Press the Test button
IMPEDANCE CHECK
An impedance check will begin. Impedances are indicated by the green/amber dots on the montage picture
as well as in numerical format on the screen.
RESULTS
PASS result
When the pass criteria for the test
is reached, a is displayed in
green above the measurement,
indicating the test has PASSED.
D-0118113-C – 2019/03
When a dot is amber, it means the impedance is poor (> 50kΩ) for the
indicated electrode. Check that the surface electrode and cables are
connected correctly. It may be necessary to re-clean the skin or use a
conductive gel with the surface electrodes to achieve an acceptable
impedance. Testing cannot begin until impedance indictors are green
(< 50kΩ).
REFER result
When the pass criteria for the test
is not reached
measurement time,
in amber above the measurement,
indicating the test is a REFER.
INCOMPLETE result
If the test is stopped before a
within the PASS or REFER is generated by
is displayed the system,
the measurement indicating that
the test is INCOMPLETE.
