Megger DLRO10HD + KC1-TL3-C – DLRO10HD Digital Low Resistance Ohmmeter, 10A with Kelvin Clip 3m Test Leads

Megger DLRO10HD + KC1-TL3-C – DLRO10HD Digital Low Resistance Ohmmeter, 10A with Kelvin Clip 3m Test Leads

• Rechargeable battery or line power supply, continuous operation, even with dead battery
• 10 A for 60 seconds, less time waiting to cool
• Protected to 600 V without blowing a fuse, test lead live voltage warning light
• Heavy duty case: IP 65 lid closed, IP54 battery operation
• Simple rotary switch selection of five test modes, including auto start on connection

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.

Applications

The DLRO10HD measures low resistance values in applications ranging from railways and aircraft to resistance of components in industry. 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.

The actual safety CAT rating in use will always be the rating of the lowest part of the complete system For example if used with a DLRO10 without terminal covers the system will be unrated and must not be connected to live voltages above 30 V.

In this example using a DLRO10HD a terminal cover should also be.

Additional Features and Benefits

• Small, lightweight and portable – can be used in tight places, reduces the need for extra long leads and two person operation.
• Four terminal resistance method shows the true resistance of the item under test.
• Bright LED (DLRO 10) and LCD (DLRO 10X) displays are easily visible under all lighting conditions and reduce human error.
• Automatically applies forward and reverse currents which cancel out any standing voltages across the sample under test.
• Checks for undue noise during measurement, reducing the possibility of recording the incorrect result.
• Automatically detects continuity in P and C circuits, preventing erroneously high reading to be taken due to high resistance contact.
• Battery module has a battery condition indicator allowing the user to check the state of spare batteries without connecting to the instrument.
• RS232 connector on the DLRO 10X allows downloading of results in real time or stored for later retrieval.
