CALIBRATION
Calibration of the
A.T.S.
4000TS Tourniquet allows the output signal from the pressure transducers to be compared
against a calibrated pressure source. The difference between the known pressure and the pressure measured by
the transducers is recorded at each of fi ve set-points for cuffs (0 mmHg, 50 mmHg, 250 mmHg, 475 mmHg and
600 mmHg) and 5 set-points for the reservoir (0 mmHg, 50 mmHg, 250 mmHg, 475 mmHg, and 700 mmHg). These
calibration points are used to correct the signal from the pressure transducers during normal operation. The calibration
points and a checksum are stored in nonvolatile memory. It is recommended the
A.T.S.
4000TS Tourniquet be
calibrated at least once every 6 months or after any scheduled or unscheduled maintenance.
