5) If a reading of zero volts on one terminal, and
a reading of 100 ~ 120 VAC on the other
terminal is obtained, remove both probes from
the outlet.
6) Set the meter to the “OHMS/Rx1” scale. Place
one probe on the ground terminal, and the
other probe on the terminal that produced a
reading of zero volts. The reading should be
less than 1 ohm.
CAUTION!
If the reading is more than one ohm, then
the outlet is not adequately grounded.
7) If the above tests show the outlet is not prop-
erly grounded, the condition should be cor-
rected (per Article 250 of the National Electri-
cal Code) by a qualified electrician before the
system is connected.
4.20 Alternate or Additional Ground
4.21 If the “third wire” AC ground can not practi-
cally be improved or if extreme motor noise or
other disturbance causes system malfunction, or if
local area lightning storms exist, a separate direct
ground may be warranted.
4.22 Connect a separate earth ground from a cold
water pipe or earth grounding rod directly to the FG
screw terminal on the DK8/DK16 power supply.
See Figure 4-5 of Section 100-816-204 (for
STRATA DK8) or Figure 5-8 of Section 100-816-
205 (for STRATA DK16).
