Meets radiated and conducted emission require ments for the Interference Causing Equipment Standard f or Digital Apparatus of Industry Canada (ICES-003). IEC801-2, 3, 4 and EN55011 covering ESD, RFI Immunity, EFT/Burst and Radiated Emissions respectively for the Commission of the European Communities (CE)
Resistance to X-Rays Tested for protection against a 160kV dose @ 5mA for 30 seconds (150mA-sec) @ 38 inches F.F.D. (about 100 times that of an airport x-ray machine). Tested for protection against Gamma Ray (equivalent to 0.137-1.38 mega volts) IR 192 - 28 curies @ 30 second exposure source to object distance 5”


<td >Negative Temperature Coefficient Thermistor. 10,000 ohms @ 25°C (77°F)

Internal Temperature Sensor
Accuracy ± 0.2°C, over the range of 0 to 70°C (±0.3°F over the range of 32 to 158°F)
Range -40 to 70°C (-40 to 158°F)
Resolution 0.03°C (0.05°F) at 25°C (77°F). Better than 0.07°C (0.12°F) between -25°C (-13°F) and 70°C (158°F). Better than 0.13°C (0.23°F) between -40°C (-40°F) and -25°C (-13°F)


Internal Humidity Sensor
Type Capacitive thin polymer film
Range 0 to 95% RH (non-condensing)
Acccuracy ± 3% RH from 10 to 90% RH (-20 to 40°C [-4 to 104°F])
Resolution Better than 0.04% RH between 25 and 60% RH @ 25°C (77°F)
Environmental Conditions Like all relative humidity sensors, when exposed to contaminants and/or extreme environmental conditions, accuracy degradation could result. For maximum long term stability, sensor should not be exposed or subjected to organic solvents, corrosive agents (strong acids, SO2, H2SO4, Cl2, HCl, H2S, etc.), and strong bases (compounds with PH greater than 7). Dust settling on the sensor surface will not affect sensor performance except possibly to decrease the speed of response.
