Click the
Start
button to enter Test mode. Each output has its own start button, so each available
output can be tested one at a time. The frequency and current outputs will not be updated until
the end of the next batch cycle. Once the Test mode LED turns green, the output values
displayed represent the values the outputs are driving under test.
The frequency outputs for both the A and B channels are displayed. If
Channel B zero on error
is
selected in the Field Setup Wizard the Channel B phase will show zero because the frequency
output is considered invalid during test mode.
The K-Factor and Inverse K-Factor will be displayed for the frequency outputs configured for
Volumetric flow rate. The values will be displayed next to the label for the associated frequency
output.
To set the digital outputs to a known state, select the Test High or Test Low for the appropriate
digital output and click the
Start
button for the digital output. Once the Test mode LED turns
green, the value displayed for the outputs will represent the values the outputs are driving
under test.
The timeout for each output in test mode is reset by Daniel MeterLink each time the values are
updated. As long as this dialog is open with an output in test mode, the output will remain in
test mode or until the
Stop
button is clicked to end the test.
In the event communications are lost between Daniel MeterLink and the meter (before a test
mode is stopped), the meter will automatically end the test mode after the
NonNormalModeTimeout
has expired. This can be from 1 to 30 minutes depending on its
settings. By default, the timeout is set to two minutes.
The Output setting can only be changed while out of Test mode. To end the Test mode, click
Stop
and wait for the end of the batch and the Test mode LED to turn gray to indicate the
Outputs are driving live values.
Click
Cancel
to close the dialog box. If the meter is currently in Test mode when Cancel is clicked,
Daniel MeterLink will first end the test mode before returning to the Main Screen.

Configure HART outputs
Configure the HART outputs of the Daniel Ultrasonic meter. For additional information refer to
the
HART Field Device Specification Manual
(P/N 3-9000-761).
5.8.1
Configure the four dynamic variables
•
Primary - set to match the Content for Current Output 1
•
Secondary - set to match the Content for Current Output 2
•
Third - select from the following variables: Uncorrected flow rate, corrected flow rate,
Average flow velocity, Energy flow rate, Mass flow rate Pressure and Temperature
•
Fourth - select from the following variables: Uncorrected flow rate, corrected flow rate,
Average flow velocity, Energy flow rate, Mass flow rate Pressure and Temperature
