be set from 0 to 150%. The 100% Scaling indicates the full scale value for the frequency outputs and can be changed from the Field Setup Wizard.

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 values displayed for the outputs will represent the values the outputs are driving under test.

For the frequency outputs, the frequency 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.

 

For Daniel Gas Ultrasonic meters, 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 NonNormalMode-

 

Timeout 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.

 

Entering, configuring, and exiting this mode is accomplished by setting data points using the

 

Daniel MeterLink Tools - Outputs Test screen as described in Table 6-14.

Options:

 

 

• Enter the integer percentage of full scale for the analog output within the range [0, 100 %]

 

 

where 0% corresponds to the minimum output (4 mA) and 100% corresponds to the

 

 

maximum output (20 mA).

 

 

Guidelines:

 

 

• The specified test value takes effect within one batch period of clicking the Start button

 

 

(see below).
