Page 3: Transmitter Setting From The Manufacturer
Instruction Manual for use of temperature and relative humidity transmitter T3413, T3417 Transmitter is designed for measurement of air temperature at °C or °F and relative humidity of air without aggressive ingredients. Measured temperature and relative humidity are recomputed to humidity expression: dew point temperature, absolute humidity, specific humidity, mixing ratio and specific enthalpy. - Page 4 1200m. The cable must be located at indoor rooms. Nominal cable impedance should be 100 Ω, loop resistance max. 240 Ω, cable capacity max. 65 pF/m. Outside diameter of the cable for T3413(D) and T3417(D) connection must be from 3 to 6.5 mm. Suitable cable is e.g. SYKFY 2x2x0.5 mm , where one wire pair serves for device powering and the other pair for communication link.

± 2.5 %RH from 5 to 95 %RH at 23 °C Accuracy: The value computed from air temperature and relative humidity: Absolute humidity Range: 0 to 400 g/m ±1,5g/m at air temperature T < 25°C (104 °F), for more details see Accuracy: graphs below IE-SNC-T3413(7)-10... - Page 11 This value depends on the barometric pressure. If device doesn’t support pressure measurement, then constant value stored inside device memory is used. Default value preset by manufacturer is 1013hPa and can be changed by user’s software. This maximum is reached under conditions about 70°C/100%RH or 80°C/70%RH IE-SNC-T3413(7)-10...
