Section 1
Introduction
The LCT-601 is designed tofacilitate connections as noted in NFPA 99 so tests by manufacturers
and users can be made in a fast and repeatable, safe way. Operation Instructions are broken up so
manufacturers and end users can go directly to their battery of tests.
This Section contains a Checkout Procedure which can be used to check proper switch operation.
Section 2 describes use of the LCT-601 by Manufacturers, to verify compliance with the
requirements of NFPA 99, Section 10-2.13.
Section 3 describes use of the LCT-601 for those requirements for Installed Equipment, both cord
connected and permanently connected, in accordance with NFPA 99, Section 8.4.1.3.
Section 5 contains annual calibration instructions which can also be used for impromptu checks of
proper operation of the LCT-601.
Checkout Procedure
In order to verify proper operation of the switches on the LCT-601, this procedure may be used on a periodic

switch) to the CHASSIS MEAS. POINT
(left) position.
3. Set the EARTH switch (second switch
from the top) to the EARTH-CHASSIS
CONNECTED (left) position.
4. 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.
5. Flex the cord at its connection to its
attachment plug cap and note the
reading on the resistance meter.
6. Flex the cord at its connection to the
EUT and note the reading on the meter.

and exposed grounded metal on the
EUT.
9. Regarding the power switch of the EUT,
the test is to be conducted with the EUT
power switch in both the ON and OFF
positions.
10. Read the current meter for both
conditions above. A passing result is <
300uA (<300uV on the meter connected
to the LCT-601) for cord connected
products. Higher leakage currents are
allowed under special conditions; see
NFPA 99 Para. 8.4.1.3.5.2 for further
details.
11. See Figure 10 and Table 10 for a Test
Setup synopsis. This section is based
on NFPA 99 Fig. 8.4.1.3.5.5, see below.

Equipment Lead to Ground –
Nonisolated Input Test
1. Connect the LCT-601 to the EUT using
the female attachment plug cap pigtail.
2. Connect the LCT-601 to mains power
using the male attachment plug cap
pigtail.
3. Set the MEAS POINT Switch to the
CHASSIS MEAS POINT (left) position.
4. Regarding the EARTH switch (second
switch from the top); the test is to be
conducted with the EARTH switch in
both positions.
5. Set the NEUTRAL switch (third switch
from the top) to the NEUTRAL
CONNECTED position.
6. Set the POLARITY switch to the
NORMAL position.
7. Set the power switch of the EUT to the
ON position.
8. Connect a calibrated voltage meter
across the RED and GREEN LEAKAGE
banana plugs on the LCT-601. Set it to
read ~100uV.
9. Connect all patient-connected leads
together, connect them to the RED
LEAKAGE banana plug of the LCT-601
and conduct measurements for both test
conditions. For this test, switch the
EUT to the output condition that results
in the highest leakage output.
10. Read the current meter for both
conditions noted above. A passing
result is <100uA (<100uV on the meter
connected to the LCT-601) for any
condition.
11. See Figure 11 and Table 11 for a Test
Setup synopsis. This section is based

1. Connect the LCT-601 to the EUT using
the female attachment plug cap pigtail.
2. Connect the LCT-601 to mains power
using the male attachment plug cap
pigtail.
3. Set the MEAS POINT Switch to the
CHASSIS MEAS POINT (left) position.
4. Regarding the EARTH switch (second

5. Set the NEUTRAL switch (third switch
from the top) to the NEUTRAL

7. Set the power switch of the EUT to the
ON position.
8. Connect a calibrated voltage meter
across the RED and GREEN LEAKAGE
banana plugs on the LCT-601. Set it to
read ~10uV.
9. Connect the RED LEAKAGE banana
plug of the LCT-601 to each patient-
connected lead in turn and conduct
measurements for both test conditions.
Each patient-connected lead is to be
energized by properly switching the
EUT.
10. Read the current meter for the eight
conditions noted above and for each
patient-connected output. A passing
result is <10uA (<10uV on the meter
connected to the LCT-601) with the
GROUND switch in the CONNECTED
position, and <50uA (<50uV on the
meter connected to the LCT-601) with
the GROUND switch in the OPEN
position, for any condition.
