Note
If the test environment changes, for instance if there is an increase in humidity or if you are going to test at a
different altitude, make a probe check to verify that the system measures correctly.
1. Use a new probe tip, or make sure that the probe tip has been cleaned and dis-
infected, before you place it in the test cavity. This is to make sure that the
probe tip does not influence the probe test, and that the test cavity is not con-
taminated.
2. Insert the probe tip without eartip in the 2 cc test cavity.
3. Select the probe check function:

start the check.
The probe is checked for occlusion and leakage. If the probe check result shows
a value of 1.9 - 2.1 mmho/cc/ml at 226 Hz, the probe is OK. If not, we recom-
mend that you make an admittance calibration.
Additional probe admittance checks can be performed. See the MADSEN
Zodiac Reference Manual. 
If there is a probe error
In case of a probe error, the probe may be occluded or faulty.
If the probe is occluded, clean or replace the probe tip.
If the probe is faulty, contact an authorized service department for repair.
