The Megger DLRO10HD 10A Digital Low Resistance Ohmmeter measures low resistance values in applications ranging from railways and aircraft to resistance of components in industry.
Any metallic joint can be measured you must be aware of measurement limitations depending on application.
Measurements on electric motors and generators will be inductive and require the understanding of the inductive mode and charging process before a correct result is achieved. The Megger DLRO10HD 10A Digital Low Resistance Ohmmeter is well suited to measuring thick conductors, bonds and quality of welding because of its 10 A range for resistance values up to 250 mΩ.
Electromagnetic noise induced into the leads can interfere with a reading. A noise symbol alerts you and prevents a measurement when the instrument detects noise above its threshold.
When dissimilar metals are joined a thermocouple effect is created. You should select a bidirectional mode to ensure cancellation of this effect. The instrument measures with current flowing in both directions and averages the result.
