Page 4: General Description
General description The transmitters T3110 are designed for measurement of ambient temperature and relative humidity of air without aggressive substances. Measured values are converted to other humidity interpretation: dew point temperature, absolute humidity, specific humidity, mixing ratio, specific enthalpy. Measured and computed values are displayed on a two-line LCD display. -

Page 7: Device Installation
“Typical application wiring”. For device connection it is recommended to use a shielded cable with a maximum length of 1200m. External diameter of the cable for T3110 and T3110Ex connection is 4 to 8 mm. For T3311L connection use cable with respect to female connector parameters (do not connect shielding at connector side). -
Page 8: Info Mode
During info mode no measurement and no output current generation proceed. The transmitter stays at info mode 15 s and then automatically goes back to measuring cycle. The verifying of settings of the T3110Ex transmitter is permitted only in non-hazardous area. IE-SNC-T3110-09... -
