Digital output test mode
The Mark III meter provides a mode of operation for individually testing the digital 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.
The maximum length of time that a digital output pair can remain in the test mode is specified
via the NonNormalModeTimeout data point. Note that this data point applies to both digital
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.
