5) Since the System 5000™ monopolar active
outputs are disconnected by relays when the
unit is not activated, active-to-neutral leakage
tests must be performed with the unit acti-
vated in order to be valid.
6) With all power controls set to zero, measure
the leakage current as in step 1 from each of
the three active output terminals to neutral;
see Table 4.8; while that output is activated
in Cut by the appropriate footswitch or hand
control jumper. Hand control cut activations
are accomplished by connecting a jumper
between the two outer jacks of where the
handcontrol accessory is plugged into the
unit.

4.6.6 Automatic Return Monitor (A.R.M.™)
Check
A.R.M.™ has two specific ranges that will be
tested initially and then the circuit will be tested
to verify that the circuit measures dissipative elec-
trode resistance correctly. For this testing, only a
Decade Resistance Box (DRB) and a dispersive
electrode cable adapter are required. Connect the
DRB to the Dispersive Electrode Receptacle using
the dispersive electrode cable adapter.
A.R.M.™ may be reset by disconnecting the
dispersive electrode connector or adjusting the
DRB above 10K Ohms until the Single and Dual
Dispersive Electrode Status/Alarm Indicators flash
red in alternating fashion. Allow approximately
two seconds after the DRB is changed before
proceeding to the next step in the procedure.
A.R.M.™ indicators not mentioned in the proce-
dure must be off for each test.
1) Dual Electrode Alarm Limit: Set the DRB to
158 Ohms, then connect it to the Dispersive
Electrode Receptacle and verify that the
Single and Dual Dispersive Electrode Status/
Alarm Indicators flash red in alternating fash-
ion.
2) Dual Electrode Upper Limit: Set DRB to
140 Ohms and verify that the Dual Dispersive
Electrode Status/Alarm Indicator is flashing
Green and a single bar in the Bargraph is illu-
minated.
3) Dual Electrode Lower Limit: Set the DRB
to 15 Ohms and verify the Dual Dispersive
Electrode Status/Alarm Indicator is flashing
Green and eight bars in the Bargraph are illu-
minated.
4) Single Electrode Upper Limit: Set the DRB
to 7 Ohms, then reset A.R.M.™ and verify
the Single Dispersive Electrode Status/Alarm
Indicator is Green and not flashing.
