1. Introduction To The FOCUS The FOCUS meter was designed to be a low-cost, solid-state, kWh-only meter as an alternative metering and AMR platform to the induction meter. The meter is based on reliable, field proven digital multiplication measurement technique. The meter platform will measure energy accurately over varying environmental conditions. It is designed to be stable over its long expected life. A diagram of basic operation is noted below.
Figure 3 - Meter Assembly Exploded View The Focus meter is composed of three basic sub-assemblies: The baseplate assembly, the electronics housing assembly and the meter cover. The electronics housing assembly snaps onto the baseplate and creates a weatherproof seal when the cover is installed. The standard cover includes an emboss to align an optical probe for register configuration purposes.
Electronic Housing Assembly Figure 5 - Electronics Housing Assembly Exploded View The Electronics Housing contains the measurement board and any optional electronics assemblies such as option boards or communication devices. It also contains the liquid crystal display (LCD) on which meter readings and other pertinent data can be displayed. The Electronics Housing assembly snaps onto the baseplate and can be removed and reinstalled many times without damage to the meter.
2. The FOCUS Meter Family The FOCUS provides more than just reliability and accurate billing data. The FOCUS is designed to be a building block for a complete metering system. Each FOCUS has built-in compatibility for a variety of AMR packages. Any of these can be factory installed. Some can be added to the meter dependent upon the meter vintage and respective AMR technology. Register Types The Focus kWh is an active energy “kWh-only” meter.
3. Meter Assembly Removal of the Electronics Housing from the Baseplate In rare instances, it may be necessary to access the inner electronics of the Focus meter. To remove the Electronics Housing from the baseplate, set meter on a solid surface and place hands around the bottom of the gray housing where it meets with the baseplate.
Figure 8 – Unused T-Seals Figure 9 – Formed T-Seal After Installation Figure 10 – T-Seal Installed Each T-seal is installed by fully inserting it through the cover and through the baseplate assembly. Bend the T-seal tab to prevent extraction. Next, bend the T-seal over so that it resides within the baseplate assembly pocket. Finally, bend the top of the T-seal over so that it is flush against the cover.

4.1.3. Socket base 1). Compare wiring with diagrams of Section 3.2 to make sure the meter is wired properly. 2). Plug meter terminal blades into socket to make a connection with the terminal jaws. 3). Apply load. 4). Check to make sure that the LCD operates and sequences through the display items which were programmed into the meter. 4.1.4. K-Base 1). Compare the wiring with diagrams of Section 3.2 to made sure the meter is wired properly. Install bypasses (if change-out). 2).
5. Overview of Electronic Hardware 5.1.1. LCD Display Figure 16 – Liquid Crystal Display The kWh FOCUS LCD shows the digital power indicator, nominal service voltage and various selectable metrics. 5.1.2. Display Scroll Sequence: The display scroll sequence is programmable at the factory or by the user with Focus Configuration Tool. The scroll sequence can consist of up to 16 individual displays.
When internal meter errors occur, error codes will be added to the end of the scroll sequence. The segment check display does not affect the DPI. This permits a user to use the DPI for timing when a segment check is being displayed during a scroll sequence. A two character programmable alphanumeric label can be associated with each display. This twocharacter field is used to identify the value displayed. It can be left blank if desired. 5.1.3.
Diagnostics/Error Codes 5.1.6. Meter Errors The following table contains the meter errors available for display in the diagnostic status word.
6. Configuring the Meter 6.1.1. Configuration Port The ability to configure the meter is provided through a secure meter configuration port. A cover mounted optical configuration port accommodates meter configuration by the user. The configuration port is designed to be used in a meter shop environment, (room temperature/ambient lighting conditions). The configuration port interface supports a read/write security function.
7. Meter Calibration 7.1.1. Calibration LED The Focus kWh has an infrared light emitting diode (LED) that emits energy pulses. The calibration LED is deactivated 24 hours after the meter powers up. Once reactivated (recycle power), the calibration LED remains active for 24 hours. The calibration LED is accessible from the front of the meter cover. The user can fix an LED pickup device to the front of the meter.
7.1.2. Factory Calibration The meter is calibrated at the factory as part of the manufacturing process. Calibration constants are stored in nonvolatile memory. These constants are not alterable once programmed except through another calibration cycle at the factory. Sufficient security features are provided to prevent the user from altering the calibration constants stored within the meter. 7.1.3. Customer Calibration Adjustment Focus kWh calibration is adjustable.
9. Pulse Outputs The Focus kWh offers three internal solid-state pulse initiator outputs. Refer to Landis+Gyr Focus kWh Pulse Outputs Application Note (Doc. No. 04061-0) for detailed description of Pulse Outputs Functionality. 9.1.1. Relay #1 Output (KYZ only) KYZ is available as an option to the FOCUS meter. The option board can be assembled in the meter at the time of order or can be meter shop retrofitted. kWh FOCUS Options One Relay: Programmable for KYZ.
In the kWh FOCUS, pulse initiator signals are provided by Relay 1. The KYZ output value can be any one of the three choices listed in Table 10 below: Metric Choices Select any one 1). +kWh 2). –kWh 3).
9.1.2. Communications (Pulse Initiator 1 and 2) Focus kWh provides two scalable TTL-level pulse outputs for interfacing with pulse accumulating AMR modules. Each output is user configurable to function in one of two operating modes: 1) Quadrature Pulse and 2) Differential +kWh Pulse. These are used only for configuration of factory installed or field retrofitted AMR modules (under glass).
