Aclara Technologies LLC Former HEXAGRAM Inc. 30400 Solon Road . Solon, OH 44139 440-528-7200 03/28/2012 LLB11005S RF Exposure calculations Based on FCC 1.1307 & 2.1091, FCC OET Bulletin 65. (1) Categorically Exclusion from RF exposure Evaluation: According to FCC regulations, RF exposure evaluation is Categorically Excluded if transmitter’s operation frequency is less than 1.5 GHz and ERP is less than 1.5 watt. (2) Absolute Maximum specifications of LLB11005S transmitter • Operational frequency band 450 MHz to 470 MHz. • The LLB11005S transmitter is measured for Max RF Power = 0.224 W. • Absolute Maximum transmission time (duration) for any Hexagram transmitters does not exceed 100 mS (0.10second). • Transmission period – Absolute maximum is 4 transmissions per hour. • All Hexagram Transmitters utilize FSK modulation. (3) Average RF Power Calculation: FCC regulations on permissible RF exposure are not based on peak envelope power (PEP), but on average power (P_ave) over a 30-minute time period for uncontrolled environments. As mentioned in (2), during any 30 minute Hexagram MTU can transmit only two times. Duration = 0.10 second. With maximum RF radiation equal to 0.224 W, the Average RF Power over 30 minutes is: P_ave (worst case) at 30 minute = 0.224W*30* [0.10sec/((30*60)sec)] = 0.224*30* 0.000055 = 0.36mW (4) Maximum Radiated Power Density prediction (S): To predict power density (S) at distance R=20 cm from transmitter with P_ave = 0.00007W, next formula is used: S = P_ave/(4*(PI)*R^2) For the worst of the worst worst-case prediction of power density at or near a transmitter surface let’s use: S = P_ave/((PI)*R^2) = 0.36 mW/(4*3.14*20cm*20cm) = 71uW/cm^2. This is the worst case of the near field power density of LLB11005S transmitter. (5) Maximum Permissible Exposure (MPE): AS FCC require, the maximum permissible exposure for general public in “uncontrolled situation” at 20 cm is: MPE = 460MHz/1500 = 1.228 mW/cm^2. By comparing results in (4) and (5), S=71uW/cm^2 < MPE=1.228 mW/cm^2. We see that LLB11005S fully complies with RF safety at a distance of 20 cm.

James R. Pollock 30400 Solon Road Solon Ohio 44139 (440)528-7200 ENGINEERING TEST REPORT RADIO-FREQUENCY EMISSIONS TEST REPORT FOR HIGH READ-RATE GAS METER TRANSMITTING UNIT OCCUPIED BANDWIDTH TRANSIENT BEHAVIOR Model 2011-005, Rev. C FCC ID: LLB11005S March 28, 2012 Report Prepared by Agency Certification Control Technician ACLARA TECHNOLOGIES LLC 2 TEST REPORT INTRODUCTION The Aclara Model 2011-005 transceiver is a “Meter Transmitting Unit” (MTU) designed to provide remote meter reading capability for a gas meter. The transceiver is self-powered and mounts directly on a gas meter. On board batteries provide power. The transmitter provides a very short, intermittent radio frequency transmission to send a remote reading of the meter to a data collector unit. A microprocessor provides timing, control and data processing functions. The internal antenna is inaccessible to the user and no external antenna is provided. Two identical units were used as a test subjects for this report. The unit used for each test is identified under the test procedure. This report presents the data obtained in support of an application for Certification under Part 90 of the FCC rules. MEASUREMENTS PERFORMED Occupied Bandwdth Page 3 Transient Behavior Page 5 3 OCCUPIED BANDWIDTH The emissions close to the center of the specified channel are limited by the emissions masks described in 90.210. For the frequency range of the 2011-005 transmitter, Mask D is specified. From the center frequency of the band ±5.625 kHz, 0 dB of attenuation is required. From 5.625 kHz to 12.5 kHz from the center frequency, attenuation must be at least 7.27(f d – 2.88 kHz) dB, where f d is the displacement frequency from the center of the band in kHz. At more than 12.5 kHz from the band center, the attenuation must be 70 dB or 50 + 10 log(P), whichever is less. The maximum dipole equivalent power was determined to be 23.5 dBm or 0.224 W and 50 + 10 log(0.224) equals 43.5 dB. The mask measurement was a conducted measurement, and as seen in Fig. 1, the measured output power was 25.1 dBm so the maximum allowed is shown on the plot as -20 dBm or 45.1 dB below the measured level. Both modulated and unmodulated transmissions were stored on the spectrum analyzer display. The plot of Fig. 1 shows both signals with Mask D superimposed on the plot. The plot indicates that the modulated emission does comply with the requirement for occupied bandwidth as found in 90.210. For purposes of this test, the modulated signal was PN9 modulated at the specified 7200 bits per second data rate.

C SN: 80003090 5 TRANSIENT STABILITY The transient stability measurements indicate the variation in tuned frequency during the brief interval of time during the start of the transmission and at the end of the transmission. The Model 2011-005 transmitter was tested for transient frequency behavior using the test method of TIA/EIA-603-C. A block diagram of the test setup is seen in Fig. 2. A Hexagram model 9975G-WB receiver was used. The storage oscilloscope was triggered by the output of the RSSI output of the receiver. Appropriate delay was provided by the digital delay circuitry of the oscilloscope. The 1 kHz test signal was provided by the Marconi signal generator. The generator’s output control was used to insure that the test signal was at least 50 dB below the received signal level from the 2011-005.

The transceiver is mounted within the meter enclosure. The transmitter provides a very short intermittent RF transmission to provide a remote reading of the meter. A microprocessor provides timing, control and data processing functions. The built in antenna is inaccessible to the user and no provision is made for an external antenna. The receiver can be used to request a meter reading or other options available in the system. Power Output: The EUT operates in the frequency range of (450 - 470) MHz. The first step in the measurement process was to measure the field strength of the fundamental frequency at the lowest, highest and middle operating frequency. These measurements are made in both the vertical and horizontal polarity. The maximum field strength is reported by raising and lowering the measuring antenna height between (1-4) meters and by rotating the EUT (360) degrees. The measurement distance is (3) meters. The field strength measurements continue as described above for up to the tenth harmonic of each fundamental frequency. Once the field strength of each signal is recorded, the EUT is replaced with a substitution antenna and signal generator. The substitution antenna is placed at the same height as the EUT had been. The combination of antenna and signal generator is then adjusted to reproduce the recorded field strength at each frequency. The ERP is then calculated by the following: ERP = PG - CL + ANT ERP = Effective Radiated Power (dBm) PG = Signal Generator Output (dBm) CL = Cable loss (dB) ANT = antenna gain (dBd) dBd = (antenna gain dBi) - (2.2 dB) The measurements were made using the standard ANSI/TIA-603-C-2004. Occupied Bandwidth: The occupied bandwidth was measured with the EUT set to low, medium and high transmit frequencies. The emissions mask used was that specified in Part 90.210 (d). Radiated Spurious Emissions: The radiated spurious emissions measurements were measured with the EUT set to low, medium and high transmit frequencies. Based upon the low output power of this device, all spurious and harmonic signals are limited to (-20) dBm. This is based upon the calculation stated in 90.210(d)(3). The field strength of the spurious emissions were measured in the same manner as the power output measurements and then the substitution method was used to establish the power level expressed in dBm. Frequency Stability vs. Supply Voltage: One of the internal batteries was disconnected and replaced with an external variable power supply. The frequency was measured at the normal battery voltage of (7.20) VDC and again with the external power supply adjusted to an (85%) level or (6.12) volts. This was repeated with the external DC voltage adjusted to (8.28) VDC. The maximum allowed deviation is (2.5) ppm or (1,150) Hz at (460) MHz. Aclara Technologies LLC FCC ID: LLB11005S age 3 of 11 Frequency Stability vs. Temperature: The fundamental frequency was measured at an ambient temperature of (20) degrees C and recorded. The transmitter was then placed in a container along with a small section of dry ice and the environment was adjusted until a low temperature of (-30) degrees C was achieved. The transmitter was allowed to stabilize for (30) minutes at this temperature and then the frequency was again measured with a spectrum analyzer. The environment was allowed to warm to (-20) degrees C and the measurement process was repeated. The environment was moved to a maximum temperature of (+80) degrees C in (10) degree increments, allowed to stabilize for (30) minutes and the frequency was re-measured.
