10. See AWSTech Note 203A For best measurement accuracy with thermocouple sensors it is advisable to shield the top terminals by placing the transmitter into a housing or enclosure such as the model XP FN XP FG XP HEAD or WP HEAD In addition sufficient time should be allowed for the housing and the transmitter to reach equilibrium temperature in a given operating environment before best accuracy is reached For best accuracy with any sensor or in the millivolt mode it is advisable to allow the transmitter to operate with the desired fixed input signal for a period of 30 seconds before the reading is taken The transmitter periodically measures certain internal references These internal measurements and the external signal undergo digital averaging and the full accuracy of the instrument is only achieved after several readings have been averaged When using an RTD sensor a four wire connection is generally recommended With a three wire RTD the Al 1500 makes two separate measurements before calculating the temperature whereas only a single measurement is required when using a four wire RTD Conceptually a better accuracy is possible using a single measurement as compared with calculating the difference of two separate measurements See AWSTech Note 209 for further information on the measurement accuracy improvement that is possible with true four wire RTD measurements AWS Al 1500 User Manual Rev 4 Page 49 8 0 ACCESSORIES 8 INFORMATIO

This transmitter is simple to set up and operates much like high performance analog transmitters The Al 1500 also has numerous advanced features that are achieved through the use of digital signal processing and micro controller technologies Typical of these features are the precision linearization the independent zero and full scale settings digital filtering etc Other advanced features such as the automatic self diagnostics and the exceptional stability are transparent to the user and are continuously active The Al 1500 transmitter can also accept one of two optional plug in displays The DK 1 is an inexpensive single line display that is intended to give a low cost local indication of the measured temperature The DK 2 two line display will give a local indication and functions as a very easy to use set up tool Both displays facilitate local configuration and ranging of the transmitter This manual is divided into several sections After a brief INTRODUCTION the section on UNPACKING AND INSTALLATION contains much useful information for the first time installer The section called INA HURRY helps get the system operating provided the sensor and transmitter were purchased at the same time and thus most of the set up was completed at the factory The next two sections explain the method of CONFIGURATION using either display The following sections explain configuration using HART Communications and the Fisher Rosemount HC275 Hand Held Commu
