CALIBRATION AND MAINTENANCE

12. Read the ammeter. If the output is within limits, press QUIT (F3) and proceed to step 13.

If calibration is still required, repeat step 10 as many times as necessary until the output is within limits, then press QUIT and proceed to step 13.

15.If the output is within limits, press QUIT (F3) and exit the calibration mode. Calibration is now complete; go to step 18.

If calibration is required, perform steps 16 and 17.

16.Respond to the prompt. Key in the current indicated by the ammeter and press ENTER (F4).

17.Read the ammeter. If output is within limits, press QUIT (F3) to exit the calibration mode.

If calibration is still required, repeat step 16 as many times as necessary until the output is within limits, then press QUIT (F3) to exit the calibration mode.

18.When calibration is completed, disconnect test equipment, reconnect transmitter as necessary. If transmitter is to operate in the digital mode, configure the short address to a number from 1 to 15 before disconnecting test equipment.

6.1.2.2 Transmitter Normally Configured for Digital Mode

When a transmitter is configured to operate in the digital mode, its analog output is parked at 4 mA. Although the analog output current function is not used when a transmitter is operating in the digital mode, it can cause communications interference on the Multi-Drop Network or an excessive current load. To check the analog output of a transmitter normally configured for digital mode, perform the steps in the preceding section.
