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.
