1. INTRODUCTION
1.1. General
This document is intended to provide detailed information required by an AMR
Meter Shop for the integration of AT RAMAR’s 900 series Electric Meter (EM)
TransPondIT Meter Interface Unit (MIU) product for single phase domestic
electricity meters in the US.
1.2. Scope
This document describes the 900 series EM TransPondIT MIU and provides the
necessary level of detail to enable the meter shop to install, test and deliver the
product ready for use by the customer.

2. PRODUCT DESCRIPTION
TransPondIT allows the utility to receive data from its meters remotely. The
TransPondIT collects data from the meter and transmits it to a data collection device,
which may be mobile or fixed. In addition, the TransPondIT is capable of detecting
reverse rotation and will transmit an alarm indication if there is doubt about the
validity of the reading. The TransPondIT can be read by the following RAMAR
products: HandTrackIT, FastTrackIT, or CellTrackIT with no change to the
TransPondIT.
The TransPondIT can be fitted or retro-fitted in minutes to the meter.
Only qualified and properly trained personnel should attempt the installation of the
EM MIU.
2.1. Ease of Installation
EM MIU units will be installed in two different settings; either with new meters at the
meter manufacturer’s plant or in approved meter shops that rework and calibrate
existing meters. It is a design criteria that the MIU be capable of being mounted in
a meter at point of meter calibration without additional tests other than ConFigIT to
confirm PSU connection and to load mechanical register data into electronic
register.
Mounting of the MIU in the meter takes similar time to that of mounting the lower
faceplate plus some time for connection of the power wires.
Mounting of the EM MIU within the electricity meter is simple with minimal operator
training required assuring proper installation and configuration settings by meter
shop employees or field personnel. Field personnel perform configuration of
account numbers at the end-user’s site with the EM ConFigIT device.
Clearing of tamper register in field is performed using ConFigIT.
Caution:
Changes or modifications not expressly approved by Advanced Technology
RAMAR Ltd could void the user’s authority to operate the equipment.

adaptor hardware.
The product is fitted in the location of the meter lower faceplate, utilising the existing
mounting stand-offs.
The MIU is enclosed in a plastic enclosure to provide protection in handling and
against direct sunlight.
Torque specifications will be provided for attachment fixings to ensure a reliable
installation.
The design avoids any requirement for alignment of pickup at time of installation.
No meter calibration points are obscured.

5.2. Power Supply
The unit takes mains power from the supply side of the meter.
No batteries are required.
The input voltage range over which the product must be able to read disk and send
transmissions is 100 – 260Vac.
Protection is provided so that the unit will survive the overvoltages and voltage
surges defined in ANSI C12.1.
There is no loss of configuration or meter reading data after power surge, brownout
or interrupt.
Power-line noise as defined in ANSI C12.1 does not adversely affect the unit.
The unit is appropriately protected to prevent the possibility of fire damage to a
residence.
Any hazardous voltage points have been protected to avoid accidental contact
during manufacture, service or calibration of the meter.
The average power consumption of the unit shall be less than 1.0W.
5.3. Measurement Technique
5.3.1. Mechanism
Electricity usage is measured by detecting rotation of the Ferraris disc. The
detection mechanism is frictionless and does not alter the balance of the disc.
The mechanism will restart regardless of disc position.
The detection mechanism will operate in ambient light levels of up to 100,000lux.
Reverse rotation is detected and causes the register to be decremented so that the
electronic register will match the mechanical register.
For meters where there is no suitable mark provided, the kit provided by the meter
shop shall include a mechanism for providing a black mark on disc that will not peel
off. The specifications of this mark are included in this document.
5.3.2. Accuracy
The electronic register is to reflect disc rotations to accuracy of better than 0.05%.
5.3.3. Tamper detection
The value in a tamper register shall be indicated in the following circumstances:
• if the circuit detects an internal fault
• if the sensor is disabled or
• if the rotation of the Ferraris disc is reversed (the design is to incorporate a
separate register to record reverse rotation).
Clearing of the tamper events is to be performed on site using ConFigIT.
5.4. Radio
Operational Range
The operational range is at least 300m in open field to a production HandTrackIT
held at height of 1.5m.
5.4.1. Transmit Carrier Frequency
The nominal transmission frequency shall be 919.8976MHz.
5.4.2. Antenna
The antenna is integral to the TransPondIT located within the glass case of the
electricity meter and does not hinder the installation of the product or obscure the
manually read dials, calibration screws or face-plate.
5.4.3. Transmission Interval
The transmit interval is configurable from 5 seconds to 10 hours.
