Continuous operation time
At 200 A this equipment may be used continuously for aprox. 3 minutes before the thermal protection activates.
At 10 A or less, there is not a limited time for continuous operation.
Basic accuracy
R < 0.5 mΩ: ± (0.50% of reading + 2 UUD*).
R ≥ 0.5 mΩ: ± (0.20% of reading + 2 UUD*).
* Units of the Least Significant Digit.
Advanced features
Digital direct reading of low resistances in the alphanumerical display, with up to 4½ digits. Very fast and accurate measurements.
Thermal protection
Protects all sensitive components, avoiding any damage due to overheating.
Environmental protection
IP54 with closed lid.
