The RTD can be simulated by decade resistor substitution box set to the appropriate values for the desired calibration. A table identifying the RTD temperature response is available upon request. 2) Identify transmitter temperature range by referencing the dash number and the DIP switch setting of the particular unit. Refer to the table on the next page. 3) Connect the device under test and the required test equipment as outlined on the attached wiring diagram. 4) Set the RTD simulator for the calibration range minimum temperature and adjust the Z(ero) potentiometer to obtain the minimum output of 4.000 mA. 5) Set the RTD simulator for the calibration range maximum temperature and adjust the S(pan) potentiometer to obtain the maximum output of 20.000 mA. 6) Repeat steps 4) and 5) until the device under test reads true without further adjustments.
