the unlikely event that a mercury spill should occur. Please read this
manual thoroughly and retain for future reference.
PREVENTIVE MAINTENANCE
Because the mercury units do not rely on moving parts such as metal
bellows, diaphragms, gears, or other sources of mechanical wear,
only an occasional inspection of the instrument is recommended.
A regular program of preventive maintenance will extend the life of
your sphygmomanometer. The program should include the following
simple inspection steps:
1. The mercury level in the graduated plastic tube should be at
the “0” calibration mark with the inflation system disconnected
and the mercury unit in a vertical position.
Note:
If the mercury level is below “0”, readings over the entire scale
will vary only the difference between the mercury level and the “0” cal-
ibration.
2. Airflow should be tested by partially inflating the instrument to
observe the rising column of mercury, and then slowly deflating -
stopping the column at several points - to observe the falling col-
umn.
The diaphragm filter should be replaced if the mercury does not
rise easily in the tube, or if the mercury column bounces notice-
ably.
