RECALL MEASUREMENTS 

1.

 

  Press  the 

ESC/RECALL  MEM

  key.  The 

display  shows  a  screen  similar  to  that 
reported here to the side, which contains: 

 

The  number  of  the  last  memory 
location used 

 

The value of parameter P 

 

 

 

 

2.

 

  Press the arrow keys to select the memory location whose content is to be displayed.

 

3.

 

  Press the 

SET/DISPLAY MEM

 key to display 

the  measure  contained  in  the  selected 
memory  location,  the  display  shows  a 
screen similar to that reported here to the 
side. 

 

4.

 

  By pressing the arrow keys it is also possible to cyclically display (according to the mode in 

which  the  saved  measurement  was  performed)  the  leakage  current,  the  DAR  (Dielectric 
Absorption Ratio), the PI (Polarization Index), the capacitance and the number N of cycles.

 

 

 

 

5.

 

  Press the 

ESC/RECALL MEM

 key to go back to the previous screen and press the 

ESC/RECALL 

MEM

 key again to exit memory management.

RESET OF INSTRUMENT 

1.

 

  Turn on the instrument by pressing the relevant key 

2.

 

  Press and hold the 

SET/DISPLAY MEM

 key. After approximately 10 seconds, the instrument 

is reset and turns off 

7

 

CONNECTION OF THE INSTRUMENT TO PC 

The connection between the PC and the instrument is obtained by means of a serial port and the 
C232NG1 cable, supplied with the software pack. Before connection, it is necessary to select the 
COM  port  used  for  transmission  by  the  PC  and  the  correct  baud  rate  (9600).  To  set  these 
parameters, launch the management software and consult the program’s help on line. 

 

 

 

CAUTION 

 

 

 

 

The selected port must NOT be used by other devices or applications (e.g. mouse, 
modem, etc…). 

 

The procedure for transferring saved data to a PC can be schematized as follows: 

 

1.

 

Turn on the instrument and wait for the initial screen to disappear 

2.

 

Connect the RS-232 cable to the instrument and to a COM port of the PC 

3.

 

Launch the data management program on the PC 

4.

 

Follow the instructions of the software’s help on line
