4.1.4. Constant Current Source Mode Procedure

1. Refer to Figure 17 for test connections. Verify the integrity of electrical components in the output
current loop.
2. Establish communication with the transmitter. For these procedures, the values of components in
the current loop are not critical if they support reliable communication between the transmitter
and the MC Toolkit.
3. On the MC Toolkit, display the Output Calibration box.
4. In the Output Calibration box, select the Loop Test button; the LOOP TEST box will be
displayed.
5. Select the desired constant-level Output: 0 %, 100 %, or Other (any between 0 % - 100 %).
6. Select the Set button. A box will be displayed asking Are you sure you want to place the
transmitter in output mode?
With the transmitter in Analog mode, you can observe the output on an
externally-connected meter or on a local meter.
7. Select the Yes button. Observe the output current at the percentage you selected in Step 5.
8. To view the monitor display, navigate back from the LOOP TEST display, and select the
MONITOR display. A Confirm popup will be displayed.
9. Select Yes to continue. This concludes the Startup procedure.
