CALIBRATION
The InSpec 9000-2005 is calibrated at the factory. This calibration should last several months
with normal use. The data on the setup card that was received with the unit transfers the
calibration information to the InSpec calibration database. However, the calibration of the unit
should be periodically verified.
CALIBRATION VERIFICATION
Calibration may be verified by using one of the test cards Supplied with the InSpec 9000-2005.
This may be done as follows:
1.
From the Main Screen select ‘Do_Not_Add’ from the list of keywords. It is important to
do this so that the database only contains data on your production cards.
2. Click on the read card button to read the test card.
3.
From the ISO Parameters bar chart screen, click on “Numerical”, then compare the
average amplitude, average bit size and start sentinel values, for all three tracks, from the
numerical screen to the values for on the Test Card Results form included with the test
cards. Check to see if the readings are within the measurement uncertainty found below.
Measurement uncertainty of the InSpec 9000 System: Average Amplitude +/-
15%; Average Bit Size +/- 2%; Start Sentinel +/- 0.007 inches. To maintain the
range of measurement uncertainty, the tester and the card must be clean. The
card must also be flat and within ISO size specifications. This product tests
Amplitude, Jitter, Start Sentinel, and Baseline Integrity. There are other
parameters that may influence read reliability. Before testing for limits, the
program removes 0.130 inch from each end of the data.
RE-CALIBRATION PROCEDURE
Following procedure should be used to obtain the required information to see if calibration is
required:
1.
From the Main Screen select ‘Do_Not_Add’ from the list of keywords. It is important to
do this so that the database only contains data on your production cards.
2.
Select one of the two test cards that were sent with the InSpec 9000-2005 to perform this
test. The card you select must be sent in with the printed results, so keep track of which
one you use. Click on the read card button to read the test card.
3.
From the ISO compliance overview chart screen, click on “Numerical Results” to obtain
the numerical screen, and then click on “Print”. If a printer is not available, the Average
