6. If the BIS and NMT modules are configured, perform the following patient auxiliary current
tests between each electrode and the others by turns:
 Normal polarity;
 Reverse polarity;
 Normal polarity with open neutral;
 Reverse polarity with open neutral;
 Normal polarity with open earth;
 Reverse polarity with open earth;
7. Verify that the maximum leakage current does not exceed 100 μA (0.1 mA) in the first two
tests. While for the last two tests, verify that the maximum leakage current does not exceed
500 μA (0.5 mA).
NOTE
 Ensure the safety analyzer is authorized by certificate organizations (UL, CSA,
AAMI, etc.). Follow the instructions of the analyzer manufacturer. Fluke ESA620
is used as an example.
