2) One at a time, connect this series combination to each RF output terminal indicated in Table 4.5 and
activate the unit using the corresponding command. Confirm that no meter readings exceed the specified
maximum.
Table 4.5 Allowable RF Leakage Current - Inactive Monopolar Outputs
MEASURED TERMINAL ACTIVATED ACCESSORY MODE RF LEAKAGE (Ma)
Combination Monopolar Active Hand Controlled Standard Coag < 50
Combination Monopolar Active Bipolar Footswitched Macro < 20
Hand Controlled Active Combination Monopolar Standard Coag < 50
Hand Controlled Active Bipolar Footswitched Macro < 20
Bipolar Left Right Hand Controlled Standard Coag < 48
Finally, RF leakage should be measured between
the inactive bipolar outputs while a monopolar
accessory is activated. Do the following:
1) Set the unit for full power for the bipolar
mode noted in Table 4.6. Connect ESU tester
Table 4.6 Allowable RF Leakage Current - Inactive Bipolar Outputs
MEASURED TERMINAL ACTIVATED ACCESSORY MODE RF LEAKAGE (Ma)
Bipolar Right to Left Hand Controlled Standard Coag < 48
according to manufacturer’s instructions -OR
the 200-ohm non-inductive resistor in series
with the 250 mA RF ammeter between the
two bipolar output connections.
2) Activate and verify the limit in Table 4.6.

CAUTION: To prevent RF current from destroy-
ing the test equipment and/or affecting leakage
readings, set all power settings to zero.
WARNING: ELECTROCUTION HAZARD.
USE OF AN ISOLATED MAINS POWER
SOURCE IS RECOMMENDED WHEN
OPENING THE MAINS GROUND
DURING THE FOLLOWING SAFETY
TESTS.
Circuit ground and Neutral (Low Mains) must be
connected together for Mains leakage testing.
Equipment:
These tests are performed most conveniently using
any good quality biomedical electrical safety tester.
Procedure:
1) Connect the electrical safety analyzer to make
the measurements indicated in Table 4.7.
2) Mode: Measure leakage for Bipolar to Neutral
and Chassis to Neutral.
