: Four-terminal, Kelvin-type.
for approx. 15 minutes before the thermal
protection activates.
At 10 A or less, there is not a limited time for
continuous operation.
: Protects all sensitive components, avoiding any
damage due to overheating.
: R < 0.5 mΩ: ± (0.50% of reading + 2 ULSD*)
R ≥ 0.5 mΩ: ± (0.20% of reading + 2 ULSD*)
* Units of the Least Significant Digit.
: Digital direct reading of very low resistances in the
alphanumerical display, with up to 4½ digits. Very
fast and accurate measurements.
shows the result. The bargraph indication is
especially useful when measuring inductive loads,
so that the operator can verify easily when the test
current has been stabilized.
