Olympus ESG-400 - Measurement of the Bipolar High Frequency Leakage Current under Loaded Condition

ESG-400
2-8-3 Measurement of the bipolar high frequency leakage current under loaded condition
CAUTION
A connection of a 4 mm plug to any
other receptacle except
the right-hand-side receptacle of
the MONOPOLAR 1 socket and
the MONOPOLAR 2 socket may destroy
the socket during activation.
Fig. 5.2.8 and Fig. 5.2.9 are showing an example how to set up the test to measure the bipolar high frequency
leakage current under loaded condition. The load resistor R
L
= 500 Ω (J005) is connected via the connection
cables (J007, banana) with both BIPOLAR receptacles. The high frequency leakage current is floating from
appropriate pole to the equipotential bonding port. It is measured via the electrosurgical analyzer via a
measuring resistance of 200 Ω. Fig. 5.2.8 shows the measurement from terminal 1; Fig. 5.2.9 shows the
measurement from terminal 2.
1) Assign the footswitch to the BIPOLAR socket and select the BipolarCut mode with effect 3. Set the power
level to 100. (Perform the setting according to the instruction for use.)
2) Set up the measurement according to Fig. 5.2.8 (Measuring of the high frequency leakage current under
loaded condition at terminal 1.)
3) Activate the output power by pressing the corresponding footswitch pedal.
4) Verify the leakage current is ≤ 70 mA.
5) Set up the measurement according to Fig. 5.2.9 (Measuring of the high frequency leakage current under
loaded condition at terminal 2.)
6) Activate the output power by pressing the corresponding footswitch pedal.
7) Verify the leakage current is ≤ 70 mA.
8) Record the test results in the Inspection Card (see chapter 5-3).
