Megger EL6-C - Extension Lead Connect 6.0m These extension leads are designed to fit any of these test leads: TL1.5-C TL3-C TL3-C-BT51 TL6-C TL6-C-BT51 Note: These extension leads will not fit any of the leads fitted with indicator lightsThis 6m long duplex connect extension lead is designed to extend the duplex connect test leads that are without indicator lights.More than one extension lead can be used to create even longer test lead lengths. However the overall lead resistance must be taken into account. The higher the overall loop resistance, including the test piece, the lower the maximum test current available will be.Any 10A DLRO instrument fitted with a pair of 3 m test leads and any test lead terminations (duplex probes or kelvin clips) can have up to 2 x 6 m extension leads used and still be able to supply 10 A test current. This is because the overall resistance of this combination is below the 100 m ohm lead resistance maximum specified.Duplex connect test lead system for use with any Megger 10 A DLRO and BT51 instrumentsThe Megger DLRO duplex connect four terminal test lead system is designed to provide the most cost effective and convenient way to provide the user with all of the test lead terminations and lead lengths required for the many different applications encountered in low resistance testing.At the center of this unique test lead system is a bespoke connector allowing terminations such as kelvin clips or duplex test probes to be changed as required. There are two connector versions, one being fitted with indicator LEDs that operate with the DLRO10 range of instruments. The indicator LEDs provide enhanced safety and convenience with indications as follows:DLRO10, DLRO10X, DLRO10HD and DLRO10HDX Warning of connection to hazardous live voltage (Not DLRO10X, warning is given on the display) When continuity is made When a test complete and meas
