Dual hands probes
The DRM-4015 and LRM-4015HD probes are easy to use on any metallic surface.
Their spring loaded tips allows a good electrical contact on the conductor to
test. The next figure shows the DRM-4015 probes on a metallic surface. The
black dots (DRM-4015) or red dots (LRM-4015HD) should always be facing one
another while performing the test. This ensures that the voltage reading points
are inside the current injection points.
After multiple usages, the probe’s tips can start to round which leads to bad
electrical contact. To replace the pins, gently pull them out of the probe using
long noise pliers. Insert the new pins using the same technique.
