Temperature_Unit CELSIUS Choose between Celsius or Fahrenheit units for CELSIUS Temperature Note that all Temperature settings in the FAHRENHEIT Trend_Settings section and Modbus will always be in Celsius This method produces a single value of unbalance It is widely used in North America The IEC unbalance method considers both three phase magnitudes and the angles between the phases Itis limited to the fundamental voltage or current only it does not take into account any harmonic voltages or currents This method produces two values of unbalance zero sequence unbalance and negative sequence unbalance Itis widely used throughout the world The GB unbalance method is similar to the IEC unbalance method but includes time averaging features Itis used in China Flicker_Lamp_Voltage 230 Choose between 120V 60Hz or 230V 50Hz incandescent Page 79 of 107 PQube User Manual 2 0 0 lamp voltage for Flicker measurements according to IEC 61000 4 15 Rotation Convention _On_ Vectors Screen The rotation convention used on the Vectors display screen CLOCKWISE Counter clockwise COUNTER_CLOCKWISE NOTE This tag does not affect measurements or rotation a LL errors To fix rotation errors swap any two phases in the Adjust_ Phase Connections section Voltage Current Vector Voltage Current Vectors Minimum_Current_Display_In_Percent_Of_Rated_Current 0 A nonzero number here will cause any current reading to be O t
