Section 3
LCT-601 for End Users: NFPA 99, Section 8.4.1.3:
This section describes how to set up and use the
LCT-601 to aid in the testing to NFPA 99, Section
8.4.1.3: Testing Requirements-Fixed and Portable.
Exact setup instructions are included for each
test. These instructions are generic in nature and
must be checked for accuracy in actual use, and
may not reflect NFPA interpretations.
Paragraph 8.4.1.3.2: Grounding
Circuit Continuity Test
This test verifies that the grounding lead in
grounded equipment is properly connected to the
appliance.
9. Connect the LCT-601 to the EUT using
the female attachment plug cap pigtail.
It is not necessary to connect the LCT -
601 to line power to conduct this test.
10. Set the MEAS. POINT switch (top
switch) to the CHASSIS MEAS. POINT
(left) position.
11. Set the EARTH switch (second switch
from the top) to the EARTH-CHASSIS
CONNECTED (left) position.
12. Using a calibrated resistance meter,
connect one lead to the GREEN banana
jack on the LCT-601. Connect the other
lead to exposed dead metal or the
chassis of the EUT.
13. Flex the cord at its connection to its
attachment plug cap and note the
reading on the resistance meter.
14. Flex the cord at its connection to the
EUT and note the reading on the meter.
15. If the resistance of both tests is less
than 0.5 ohm, the result is a PASS. If the
resistance of either test is 0.5 ohm or
greater, the result is a FAIL.
16. See Test Setup in Fig. 1 and Table 1.
