8.2.7 Patient leakage current tests – overview
The following table specifies the parameter modules and the related patient connectors to be
tested in the
current
Use the safety test body kit, P/N M1155870 (or equivalent), to perform patient leakage current
tests. This safety test body kit contains various patient connectors where all pins are shorted
out together. For information on which test body to use for each patient connector, refer to the
service instructions included in the safety test body kit.
NOTE: If not otherwise stated in the table below, each test body is connected directly to the
specified connector in the patient module.

1. Connect the BISx Digital Signal Processing Unit with the Patient
Interface Cable (PIC+) to the E-BIS module.
2. Connect the specified test body to the PIC+ cable.
NOTE: The patient isolation is in the BISx Digital Signal Processing
Unit , not in the E-BIS module.
1. Connect an Entropy sensor cable to the module.
2. Connect the specified test body to the Entropy sensor cable.
1. Disconnect the N-EEG headbox from the E-EEG module.
2. Connect the test body directly to the E-EEG module.
