As the EL light will consume much power it only has to be 

turned on if necessary. 
 

4.16 Battery information 
 

Two AA size alkaline batteries are needed as power 
source. After several hours’ usage of the preset batteries, 
the battery symbol on the screen will be shown as

If battery capacity runs out, the battery symbol 

will 

be shown and it will begin to flash. In this case, the 
batteries should be replaced. 
If the instrument isn’t used for a longer period, the batteries 
have to be removed. 

 
 

 
 
 

4.17 Auto Power off 
 

The instrument features an “auto power off” function 
designed to conserve battery life. If it is not in use for 5 
minutes or more, it will turn itself off. If the voltage of the 
battery is too low this function will also work. 
 

4.18 System reset 
 

The

 

key has to be pressed while powering on the 

instrument: factory defaults will be restored. 
All the memory data will be cleared during system reset. 
The only time this might be helpful is if the parameter in 
the instrument was somehow corrupted. 
 

4.19 Connection to PC 
 

This instrument is equipped with a RS-232serial port. 
Using the accessory cable, the instrument has got the 
ability to connect to a PC or an external storage device. 
Measurement data stored in the memory can be 
transferred to the PC through the RS-232 port. For detailed 
information of the communication software and its usage, 
refer to the software manual. 
 

5. Menu operation 

 

Both, presetting system parameters and the additional 
function are verified by menu operation. On the 

measurement screen, the 

 key has to be pressed to get 

into the main menu.  
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
                                                                                                 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 

5.1 Enter the main menu 

To enter the main menu, the key 

 has to be pressed to 

activate the menu items tab while being on the 
measurement screen. To turn back to the previous screen, 

the key 

 has to be pressed again. 

 

5.2 Enter the Sub menu 

The  

 key has to be pressed to enter the submenu 

screen while the submenu item is selected. 
 

5.3 Change the parameter 

The  

 key has to be pressed to change the value of a 

parameter while the item is selected on the parameter set 
screen.
