Section 4 MC-III™ EXP Flow Analyzer
Output screen. In applications where short bursts of high ow rates are common (separators, tank loading,
dump cycles, etc.), the displayed ow rate can exceed the maximum ow rate for short periods without
compromising the accuracy of the total represented by the pulse output.

Pulse Output Testing
The MC-III software allows users to test the pulse output by writing a value to the pulse accumulator. Such
tests can aid in troubleshooting problems with hardware compatibility, threshold settings, and pulse duration
settings.
To use the test mode, press the “Test Pulse Output” button at the bottom of the Pulse Output screen. The test
page will appear (Figure 4.34), and the Pulse Output option will be temporarily disabled.
To test the output, enter a value in the Pulse Count eld, and press “Set Output.” The value in the Live Value
eld will decrement to zero in accordance with the programmed pulse duration.
