view the meter reading, the user needs to press the "9" button once.
- Status Indicators: LEDs or symbols for WAN and HAN connectivity are visible, indicating the meter's communication status.
Maintenance Features:
- The meter is designed for long-term, low-maintenance operation once installed.
- It is sealed (indicated by "Property of Secure Meters (UK) Ltd."), implying that internal components are not user-serviceable.
- Regular maintenance would typically involve remote monitoring and occasional on-site checks by utility providers.
Secure Gas Meter Description
The Secure Gas Meter is a smart meter designed to measure and record gas consumption. Similar to the electricity meter, it features a digital display and a keypad for direct user interaction.
Function Description:
The primary function of the Secure Gas Meter is to accurately measure and record gas usage, typically in cubic meters (m³). As a smart meter, it facilitates remote meter readings and integrates into a smart energy system. It also provides a direct interface for users to view their current gas meter reading.
Important Technical Specifications:
- Model: Liberty EG4v 10.
- Type Code: G01163.
- Maximum Flow Rate (Qmax): 6 m³/h.
- Minimum Flow Rate (Qmin): 0.04 m³/h.
- Maximum Pressure (Pmax): 0.2 bar.
- Temperature Range: -10°C to +55°C.
- Standards: BS EN 16314-2011, BS EN 1350 1999/A1.
- Accuracy Class: CE M12 (Certified in 2012).
- Explosion Protection: Ex nAll T6 Ex (Indicates suitability for use in potentially explosive atmospheres, specifically Zone 2, with a temperature class T6).
- Serial Number (Sr. No.): XA132273.
