Transmitter Calibration with the Fluke 750 Series Documenting Process Calibrator The precision sourcing and measurement capabilities of the rugged Fluke Documenting Process Calibrator DPC make it an ideal choice for the calibration of process instrumentation The following examples show how to address trans mitter calibrations quickly and effectively using the Fluke 753 or 754 Documenting Process Calibrators Rosemount 444 Figure 1 Connect a type K mini connector into the TC input of the DPC and connect to the thermocouple input of the transmitter Figure 1 It is necessary that you use the correct type of mini connec tor for this connection to the DPC Connect the center two ter minals of the DPC to the con nections on the transmitter where loop power is applied Figure 1 Note If you prefer to use house loop power rather than supplying loop power from the DPC connect these two leads in series with the loop supply to the transmitter Fluke DPC Application Note Once your connections are made starting from the DPC power up state or measure screen select the mA but ton to measure milliamps Figure 2 Source OFF 0 000 mA Scale Hange More Figure 2 4 Next depress the MEAS SOURCE button now you are in the source screen Since you want to source a thermocouple press TC RTD once Press ENTER to select TC Use the down
