Output Power

1) Equipment Requirements:
a) Monopolar Footswitch
b) Bipolar Footswitch
c) Commercial ESU Tester (e.g. Fluke 454A
or equivalent) with non-inductive 50 load
for bipolar modes and a non-inductive
500 ohm load for monopolar modes.
Note: Micro Bipolar is particularly sensitive to
the load resistance. A 50 ohm load should be
used for checking power to obtain the best

4) Disconnect the ESU tester from the unit.
5) Use test leads to connect the ESU tester to
the Bipolar Accessory outputs.

2) Use test leads to connect the ESU tester to
the unit's return electrode output and the
footswitch controlled active output. Set the
Load resistance per mode as indicated in
Tables 4.1 and 4.2.
3) Perform the monopolar power tests indicated
in Tables 4.1 and 4.2. The acceptance range is
given in both Watts and Amps to accommo-
date available test equipment. It is not neces-
sary to test for both power and current.
