Multi purpose resistance meters Digital ohmmeters MR 501 Multi purpose digital ohmmeter The MR501 milli-ohmmeter is a universal digital ohmmeter, which is used in general resistance measurement applic-ations. This includes the resistance measurement of small transformers and motors, coil resistances of contactors, relays and lifting magnets, contact resistances (also available with 20 mV limitation), testing of fuses, etc. Its robust design, small size and the possibility of battery operation also allow a mobile use. The instrument can additionally be protected against direct connection to voltage (230 V), in order to avoid that it is destroyed in the case of heat-up. The MR 501 performs a quotient measurement with reference to internal reference resistances. This ensures the high accuracy of the measurements over long periods. In case the resistances of the feed lines connecting to the test object are too high, two LEDs are ON on the front panel. In this way a measuring error, which would remain unnoticed, can be avoided. In particular with low-resistance objects this error occurs quite frequently and mostly remains unnoticed. Possible thermoelectric forces can be compensated by means of a potentiometer. To really determine the thermoelectric forces the test object remains connected and the measuring current is turned off by pressing the corresponding key. However, it will rarely be necessary to perform this correction. • Measuring range from 10 mQ -10 MQ, decadic • Dual slope quotient, 4-pole Available enhancements • Accumulator operation performed by an internal battery • 20 mV limitation • 230 V AC / DC protection protection against direct high voltage input email: sales@schuetz-messtechnik.com Range End value Res.
