6.2.1 Ground Continuity
6.2.1.1 Unplug the AC power cord for all devices mounted to the
machine that may provide an alternate path to earth ground,
such as a Desflurane vaporizer.
6.2.1.2 Unplug the machine’s AC power cord and plug the power cord
of the safety analyzer into this AC receptacle.
NOTE: Do not plug the safety analyzer power cord into a line
isolation monitor circuit, as inaccurate readings may
occur.
NOTE: The BIOTECH 501 PRO will automatically test the
source outlet for open ground (or ground resistance of
31 Ohms or higher), reverse polarity, open neutral and
open line. (The latter two conditions will prevent the
analyzer from powering up.)
6.2.1.3 Turn on the safety analyzer and set it’s function switch to the
GROUND WIRE RESISTANCE position. Attach the test lead
to the red SINGLE LEAD connector of the analyzer. Connect
the other end of the red test lead to the AC receptacle ground
socket on the safety analyzer. Verify a displayed resistance of
0.00 ohms or, if necessary, press the CALIBRATE key on the
front panel of the analyzer to zero the device.
