Instrument recognition APC socket
Testing and measuring equipment
Instrument recognition via
resistance
Test setup
• The test specimen is connected to the power supply via a VIO electro-
surgical unit.
• The APC measuring cable is connected to an APC socket on the test
specimen.
• The red cable of the APC measuring cable is connected to the APC test
box (red socket instrument detection).
Test procedure
1st test step 1. Insert the blue connector of the APC measuring cable into the 10 Ohm
socket of the APC test box. The test specimen must detect that an
instrument has been connected and display a corresponding advisory
message.
2. Disconnect the resistance. The test specimen must detect and display
instrument removal.
2nd test step 1. Insert the blue connector of the APC measuring line into the 90 Ohm
socket of the APC test box. The test specimen must detect that an
instrument has been connected and display a corresponding advisory
message.
2. Disconnect the resistance. The test specimen must detect and display
instrument removal.
Instrument recognition
via EEPROM
Test setup
• The test specimen is connected to the power supply via a VIO electro-
surgical unit.
Test procedure
1. Connect VIO APC handpiece to an APC socket on the test specimen.
The test specimen must indicate instrument recognition with a mes-
sage. The setting on the VIO HF surgical unit must switch to APC
socket.
2. Remove VIO APC handpiece. The test specimen must recognize and
indicate removal of the instrument.
