VIEWING

 

AND

 

EXPORT

. Whereas the Mark II meter offered the ability to 

retrieve a single waveform for each chord, the Mark III meter offers the ability to output a 
succession of waveforms for each chord. With Daniel MeterLink connected to the meter 
via the optional Ethernet, several waveform updates per second are possible.

LOG

. In addition to the hourly, daily, audit, and alarm logging capabilities offered by 

the Mark II, the Mark III meter adds system log capability to provide more detailed 
information on the health and status of the meter.

FILES

. The Mark III optionally exports log data in industry-standard and 

highly-flexible XML format. This allows the Mark III log files to be forward compatible with features 
that may be added in the future. The files are then optionally transferred to the PC using Daniel 
MeterLink in compressed format for fast transfers.

DATE

 

TIMESTAMP

. The Mark III meter checksums the 

configuration parameters and maintains a checksum change date timestamp for easy 
determination of a configuration change. Both checksum value and date timestamp are 
audit logged for traceability. They are also Modbus-readable for remote monitoring.

CONFIGURATION

 

FEEDBACK

. When using Daniel MeterLink to configure a 

Mark III meter, informative messages are displayed when trying to set an invalid 
parameter configuration. For example, when trying to set a data point to a value outside 
the point’s valid range, a message is displayed identifying the data point, the valid range, 
and the invalid value.
