NASA Tests Overview

Certificate of Conformance - Standard
The UL101-R and UT2000 models are in compliance with the contract, drawings, standards, specifications and any other applicable documentation, which categorizes the purchased goods as the "Standard Model" equipment. All process certifications and/or governing reports, and (chemical & physical test reports) if applicable, are on file at the CTRL home office, and are available for (review by our Customers, End Users, and/or by the appropriate Government Agencies, specified as such:
CTRL UL101 Receiver Unit - Model UL101-R (S/N: RA01000 and higher)
Universal Trnsmitter Unit - Model UT2000 (S/N: TA01000 and higher)

Certificate of Conformance - Intrinsically Safe
The UL101-RE and UT2000E models are in compliance with the contract, drawings, standards, specifications and any other applicable documentation, which categorizes the purchased goods as "Intrinsically Safe". All process certifications and/or governing reports (specifically Test Report No: 150479 issued on March 28, 2001), and (chemical & physical test reports) if applicable, are on file at the CTRL home office, and are available for review by our Customers, End Users, and/or by the appropriate Givernment Agencies, specified as such. The models meet or exceed the following requirements of ANSI/UL 913-88, for DIVISION 1, CLASS I, Groups A, B, C, and D, CLASS II, Groups E, F, G and CLASS III. It also complies with DIVISION 2, CLASS I, Groups A, B, C, and D, CLASS II, Groups F, G and CLASS III.
CTRL UL101 Receiver Unit - Model UL101-R (S/N: RA01000 and higher)
Universal Trnsmitter Unit - Model UT2000 (S/N: TA01000 and higher)

EU Declaration of Conformity
The CTRL UL101 and UT2000 for serial numbers RA03700 and TA03700 respectively (including groups 30000, 70000, and 90000 that reference all models released subsequently to the EU Declaration) comply with the following EU Directives:
89/336/EEC Electromagnetic Compatibility Directive, amended by 92/31/EEC & 93/68/EEC
73/23/EEC Low Voltage Equipment Directive, amended by 93/68/EEC
The mentioned products meet the following standards:
EN 55011 Emissions Test
EN 50082-1 Immunity Test
EN 61010-1 Safety Requirements
Any technical documentation needed to demonstrate that the product meets the requirements of the Low Voltage Directive are available for inspection by the relevant enforcement authorities. The CE mark was first applied in January 2001.

PowerBeam 300 for Remote Detection of Corona Discharge
The PowerBeam 300 is a designed attachment for the CTRL UL101 receiver to detect corona discharge from cracked insulators and high tension lines at safe distances. The functional aspects of the PB300 have been tested and certified by independant third party research institutes such as The Central Power Research Institute (CPRI) in India.

Standards for Headset
The CTRL Headset, manufactured by David Clark specifically for the UL101 Receiver, meets and exceeds ANSI specificatioms and OSHA standards.

NASA Tests Overview
Venting Analysis - When depressurized and/or repressurized, the UL101 and UT2000 have a maximum pressure differential between 0.06 psi and 0.14 psi.
Rear Cap Analysis - The rear cap of the UL101 Receiver and UT2000 Transmitter will not separate when 2.0 lbs force is applied. The maximum load on the rear cap due to venting is 0.163 lbs force.
Vibration Test - Random vibrations did not effect the operation of the UL101 and UT2000 in the frequency range 20 to 2000 Hz at the level 6.06 G's RMS for a duration of 1.00 seconds per axis.
Electromagnetic Interference (EMI) Quality Test - The UL101 Receiver was tested and passed at several levels in the range 0.014 MHz to 15,500 MHz peak.
Noise Limits - The UT2000 tested for emitted noise relative to requirements for ultrasonic noise. The overall sound pressure level was measured for the frequency range 10 Hz to 70 kHz at 60 cm and found to be 99 dB re 20 micro PA. At specific frequencies measurable by NASA, the overall sound pressure was measured between 36 and 44 dB re 20 micro PA.
