YES NO YES
Measure resistance up to 10 times,
between Kelvin Cable and "DUT
CASE" lead. The
OFFSET calibration
is subtracted from all measurements.
For the first measurement, the Kelvin
Cable should be connected to an
equipotential (grounding) stud located
near the DUT, and the "DUT CASE"
lead connects to the DUT itself. For
subsequent measurements, the Kelvin
Cable may be re-attached at arbitrary
locations on the DUT to confirm
continuity of the ground between the
Kelvin Cable and "DUT CASE" lead.
Ground resistance test of permanently-
installed equipment, followed by
continuity test of grounded metal parts
on the equipment.
Example: test of X-RAY equipment.
YES YES YES
Measure resistance between Kelvin
Cable and the test receptacle of
ES601-US
, one time. After this
measurement, the user disconnects
the DUT line cord from
ES601-US
and connects the "DUT CASE" lead
to the DUT.
For measurement #2, 3, 4... , the
resistance between the Kelvin Cable
and "DUT CASE" lead is then
measured, with the
OFFSET
calibration being subtracted to obtain
the results. The Kelvin Cable and test
lead may be moved to arbitrary points
of attachment and up to 9 additional
resistance measurements are acquired.
These additional measurements
confirm continuity of the ground
between the Kelvin Cable and "DUT
CASE" lead.
Ground resistance test of cord-
connected equipment, followed by
continuity test of grounded metal parts
on the equipment.
Example: test of a hospital bed.
Only those combinations shown in the above table are permitted by ES601-US; other combinations of
settings are inhibited.
