APPLICATIONS
•    The DLRO10HDX measures low resistance values in applications ranging from railways and aircraft to the resistance of components in the industry and is well suited for measuring thick conductors, bonds, and quality of welding because of its 10 A range for resistance values up to 250 mW.
•    Any metallic joint can be measured but users must be aware of measurement limitations depending on application (For example, if a cable manufacturer plans to make resistive measurements on a thin wire, a low test current should be selected to prevent heating the wire thereby changing its resistance.)
•    Measurements on electric motors and generators will be inductive and require the user to understand the inductive mode and charging process before a correct result is achieved.
•    Electromagnetic noise induced into the leads can interfere with reading. A noise symbol alerts the user and prevents a measurement when the instrument detects noise above its threshold.
•    When dissimilar metals are joined a thermocouple effect is created. Users should select a bidirectional mode to ensure the cancellation of this effect. The instrument measures with current flowing in both directions and averages the result.
