Memory of measurement result data

 

MPI-525 meters are equipped with the memory that can store 50,000 single measurement results. 

The whole memory is divided into 10 memory banks containing 99 memory cells each. Thanks to dy-
namic memory allocation, each of the memory cells can contain different quantity of single measurement 
results, depending on the needs. Optimal use of the memory can be ensured in this way. Each meas-
urement result can be stored in a memory cell marked with a selected number and in a selected memory 
bank. Thanks to this, the user can, at his/her option, assign memory cell numbers to individual meas-
urement  points  and  the memory bank  numbers  to  individual  objects  as  well  as  the  user can  perform 
measurements in any sequence and repeat them without losing other data. 

Memory of measurement result data 

is not deleted

 when the meter is switched off. Thanks to this, 

the data can be later read or sent to a computer. Also, the number of a current memory cell or memory 
bank is not changed. 

 

Remarks: 

 
- Results of measurements performed for all measuring functions can be stored in one memory cell.  
-

 

When autoincrementing of memory cell number is deactivated, a single result (group of results) stored 

into  the  memory  does  not  increase  automatically  the  number  of  the  current  memory  cell  in  order  to 
enable storing in this memory cell successive measurement results concerning a given measurement 
point (object). If series of measurements are made for one function, autoincrementing of memory cell 
number can be set in MENU. Such autoincrementing takes place after each case of data storing in the 
memory (activation of autoincrementing 

– point 2.1.5). 

-  Only  the  results  of  the  measurements  started  by  pressing 

START

  key  button  can  be  stored  in the 

memory (except autozeroing in low-voltage measurement of resistance). 
- Deletion of the memory is recommended after reading the data or before performing a new series of 
measurements that may be stored into the same memory cells as the previous ones. 

4.1  Recording measurement result data in the memory 

 

 

 
Press 

ENTER

 after completion of measurement. 

 

 

The frame indicates that at 
least one result is stored in 
the cell. 

The frame indicates at least one 
cell in the bank has measurement 
results stored in it. 

Type  of  measure-
ment  result  to  be 
stored 

 

 
The  cell  is  free  for  a 
given type of measure-
ment. 
 
There are 6 results or 
one result consisting 
of 6 screens in the 
cell.
