8.3.3.4 INTERHARMONICS 
A single inter harmonic frequency may be generated using the INTERHARMONICS screen. This 
screen allows insertion of any inter harmonic from 1Hz to 2400Hz in 1Hz steps.  The amplitude 
level of the harmonics range is from 0 to 20% of the programmed voltage.  To select the inter 
harmonics screen, press the menu screen until the MENU 2 screen appears as shown in Figure 
8-30.  Select INTERHARMONICS using the up or down key.

The inter harmonics screen will appear as shown in Figure 8-31.  This screen has the following 
parameters:

1.  REFERENCE  This field will enable the Inter harmonics generator if ON is selected and 
      will disable the inter harmonics generation if OFF is selected. 
2.  REF. COUPL  If turned on, the REF. VOLT will follow the programmed voltage value.  
3.  REF. VOLT   This field must be programmed to a value if REF. COUPL is off.  This 
      value has a range from 0 to 230 volts.  This value is set to a value 
      equal to the phase A voltage if the REF. COUPL is turned on. 
4.  VOLTAGE    This field programs the Inter harmonic level in percentage of the  
      REF.VOLT.  This value has a range from 0 to 20%
