WIRING TEST
Advanced
Runs the test to check that the DME D305T2MID is connected correctly - See wiring test
COMMANDS MENU
– The commands menu permits the execution of occasional operations such as resetting measurements, meters, counter, etc.
– If the Advanced-level password has been entered, the commands menu can also be used to perform some automatic operations that are useful for configuring the instrument.
– The following table lists indicates the functions available in the commands menu, divided by access level required.
– Once the required command has been selected, press
to execute it. The device will prompt for a confirmation. Pressing
again will execute the command.
– To cancel the command execution, press MENU.
– To quit the commands menu, press
and
simultaneously.
WIRING TEST
– The wiring test permits verification of the correct installation of the energy meter.
– In order to run the test, the energy meter must be connected to an active system with the following conditions:
• Three-phase system with all phases present (V > 187VAC PH-N)
• Minimum current flow in each phase > 1% of the CT full scale set
• Positive flow of energies (i.e. a normal system where the inductive load draws power from the supply).
– To launch the test execution, enter the commands menu and select command C.16, according to the instructions in the Commands Menu section.
– The test allows to verify the following points:
• Reading of the three voltages
• Phase sequence
• Voltage unbalance
• Reverse polarity of one or more CTs
• Mismatch between voltage/current phases
– If the test does not succeeds, the display shows the reason of the failure.
