For each test current, ranges are automatically selected for optimal reading.

Output voltage
Up to 10 Vd.c. (open circuit) @ 1 A. getting a fast stabilization in the measurement of great transformers.

Measurement principle
Four-terminal, Kelvin-type.

Continuous operation time
At 100 A this equipment may be used continuously for aprox. 15 minutes before the thermal protection activates. At 10 A or less, there is not a limited time for continuous operation.

Protections
The micro-ohmmeter has protections of fast action and by overheating that protects all the sensitive components.

Basic accuracy
± 0,20 % of reading ± 0,05 % of range.

Advanced features
Digital direct reading of very low resistances in the alphanumerical display, with up to 4½ digits. Very fast and accurate measurements.

 Test current measurement
Although the current is digitally measured, an analogue taut band instrument show the result  in order to facilitate the evaluation. This is specially useful when measuring inductive loads, so that the operator can verify easily when the test current has been stabilized

Serial data output
RS-232 @ 4800 bps. Suitable for data collection in an external serial printer, computer or data-logger.

Environmental protection
IP54 with closed lid.

Safety class
Meets the requirements of IEC 61010-1/1990, IEC 61010  1/1992 amendment 2
