RMO200                                                                                                                      Safety Instructions, Designated Use 

Operator Qualifications 

•   Testing with RMO200 should only be carried out by authorized and qualified   
     personnel. 
•   Personnel receiving training, instruction, direction or education on the RMO200      
    should remain under the constant supervision of an experienced operator while       
    working with the test set and the test object. 

Safe Operation Procedures 

•  Hazardous voltages of up to 400V can occur inside RMO200. Therefore is not 
    permitted to open RMO200. 
•   Before putting RMO200 into operation, check the test set for visible damages. 
•   Do not operate RMO200 under wet or moist conditions (condensation)

•   Do not operate RMO200 when explosive gas or vapors are present. 
•   The serial interface of RMO200 should only have external devices connected that  
    meet the requirements for SELV equipment according to EN 60950 or IEC 60950. 
•   If RMO200 is opened by the customer, all guarantees are invalidated. 
•   If RMO200 seems to be functioning improperly, please contact the IBEKO POWER       
    AB (refer to section ”Manufacturer Contact Information”). 
•   Do not use RMO200 without the extra protective ground (PE) cable set connected. 

Power Supply 

•   Supply RMO200 only from a power outlet that is equipped with protective ground . 
•   Instead of supplying RMO200 from phase – neutral (L1-N, A-N), it may also be  
    supplied from phase – phase (e.g., L1-L2; A-B). However, the voltage must not  
    exceed 240 V AC, please refer to section Technical Data.    

3 Designated Use 

The Micro OhmMeter RMO200 is designed for measuring contact resistances of non-
inductive test objects used in the electric power industry or similar branches. It is 
employed for resistance measurement during manufacturing, commissioning and  
testing of: 
 

ƒ

  power circuit breakers, 

ƒ

 interrupters, 

ƒ

 bar 

installation, 

ƒ

 cable 

splices, 

ƒ

 welded 

joints, 

ƒ

 grounding. 

Any other use of the RMO200 than the ones mentioned above is to be considered 
improper and will not only invalidate all customer warranty claims but also exempt the 
manufacturer from its liability for repair or exchange.
