Quickcheck - Welch Allyn MicroTymp Operating Instructions Manual

Quick Check
The QUICK CHECK provides a complete functional test of the
MicroTymp.
The QUICK CHECK should be used at least once per month and
whenever there is any question regarding MicroTymp operation. This
provides rapid assurance that the MicroTymp is working properly.
To use the QUICK CHECK:
1. Test .5cc QUICK CHECK cavity as if it were an ear, holding unit
carefully to prevent movement. Printer should not be running during
the test, and stand should be located on a flat vibration-free surface.
Excess noise or vibration during test will cause inaccurate
results.
2. Print results for that tracing only (other memory should be empty).
3. Insert results in QUICK CHECK window.
4. Align baseline and +200 Vea axis of the printout with window.
5. The printed value of +200 Vea should fall within the 0.5~~ box
on the window. If the printout is outside the box, return
MicroTymp for recalibration.
Check Window
6. Repeat steps 1-5
NOTE: While QUlCK CHECK provides a functional test, it does not
replace recalibration.
As the altitude above sea /eve/ increases, the admittance of an air
filled cavity also increases. Therefore, at elevations above 2,600
feet, results using QUICK CHECK will change as follows:
Elevation
2,600 ft. (792 m)
5,000 ft. (1,525 m)
