- Gain: 1000 °C/V or 1000 °F/V
- Offset: 0 °C or 0 °F
Events
The Events screen shows the settings for:
•
Dip
•
Swell
•
Interruption
•
Inrush Current
The Dip, Swell, and Interruption settings on this screen are information
only, but you can edit the Inrush Current setting:
1.
Highlight Inrush Current.
2.
Push to open a numeric keypad.
3.
Use / to input a new limit value.
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
•
Voltage level mismatch with nominal voltage setting
•
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.
Verify
1.
Push (Show Menu) and select Verify.
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.
