Connection Verification and Correction

Once the measurement is configured and the voltage and current
inputs are connected to the system under test, go back to the Meter
mode and use the Verify Connection touch button to confirm the
connection.
The verification detects:
•
Too low signal
•
Phase rotation for voltage and current
•
Inverted current probes
•
Wrong phase map
Push  (Show Menu) to navigate through the Verify, Correct
Digitally, and Phasor screens.

1. Push  (Show Menu) and select Verify.
2. Push  to toggle between Generator Mode and Motor
Mode.
Usually the current flow direction is toward the load. Use
Motor Mode for these applications.
Use the Generator Mode when the current sensors are
connected intentionally to the generator. An example is during
the time that energy goes into the grid from a regenerative
braking system of an elevator or on-site wind turbines.
The current flow arrow indicates the correct flow:
•
Normal condition is shown in Motor Mode with a black arrow
pointing upwards
•
In Generator Mode the black arrow is pointing downwards.
•
If the arrow is shown in red, the current flow direction is
inverted.
If the Logger is able to determine a better phase map or polarity, push
 (Auto Correct) to apply the new settings.
Auto Correct is not available if the algorithm is not able to detect a
better phase map or when no errors are detected.
It is not possible to detect all incorrect hook-ups automatically.
You must verify the suggested modifications carefully before
you apply the digital correction. Applications with single-
phase energy generation can deliver the wrong results when
you apply the Auto Correct feature.
