6.1.1 Equipment Required
Ÿ Moore XTC Communicator (MXC) - refer to Section 2 of this User's Manual
Ÿ Laboratory grade digital multimeter (DMM); for calibrating the 4 to 20 mA output signal
Voltmeter Section ............. Accuracy +/-0.01% of reading
Resolution 1.0 mV
Input impedance 10 MΩ
Ammeter Section .............. Accuracy +/-0.1% of reading
Resolution +/-1 µA
Shunt resistance 10Ω or less
Ÿ 24 Vdc power supply; for bench calibration
Ÿ Resistor 250Ω +/-1%, carbon, 1/4 watt; for bench calibration
Ÿ Laboratory grade precision microammeter with a resolution of +/-0.001 µA; used to calibrate Current
Source.
Ÿ Precision adjustable millivolt source, range to 110 mV. Used to check and calibrate mV/thermocouple
inputs.
Ÿ Digital voltmeter to monitor the millivolt source with a resolution of +/- 0.001 mV for ranges up to 110
mV.
Ÿ Precision resistance decade box; 5-dial type with largest dial providing 100 ohm steps. Accuracy to
be +/-0.02 ohms. Used to simulate RTD/Ohm type input resistance.
Ÿ Thermocouple reference tables providing millivolts vs. temperature data. Use to check accuracy of
indicated temperature.
Ÿ RTD reference tables providing ohms vs. temperature data. Used to check accuracy of indicated
temperature.
6.1.2 Transmitter Analog Output (DAC) Calibration
Perform the steps in the appropriate Section according to the transmitter's normal operating mode: analog
operation, Section 6.1.2.1; digital operation, Section 6.1.2.2.
IMPORTANT
Calibration of the Digital-to-Analog Converter (DAC) is not normally
required and should be performed only after all other options have been
exhausted.
6.1.2.1 Transmitter Normally Configured for Analog Mode
If the transmitter is field mounted and conditions permit, calibration can be performed at the site as
described in steps 2 through 18. If a bench calibration is desired, perform steps 1 through 18.
1. Bench Calibration only: Disconnect the transmitter from the process by performing the steps in
Section 6.5.
