MMR-630 low resistance meter with calibration certificate WMPLMMR630

Low resistance meter providing very high accuracy (measurement resolution 0.1 µΩ). High measuring current for individual sub-ranges and appropriate operating modes enable measurements of inductive objects (transformers, motors). The versatility of use is determined by special functions that allow the device to be used also in the production cycle for serial measurements, for example when controlling large batches.

Measurements of resistive objects:

Measurements of inductive objects:

• windings of motors, transformers, low-resistance coils,
• automatic measurement range selection or manual (measurement of inductive objects),
• four-wire method.

Selection of the measurement mode adapted to the type of the measured object:

• quick measurement (3 seconds) for measuring resistive objects,
• extended measurement for testing inductive objects (short mode possible with slightly limited accuracy); with automatic unloading of the object after measurement.

Selection of the measurement mode depending on the application (e.g. control of product series):

< li> measurement in normal mode - triggered each time the "START" button is pressed,
• measurement in automatic mode - the device waits for all four test leads to be connected to the object, and then automatically starts the current measurement in one or both directions and calculates the average value of the resistance,
• measurement in continuous mode - the meter repeats successive measurement cycles with breaks every 3 seconds (for resistive objects), or performs the measurement continuously (for inductive objects).

Window mode:

• allows you to set the upper and lower limits between which the measurement result should be placed, sound signaling of going out of range.

Possibility to perform measurements even with disturbances five times higher than the measured signal.

Memory of 990 measurement results with the possibility of sending them to a PC.

Electrical safety:

• measurement category: CAT III 300 V
