Megger DLRO10HD + DH4-C Lead Set
Includes: DLRO10HD Dual Power 10A Low Resistance Ohmmeter, DH4-C Connect Duplex Handspikes, Lid-Mounted Test Lead Pouch, DLRO10HD User Guide on CD, Warranty Book.
The Megger DLRO10HD enhances Megger’s existing family of 10 Amp DC low resistance ohmmeters. This heavy duty model combines simplicity of operation with selected high power ranges and the ability to simultaneously make measurements and charge the battery from line power.
This instrument provides significantly enhanced compliance and is capable of delivering 10 A while measuring up to 250 mΩ and 1 A while measuring up to 2.5 Ω. In the high current 10 A modes test current is maintained for up to 60 seconds.
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 mΩ. The instrument provides five test modes each of which is selected through a simple rotary control.
The five operating modes include two automatic modes that sense connection of the probes to minimise test time and increase productivity. To overcome thermal EMFs current is passed through the unit under test in both directions and the resulting resistance averaged.
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.
Interchangeable test lead terminations.
High or low output power selection for condition diagnosis.
Rechargeable battery or line power supply, continuous operation, even with dead battery.
10 A for 60 seconds, less time waiting to cool, great for charging inductance.
High input protection to 600 V, inadvertent connection to line or UPS voltage will not blow a fuse.
Heavy duty case: IP 65 lid closed, IP54 operational (battery operation only).
Rotary switch selects one of five test modes, including auto start on connection.
Although the DLRO10HD is not designed as transformer ohmmeter, it is fitted with a test in progress lamp associated with the TEST button, which indicates that current is flowing in the C1-C2 loop. This lamp and a warning triangle on the LCD will flash at end of a test on an inductive load whilst a discharge current is still flowing and will stop flashing when the current has decayed to less than 1 mA.
