Description:

Measurements of objects resistive in nature:
- welded and soldered connections, equipotential bondings, earthing conductors,
- contacts, welds of rails, conductors and cables,
- measurement according to the four-lead method.
Measurements of objects inductive in nature:
- motor windings,
- low-resistance coils.

Automatic or manual selection of measuring range (measurement of objects of an inductive nature).
Selection of measurement mode according to the type of measured object:
- fast measurement (3 seconds) for measurement of objects of a resistive nature,
- extended measurement for testing of objects of an inductive nature (accelerated mode, with slightly worse accuracy, available); with automatic discharging of the object after measurement.
Selection of measurement mode depending on application (including control of product series):
- measurement in normal mode - triggered when the “START” button is pressed,
- measurement in automatic mode - the instrument awaits connection of all four test leads to the object, after which it automatically starts measurement in one or both directions and calculates the mean resistance value,
- measurement in continuous mode - the meter repeats successive measurement cycles with breaks every 3 seconds (for objects of a resistive nature) or performs measurement continuously (for objects of an inductive nature)
Window mode:
- makes possible to set an upper and lower limit within the measurement result should remain; sound signal triggered when the result is beyond set range,
- capability of performing measurements even under disturbances of a value five times greater than the measured signal.
