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 DLRO10HDX provides significantly enhanced compliance and is capable of delivering 10 A into measurements up to 250 mΩ and 1 A into measurements up to 2.5 Ω. The duration of each test may be up to 60
seconds.
The unit is rated CAT III 300 V provided the optional terminal cover is fitted to the instrument. Details of which can be found in the ordering information panel of this data sheet.
