5.3.1.4.  Setting VT ratio 

For 

NPV systems

 the meter can be interfaced also with step-down transformers in the 

equipment under test. It can display the value of he voltages present on the primary 
winding of these transformers. To do this it will be necessary to set the value of the 
transformers’ windings ratio 
 
1.  Move the cursor using arrows keys on field relative to “

VT Ratio

” , marked it with blue 

background. 

2. Use 

F3

 or 

F4

 keys (alternatively touch 

MOD(+)

 o 

MOD(-)

) for selection of desired value 

from 

1

 to 

3000

. Leave the default value “

1

” if no voltage transformer is present on 

installation. 

3. Press 

SAVE

 or 

ENTER

 keys (or the smart icon 

) to save the selected option and 

confirm by “Ok”. This selected parameter will be present also after  turning off the 
meter. 

4. Press 

ESC

 key (or the smart icon  ) to to quit without saving any modification.
