Frequency test mode

The Mark III meter provides a mode of operation for individually testing the frequency output signal pairs. Entering, configuring, and exiting this mode is accomplished by setting data points using the Daniel MeterLink Tools - Outputs Test screen as described in the table below. Note that when a frequency output pair is in the test mode, the frequency output is considered to be invalid since it does not represent the selected frequency content.

Options:

Start(Stop)

• Click on the Start button to enter the test mode (TRUE) (Note: the Start button will become

the Stop button after clicking on it.)

• Click on the Stop button to exit the test mode (FALSE) (Note: the Stop button will become the Start button after clicking on it.)

• For further information, see timeout discussion below and Daniel MeterLink online help.

The maximum length of time that a frequency output pair can remain in the test mode is specified via the NonNormalModeTimeout data point. Note that this data point applies to both frequency output pairs (as well as various other tests). The NonNormalModeTimeout data point can be changed using the Daniel MeterLink Edit/Compare Configuration screen. It can be set within the range [1, 30 min] and has a default value of 2 min.
