  • Page 8: Safety

    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.

    This is done by selection of the appropriate options in MENU – Measurement mode. 3.1.1 Selection of the type of object The MMR-630 meter permits selection of one of the three types of objects: The measurement marked with the symbol is the shortest measurement (3s) and its purpose is to test objects of purely resistance-related character.

  • Page 18: Flow Of Current

    If the single-direction flow of current is selected the resistance value R is not displayed. 3.1.3 Measurement triggering The MMR-630 meter has three modes of measurement triggering: normal, automatic and contin- uous.  In the normal mode one measurement of resistance is performed.

  • Page 19: Saving To Memory

    3.1.5 Measurement range selection For the purpose of measurement of the resistance of the object the MMR-630 meter applies measurement currents within the range between 0.1mA and10A. The measurement range and thus the measurement current may be selected automatically or manually.

    When the charger power supply cable is plugged into a socket one of the following screens is dis- played. If the charge of the accumulators does not exceed 50%, then the a) screen is displayed. If the charge of the accumulators exceeds 50%, then the b) screen is displayed. OPERATING MANUAL MMR-630 Revision 1.6...
