Equally at home in the laboratory, the workshop or in the field, on the bench or on the ground, Megger’s new heavy-duty DLRO10HD low resistance ohmmeter combines rugged construction with accuracy and ease of use. It features an internal rechargeable battery and can also operate from a mains supply, even if the battery is completely flat.
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 mΩ and 1 A into measurements up to 2.5 Ω. The duration of each test may be up to 60 seconds.
The DLRO10HD is rated CATIII 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. The DLRO10HD provides five test modes each of which is
selected through a simple rotary control.
The green resistance ranges on the keypad indicate low output power (<0.25 W) outputs. Red ranges indicate higher
2.5 W (1 A) and 25 W (10 A) power outputs.
