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.
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.
