TEST FIXTURE
The ExLRT has an integrated Self-Test fixture. To test the ExLRT instrumentation, simply connect the
loop and joint cables to the ExLRT and clamp the loop couplers around the handles as shown.
NOTE:
The Self-Test fixture is manufactured out of stainless steel and is not intended to be used as
calibrated. The designed nominal value is 9.5mΩ but expect to see small deviations in measurement
for each ExLRT manufactured. MK does not hold itself responsible if the Self-Test Loop yields a
measurement outside of the tolerance due to poor care or attention of the ExLRT.
Typical loop value
9.5mΩ (+/-0.5mΩ).
Navigate through the menus to the
measurement screen and take a
loop test.
Typical joint value
8mΩ (+/-0.5mΩ)
To take a high value joint test,
connect the joint probes to the outer
points.
Typical joint value
0.2mΩ (+/-0.1mΩ)
To take a low value joint test,
connect the joint probes to the inner
points.
