VFD-ACV  & ACV  functions

Inputs are made through the test leads terminals. 

 Hz

VFD-ACV

 function is to deal with VFD (Variable Frequency Device) 

signals. It, however, further pre-selects  the most appropriate voltage-

ranges  and  thus  the  Hz  trigger levels to best cope with most VFD-

Voltage and VFD-Frequency applications.

Note: The  Hz  trigger  level is determined by the 

AC/DC+AC Voltage 

or  Current

  function-range  being  in use.  Press  

RANGE 

 button  to 

select different function-ranges and thus trigger levels manually.

Inputs  are  made  

through  the  test  

leads terminals. 

Defaults at 

DCV
