No.
Upper shut off limit
The following signals have to occur with a load resistor of 325 Ω (normal function of the unit):
240
The blue LED (signal lamp "power output") glows.
-
The red LED (signal lamp "resistance too low") is dark.
-
-
A high frequency continuous signal is audible.
The following signals have to occur with a load resistor of 450 Ω (unit does not shut off):
250
The blue LED (signal lamp "power output") glows.
-
The red LED (signal lamp "resistance too low") is dark.
-
-
A pulsed signal with a high audio frequency is audible (end of treatment).

5. High frequency leakage current (according to IEC 60601-2-2)
No.
Test equipment:
Test accessories: Power cord
270
Measurement of the high frequency leakage current according to 19.3.101 a) 3) (bipolar application) as
described in IEC 60601-2-2. The output being loaded and unloaded at rated load.
Connect the unit via the power cord with a rated supply voltage. Connect the footswitch with the unit.
Connect the load resistor (100 Ω) with the HF-output 1 and 2 and with the electrosurgical analyzer
280
according to the analyzer's instructions for use to measure high frequency leakage currents. Set the
power level of the unit to "25" and measure the following parameter:
Attention: Start measuring, if not already done, after setting the power level to "25"and make
sure to release the footswitch before starting with a new measurement.
High frequency leakage current of HF-output 1 at output load 100 Ω:
290
High frequency leakage current of HF-output 2 at output load 100 Ω:
300
Disconnect the load resistor (100 Ω) from the HF-output 1 and 2.
310
Connect the HF-output 1 and 2 with the electrosurgical analyzer according to the analyzer's instructions
320
for use to measure high frequency leakage currents. Set the power level of the unit to "25" and measure
the following parameter:
Attention: Start measuring, if not already done, after setting the power level to "25"and make
sure to release the footswitch before starting with a new measurement.
330
High frequency leakage current of HF-output 1 with open output:
340
High frequency leakage current of HF-output 2 with open output:
