Page 2 of 14 Test Report No. R-5727N Retlif Testing Laboratories R Test Program Summary Applicant/Manufacturer: EnerTrac, Inc. 94 River Road, Suite 101 Hudson, NH 03051 Equipment under Test (EUT): The EUT is a transmitter operating in the Part 90 Industrial/Business Radio Pool and will be mounted to oil tanks. It will be used to wirelessly send tank level status information to a remote receiver. Model: Oil eSensor Part Number: 0005618 FCC ID Number: X94-0005618REVB00 Applicable Test Standards: FCC Parts 2 & 90.217 90.217 Exemption from The EUT will have an output power less than 120 mW and operate at frequencies listed in Part 90, Subpart C. The EUT is thereby subject only to the technical requirements of 90.217. Technical Standards Measurement Procedure: ANSI/TIA-603-C-2004 EUT Frequency Range Band: 450 MHz – 470 MHz EUT Channels: 464.725 MHz, 464.700 MHz, 464.650 MHz, 464.625 MHz, 464.600 MHz Power Output Rating: 74.75 mW (ERP) Modulation Type: AM Antenna Type: Integral Omni Directional (No Antenna Port) Input Power: 3.6 VDC via one (1) internal lithium thionyl chloride battery RF Exposure: The EUT will operate at a frequency less than 1.5 GHz with an ERP of less than 1.5 W and is therefore exempt from routine evaluation Temporary Hardware Modification: In order to enable continuous transmission during testing, a temporary hardware modification was required. A larger capacitor was installed then is typically used in production units. Support Equipment: No support equipment was utilized Page 3 of 14 Test Report No. R-5727N Retlif Testing Laboratories R Test Program Summary (continued) Measurements Required:  RF Power Output (2.1046/90.217)  Occupied Bandwidth (2.1049/90.217 (b)  Effective Radiated Power of Spurious Radiation (2.1053/90.217)  Frequency Stability (2.1055/90.217) RF Output Power (ERP) Measurement Procedure: In order to be considered exempt from the other technical requirements of Part 90 and subject only to the technical requirements of 90.217 the output power of the EUT must be less than 120 mW. The test sample was placed on an 80 cm high wooden test stand which was located 3 meters from the test antenna on an FCC listed test site. The effective radiated power of the fundamental frequency was measured using the substitution method specified in ANSI/TIA-603-C-2004. The maximum ERP of the fundamental frequency was measured to be 74.75 mW. See the attached test data. Effective Radiated Power of Spurious Radiation Measurement Procedure: The test sample was placed on an 80cm high wooden test stand which was located 3 meters from the test antenna on an FCC listed test site. The effective radiated power of each spurious emission was measured using the substitution method specified in ANSI/TIA-603-C-2004. The frequency range of the test was 30 MHz – 5 GHz. The limit for out of band spurious emissions is -30 dBc as specified in Part 90.217. No emissions were observed within 20 dB of the specified limit. See the attached test data. Page 4 of 14 Test Report No. R-5727N Retlif Testing Laboratories R Test Program Summary (continued) Frequency Stability/Occupied Bandwidth Measurement Procedure: Per 90.217(b), for equipment designed to operate with a 12.5 kHz channel bandwidth, the sum of the bandwidth occupied by the emitted signal plus the bandwidth required for frequency stability shall be adjusted so that any emission appearing on a frequency 25 kHz or more removed from the assigned frequency is attenuated at least 30 dB below the unmodulated carrier. The test sample was placed into a temperature chamber with a variable DC power source supplying power to the EUT. With the test sample operating at maximum output power the test sample’s fundamental output frequency was measured and recorded at 10 degree increments from -30 degrees C to +50 degrees C. At each 10 degree increment, frequency measurements were taken with the DC input voltage set to 3.6 VDC (nominal internal battery voltage) and 1.6 VDC (lowest voltage at which the EUT will transmit). At each 10 degree increment and DC input voltage referenced above, frequency measurements were also made at the upper and lower -30 dBc points in order to determine the maximum occupied bandwidth of the signal. The maximum occupied bandwidth at -30dBc was determined to be 0.488 kHz. See the attached test data.
