USING "DATA MEMORY" 

Any  value  (last  value,  maximum  value,  minimum  value)  obtained  immediately  before 
releasing the measurement button is automatically stored. 
The stored values can be displayed as follows: 

-

 

pressing the indicator once will display the last "LA" value  

-

 

pressing the indicator a second time will display the maximum "UP" value 

-

 

pressing the indicator a third time will display the minimum "dn" value 

 

 

Data memory 

When  moving  the  function  selector  to  "rpm  contact"  the  maximum  and  minimum  value  and 

the measured data will not be stored, only the last value.  
If you press the measurement button "D" (side) while checking the measured values, all the 

data will be erased and the instrument will re-measure and store data.

REMOVAL AND REPLACEMENT OF BATTERIES 

If the instrument is not going to be used for a long period of time, it is advisable to remove 

the batteries. 
When the batteries are low, the battery symbol appears on the display  

1.

 

Slide the cover off the back of the device and remove the batteries.  

2.

 

Install new batteries (4X1, 5V AA) correctly and close the lid 

 
 
 

 

Precautions  

 

Do not dispose of batteries with other waste but disposed of them through appropriate 

channels so as not to pollute the environment. 

 

Use only Alkaline batteries. 

 

If the instrument is not going to be used for a long period of time, remove the batteries 
to prevent them from losing power.
