6.3 Calibrator Menu
Submenu contains parameters that affect generated signal.
1. Voltage sources GND
This parameter allows to connect Lo terminals of all voltage channels to GND. In practice this
means that Lo voltage terminals are grounded. By selecting an item from the list GndU Off and
GndU On type can be selected.
2. Current sources GND
This parameter allows to connect Lo terminals of all current channels to GND. In practice this
means that Lo current terminals are grounded. By selecting an item from the list GndI Off and
GndI On type can be selected.
It is recommended to ground all output channels (GndU On, GndI On). If the meter to be
calibrated has Lo terminal grounded, it is recommended to unground the corresponding
calibrator’s output to exclude ground loops.
Note
If neither the calibrator’s output, nor the meter’s inputs are grounded, signal/noise ratio can arise at
the calibrator’s output.
3. Phase unit
Sets the unit used for presentation the phase shift between the voltage and current output in the
power and energy generation modes. By selecting an item from the list Deg (º) and Cos (Lead,
Lag) unit can be selected.
4. Phase rotation
Phase rotation setting. By selecting an item from the list POS (standard phase) and NEG (reversed
phase) rotation can be selected.
