58 Maintenance and troubleshooting Welch Allyn MicroTymp3 portable tympanometric instrument
1. Test Pattern - The test pattern is used to confirm that the print head is functioning
properly. If any of the print head elements are not functioning, a white line will appear
vertically down the printout. A defect in the paper may also cause white lines or light
printing. Repeat the test pattern to confirm any suspected printing problems. If paper
advances but nothing prints out, check to be sure the paper is inserted properly (see
page 52).
2. Software Version - The test pattern also includes the software version for the Printer/
Charger.
3. Normative Data Reference - The test pattern is followed by normative data for
tympanometric characteristics for both the MicroTymp2 and MicroTymp3 Handle. This
is provided along with the test pattern for the convenience of the user, not specifically
as a functional check.
