NOTE: For model TT190, the Zero and Span millivolt values are printed on the transmitter's label.
For model TT230, refer to a mV vs. T chart for the desired element type.
5. Connect a thermocouple simulator with cold junction compensation to the input of the transmitter.
6. Set thermocouple simulator to simulate the 4 mA temperature. For the given example, the
simulator should be set to -50 C.
7. Adjust ZERO potentiometer on the transmitter until the meter reads 4 mA.
8. Set thermocouple simulator to simulate the 20 mA temperature. For the given example, the
simulator should be set to 200 C.
9. Adjust SPAN potentiometer on the transmitter until the meter reads 20 mA.
10. For model TT230, repeat steps 6 - 9 until no further adjustment is necessary. Model TT190 has
non-interacting Zero and Span adjustments; therefore, steps 5 - 8 should not have to be
repeated. However, it is recommended that step 5 be repeated to check that meter still reads 4
mA to ensure proper calibration.
