You are the new owner of a 5000 ct portable digital multimeter and we thank you for your 
choice. 
 
This instrument complies with the specification set out in the IEC 61010-1 + A1 + A2, 
concerning safety requirements for electronic measuring apparatus. To get the best service 
from this instrument, read carefully this user's manual and respect the detailed safety 
precautions. 
The contents of this manual must not be reproduced in any form whatsoever without our 
consent. 
 

 

 

-   This device can be used for measurements on category 

ΙΙΙ installations, for voltages 

never exceeding 600 V (AC or DC) relative to the earth. 

 
-  Definition of overvoltage categories (see. publication IEC 664-1) : 
 
 CAT 

I :  The  CAT  I  circuits are protected by safety measures limiting transient 

 

overvoltages to appropriate low level. 

  

 

Example : protected electronic circuits 

 

CAT II :  The CAT II circuits are power supply circuits of appliances or portable  
   

equipment with transient overvoltages of an average level. 

  

 

Example : appliances and portable equipment 

 

CAT III : The CAT III circuits are power supply circuits of power equipment with  

  

high transient overvoltages.  

  

 

Example : fixed installation or industrial equipment 

 

CAT IV : The CAT IV circuits may comprise very high transient overvoltages.  

  

 

Example : primary supply level 

 
∗

  When using this multimeter, the user must observe all normal safety rules concerning: 

- protection against the dangers of electric current. 
- protection of the multimeter against misuse. 

 

∗

  For your own safety, only use the test probes supplied with the instrument and, 

check, before use, that they are in good working condition.

Test equipment risk assessment

  :

 Users of this equipment and/or their employers 

are reminded that Health and Safety Legislation requires them to carry out a valid 
risk assessment of all electrical work so as to identify potential sources of electrical 
danger and risk of electrical injury such as from inadvertent short circuits. Where the 
assessment show that the risk is significant then the use of fused test leads 
constructed in accordance with the HSE guidance note GS38 "Electrical Test 
Equipment for use by Electricians" should be used. 
 

∗

  Never exceed the protection limit values indicated in the specifications for each type of 

measurement.
