Cầu đo điện trở 1 chiều MMR-620 & MMR-630
Measurement of resistive bject type
- welded and soldered connections, equipotential bonding, earth wire,
- terminals and connectors, rail welded joints, cables and wires,
- measurement 4-pole method.
Measurement of inductive bject type:
- coils (motors and transformers), low resistance coils.
Range selection autoranging or manual (m ement of inductive
bject type).
Selectable measurement mode adjusted to object type:
- for resistive objects - fast mode (3 seconds),
- for inductive objects - long mode with automatic discharge after measurements
(or with lower accuracy - shorter mode).
Selectable measurement mode adjusted to application:
- normal mode - after pushing „START” button,
- automatic mode - as test leads are connected to the object meters
automatically starts measurement with dual direction current flow and gives
average result - what eliminates eventual DC voltage on tested object,
- continuous mode - every 3 seconds for resistive objects or continuous
measurement for inductive objects.
Window mode:
.PNG)
- this option enables setting an upper and a lower limit between which the
average measurement result is bound to appear. The results outside of this
range will be indicated by two long audible signals and the symbols.
MMR-630 is designated not to be effected by interference up to 20mV and
to show noises from 20 to 100mV (so in edge conditions even 5 times
higher than measured drop of potential).
of 990 measurement results and with ability to transfer data to a PC
Electric security:
- EN 61010-1 and IEC 61557
- measurement category CAT III 300V acc. to EN 61010-1

and inductance of the object a few minutes (max. 10)
- dimensions 295 x 222 x 95 mm
- weight approx. 1,7 kg
