Declarations of conformity

Measurement of resistive object 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 object type:
- coils (motors and transformers), low resistance coils.
Range selection autoranging or manual (measurement of inductive object 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 - since 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:
- 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 20 mV and to show noises from 20 to 100 mV (so in edge conditions even 5 times higher than measured drop of potential).
Memory store for up to 990 results and a communications facility for transferring data from the device to a PC.

Electric security:
- type of insulation: double, according to EN 61010 - 1 and IEC 61557
- measurement category: CAT III 300 V acc. to EN 61010 - 1
- protection class acc. to EN 60529: IP54

Other technical data:
- meter’s power supply: battery package SONEL/Ni-MH 4,8 V
- battery charging time: approx. 2,5 hours
- number of measurements with the current of 10 A: 300
- auto-off time: 120 seconds
- immunity to interference: additional error ≤1% for voltage 50 Hz ≤100 mV RMS
- maximum leads resistance for the 10 A current: 0,1 Ω
- maximum inductance of the tested object: 40H
- accuracy of the test current: ±10%
- resistance measurement time:
- with the selected resistive object type with the bidirectional current: 3 seconds
- with the selected inductive object type, dependant on the resistance
and inductance of the object: a few minutes (max. 10)
- dimensions: 295 x 222 x 95 mm
- weight: approx. 1,7 kg

Rated operational conditions:
- operation temperature: 0...+40°C
- storage temperature: -20...+60°C
