Megger have replaced the old Duplex handspikes supplied with their 10A ductors. They now come bundled with a Duplex connect test lead system. These duplex test leads are fitted with hook terminations for connecting to an instrument and a connector plug equipped with ultra-bright LED indicator lights viewable from any direction. Test connection terminations are supplied separately. The duplex connector incorporates a locking ring to prevent test connections being pulled off in use.
The 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 centre 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 and DLRO10HD
Warning of connection to hazardous live voltage.
When continuity is made.
When a test complete and measurement is on instrument display.
DLRO10X adds
Indication of pass / fail to user set test limits.
All of these important indications are therefore seen near the point of connection without needing to view the instrument display. There is even a 6 m extension lead to provide the ultimate in flexibility.

Duplex Probe 1 - connect | Order part number: 1006-450
Description
Duplex connect handspike with sprung loaded tips fitted with a connector socket for easy connection to any connector test lead. Replaceable probe tips have hardened needle points, gold plated for excellent low resistance contact. Tips are sprung to provide 1.3 kg of force using stainless steel springs.
Ideal for general applications where a good reliable connection is required on none coated or corroded surfaces. To further limit the possibility of damage to test piece waffle tip, sometimes referred to a serrated tips are available as an option.
Maximum current rating: 10 A
Connector to probe tip resistance: 14m ohm
Probe spacing between P and C tips: 6 mm
Will fit Any duplex connect test lead and extension lead.
DTP1-C
Duplex Twist Probe 1 - Connect | Order part number: 1006-449
Description
Duplex connect handspike with sprung twisting tips fitted with a connector socket for easy connection to any connect test lead. As the probe is pressed onto the test piece the tips compress and twist at the same time providing 2.4 kg of spring force. Probe tips are hardened and tempered before four equal-spaced flats are ground to provide a square shape tip, making these probes ideal for cutting through surface coatings or corrosion on test piece for a good contact.
To assist reliability the probes internal electrical connections are assisted by using an innovative volute spring eliminating the need for a separate current carrying brad.
Maximum current rating: 10 A.
Connector to probe tip resistance: 14m ohm.
Probe spacing between P and C tips: 10 mm.
Will fit Any Duplex Connex test lead and extension lead.
KC1-C
Kelvin Clip 1 - connect | Order part number: 1006-447
Description
Duplex connect Kelvin Clip 1 is a heavy duty clip for general purpose applications.
Maximum current rating: 10 A.
Connector to probe tip resistance: 14m ohm.
Clip capacity: 40 mm.
Will fit any duplex connect test lead and extension lead.
CP1-C
Concentric Probe 1 - connect | Order part number: 1006-448
Description
Duplex connect concentric handspike with sprung loaded potential tip fitted with a connector socket for easy connection to any connector test lead. The C connection is made via an outer hardened and tempered steel crown with two contact points or tips.
Ideal for general applications where a good reliable connection is required on none coated or corroded surfaces. The long probe length and small diameter makes this probe ideal for reaching deeply recessed terminal screws. There are also applications where connection to rivet heads or screw/bolt heads are required.
Maximum current rating: 10 A.
Connector to probe tip resistance: 10m ohm.
Probe tip spacing: Between two outer C tips 7.6 mm.
P tip central between two C tips with 3.8 mm spacing.
Probe dimensions: From finger guard to tip 110 mm.
Diameter is tapered from 1 4mm nearest the finger guard to 1 mm at tip crown.
Will fit Any duplex connect test lead and extension lead.
