•
Hot to neutral,
•
Neutral to ground, and
•
Hot to ground.
Power Cord Resistance
After taking measurements of line voltage, the autosequence moves to the
power cord resistance measurement. The medTester offers you the option of
skipping the test. You could skip a resistance measurement, for example, with
double-insulated equipment having no exposed metal surfaces. If you choose
to skip this test, it is recorded as being skipped. To skip the measurement,
from the menu select:
SKIP
F4
You can proceed with the resistance test, but first notice the displayed reading
and
CURRENT SOURCE annunciator. If any of the following appear on the
medTester display, it means a condition exists that prohibits an accurate
measurement:
•
# (pound) sign—Indicates an out-of-limit condition based upon the
resistance limit set for the autosequence you are running. Limits are
programmable.
•
x.xxx—Indicates that a current source is not connected.
•
Flashing reading—Indicates that the displayed reading is out of
range, that is >2 ohms.
•
CURRENT SOURCE annunciator not lit—Indicates lack of a good
connection.
Correct the cause of the condition before continuing. For example, reconnect
the Kelvin cable to an exposed grounded surface on the EUT. If none of
these conditions exist and a measurement appears in the display, press:
READY
