INST = Instantaneous value

 

 Actual instantaneous value of reading, shown by default every time the page is changed

 

 

MAX = Highest peak

 

 Highest peak of the instantaneous value of the relative reading. They can be cleared using dedicated command (see reset menu).

 

 

MIN = Lowest peak

 

 Lowest value of reading. They can be cleared using the same command used for MAX values.

 

 

AVG = Average value

 

 Time-integrated value of reading. Allows showing measurements with slow variations.

Modifying parameters 

To modify the setting of one parameter, select it with 

▲and ▼

keys and then press       

 

There are two methods for modifying a parameter, depending on the type of parameter: 

 

Selecting a value in a list (for example, selecting SINGLE-PHASE from a list of available wiring connections). 

 

Modifying a numerical value, digit by digit (for example, entering a value for the date, time or VT primary). 

 

Selecting the value in a list 

To select a value in a list: 
1. Use the 

or 

keys to scroll through the parameter values until you reach the desired value. 

2. Press        to confirm the new parameter value. The entered value is stored. 

 

Modifying the numerical value 

When you modify a numerical value, the digit on the far right side is selected by default. To modify a numerical value: 
1. Use the 

or 

keys to modify the selected digit. 

2. Use the 

 or  

keys to shift to the next digit. 

3. Press        to confirm the new parameter value. The entered value is stored. 
 
- Each parameter is show with present value and the possible range values. 
 

NOTE:

 If you enter an invalid setting and press       , the message 

Value out of range

 will appear on display.
