Programming the Turn Number:

This menu is available for CT-25 adapted devices. User enter

the turn number, which is the number of how many tour the current

cable has rounded into the CT-25. Numbers can be selected

between 1-20. Greater the number of turn means greater the

sensivity.

Note: 

If the voltage transformer is not used between the system

and  MPR-53/53S, voltage transformer ratio is entered as ‘1’.

Example:

 If a voltage transformer which has a ratio of 34.5KV/100V

is used between the system and MPR-53/53S; Voltage transformer

ratio is entered as 345. (34500/100)

Voltage Transformer Ratio Setup

In this menu, voltage transformer ratio is set between

0000,1 - 4000,0.

For erasing the values of min. and max. or energy counter,

In the measurement mode :

Monitoring and Erasing of  minimum, maximum and

energy values:

In this menu, values of min.,max. or energy counters are erased.

It saves the instantaneously measured min. and max. values of

MPR-53/53S into its memory. Please kindly look at to the section

of 

FUNCTIONS OF BUTTONS 

for min. and max. values.

 

 

Note :

 Measured electrical parameters which are saved to the

memory  are  not  affected  from  the  electric  interruptions.

In the “rESEt” menu; when you quit from all menus, if you confirm

the changes,min. and max. values of all parameters or energy

counter values are erased at the same time.

Enter the blinking digit value by scrolling UP/DOWN buttons.

Switch to the other digits by using SET button, use BACK button
