RMO100G                                                                                                                                                              Getting started 

 

 

During the test, both green and red LEDs flash alternately. The display shows test curent  
(here 

100A

) and the current value of the measured resistance (

94,2

µΩ

). The time passed since                     

the test begining is also shown on the display (

00:35

).   

 

                                           

 

 

Upon completed test (due to expire of selected time or due to push to the 

STOP

 button) at selected 

memory location the last measured result will remain registered. By pushing 

Ω

 button current test result 

is stored in internal memory. 

 

Note:

    

In case of PC and DV-Win software use during the test, all performed measurements will be 

registered. Results will be shown in a table in Excel format with option of additional edit and    
graphic presentation. 

 

Using DV-Win after testing for transfer of results from selected internal memory location to PC, it is 
possible to transfer only the result of the last test. 

 

To stop the test prematurely, press the 

STOP

 

button at any time during the test. The current will 

immediately drop to 0 A.

Measurement procedure 

 

Turn on RMO100G with the power switch on the test set. The display shows the 

Single

 menu. Go to 

CC

 

menu by pushing 

SET

 button twice or using 

RIGHT

 button four times, 

DOWN

 button, 

RIGHT

 button three 

times and then 

DOWN

 button.

during the test  

 

Using  RMO100G  with  current  clamp  meter  it  is 
possible  to  make  safer  measurement  of  breakers 
with  both  sides  of

 

the  breaker  grounded. 

Measuring  the  current  through  the  ground 
connection  and  reducing  this  value  from  the  total 
current is an additional safety feature. 
When connecting current clamp meter pay 
attention that current circuit of the current clamp 
meter is enough far away form the rest of current 
circuits. In that way electromagnetic interference is 
prevented. Distance between current cables must 
be more than 10 cm.
