Megger DLRO 10

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.

The Megger DLRO10HD is well suited to measuring thick conductors, bonds and quality of welding because of its 10 A range for resistance values up to 250 mA. Augmenting Megger's DLRO10 and 10X range the DLRO10HD combines ultimate simplicity of operation with a rugged IP65 case designed for stable ground and bench operation. The unit is powered from either its rechargeable battery or line power making it suitable for continuous testing in production line/repetitive use environments. Rotary switch controls are simple and easy to operate in all weather conditions and with gloved hands. A large, clear, backlit LCD display is easy to read from a distance. The DLRO10HD provides significantly enhanced compliance and is capable of delivering 10 A into measurements up to 250 mA and 1A into measurements up to 2.5 A. The duration of each test may be up to 60 seconds.
 

The DLRO10HD is rated CAT III 300 V. A range of test leads is available to suit the application.
