  • Page 2: Device Setting From The Manufacturer

    Instruction manual for use of T3113, T3117 transmitters Transmitter is designed for measurement of air temperature at °C or °F and relative humidity without aggressive ingredients with computing one of the following values: dew point temperature, absolute humidity, specific humidity, mixing ratio and specific enthalpy. Measuring temperature and relative humidity sensors are non-removable instrument parts.

    LCD Info mode Several settings of installed transmitter is possible to verify without a use of the computer. It is necessary to connect at least power of current loop I1. Unscrew the transmitter lid and shortly press button between display and interconnection terminals by means of a tool (e.g.

  • Page 6: Technical Parameters

    Technical parameters: Accuracy data shown are for value displayed on LCD display. For value on analog output is valid too, if selected output range is set inside measuring range. Analog outputs: Two galvanic isolated current loops with range from 4 to 20 mA Current output in case of error: <3.8 mA or >24 mA Power: 9 to 30 V dc, maximum ripple 0.5 % Measuring parameters:...
