Dear Doctor:
We checked the calibration of your Field Analyzer, serial number today
and found that it was reading dB too high / low (circle one). The instrument has
now been recalibrated.
Please keep this calibration shift in mind when comparing future results against previous field. If it was
reading too high, future tests of stable patients will tend to show an artifactual loss in threshold
sensitivity in the amount shown above. If it was reading too low, future tests will tend to show an
artifactual improvement.
We recommend yearly preventative maintenance and calibration checks for your Field Analyzer.
Inquire about our service contracts which include a yearly preventative maintenance visit.
If you have any questions, please contact Carl Zeiss Meditec at 800-858-1508 and ask to have your
area’s Regional Service Manager give you a call.
Sincerely,
Carl Zeiss Meditec Field Service Engineer
