OPERATING MANUAL MMR-630   Revision 1.6 

Safety  

 

 

The MMR-630 meter has been designed to realise measurements of resistance of different kinds 

of  connections  (welded,  soldered,  contact  connections)  in  electric  installations.  The  results  of  the 
measurements determine the safety conditions of the installation. Therefore, in order to provide condi-
tions for correct operation and the correctness of the obtained results, the following recommendations 
must be observed: 

 

Before  you  proceed  to  operate  the  meter,  acquaint  yourself  thoroughly  with  the  present  manual 
and observe the safety regulations and specifications determined by the producer.

 

 

 

The  MMR-630  meter  has  been  designed  for  the  purpose  of  low-resistance  measurements.  Any 
other application than those specified in the present manual may result in a damage to the device 
and constitute a source of danger for the user. 

 

In  case  of  measurements  of  installations,  sub-assemblies  and  devices  under  a  dangerous  volt-
age, the MMR-630 meters may solely be operated by qualified personnel who are properly author-
ised  to  work  on  electric  installations.  Operation  of  the  meter  realised  by  unauthorised  personnel 
may result in damage to the device and constitute a source of danger for the user. 

 

Using this manual does not exclude the need to comply with occupational health and safety regu-
lations and with other relevant fire regulations required during the performance of a particular type 
of  work.  Before  starting  the  work  with  the  device  in  special  environments,  e.g.  potentially  fire-
risk/explosive environment, it is necessary to consult it with the person responsible for health and 
safety. 

 

It is unacceptable to operate the following: 

 

A damaged meter which is completely or partially out of order, 

 

A meter with damaged cable insulation,

 

  A meter stored for an excessive period of time in disadvantageous conditions (e.g. excessive 

humidity).

 If the meter has been transferred from a cool to a warm environment of a high 

level  of  relative  humidity,  do  not  realise  measurements  until  the  meter  has  been 
warmed up to the ambient temperature (approximately 30 minutes).   

  Before measurements may commence, make sure the cables are connected to the appropri-

ate measurement sockets. 

  Do not operate a meter with an open or incorrectly closed battery (accumulator) compartment 

or power it from other sources than those specified in the present manual. 

 

The meter’s inputs are electronically protected from power surge, as a result for example, of 
accidental connection to the power supply source:   

         - for all input combinations 

– up to 440VAC for 10 seconds.              

 

Repairs may be realised solely by an authorised service point. 

 

The device complies with the following norm: EN 61010-1 

 

 

 

Note: 

The manufacturer reserves the right to modify the appearance, accessories and 
technical data of the meter. 
 

 

 

Note: 

An  attempt  to  install  drivers  in  64-bit  Windows  8  may  result  in  displaying  "In-
stallation failed" message. 
Cause: Windows 8 by default blocks drivers without a digital signature. 
Solution: Disable the driver signature enforcement in Windows.
