2 The transmitteris available in three standard ranges, or can beset for any range between -30 to 250 F (-34 to121 C) with a minimum span of 40 F (22 C).To adjust the T81U, set the DIP switches tomatch the desired range and use the zero andspan pots to fine tune. (A high accuracy digitalohm meter and decade box are required.)The XTD display option is a 3-1/2 digit LCD indi-cating the temperature range of the is factory calibrated to the TRANSMITTER Dip switch RANGEABLE Loop calibration test signal Low cost Snap-track mounting Loop power LED indication 1/2" LCD digital display, 3-1/2 digitsSensor input100 platinumTCR / / CConfigurationTwo-wire, loop-poweredRangeability limits T91U-30 to 250 F (-34 to 121 C)Min span of 40 F (22 C)Output4-20 mADisplay option (XTD)3-1/2 digit LCDO utput limit25 mA (sensor leads open)
