• After the test is complete, raise the cabinet top, and slide the metal
length standard to the right along the track to remove the length
standard. Lower the cabinet top to its original position.
If the standards measurement is within ±0.004 inches of the actual
standard value, the instrument returns to the LENGTH/STRENGTH
CALIBRATION MENU when you press: ENTER.
If the value is greater than ±0.004 inches of the actual value, a "Fail"
indication is displayed. The instrument adjusts the software and stores
the new data. The test must be repeated until the length standard value
is within ±0.004 inches of the actual standard length standard value,
which is indicated by a “Pass” on the screen.
CAUTION:
When the calibration procedure has been completed, manually
slide the length standard to the right and out of the comb track.
This is an important step!
Attention: If the instrument is not able to bring the
length standard calibration within tolerance after several
cycles (i.e., if there is a continuous Fail), reset the
instrument, and try the length standard procedure
again. REMOVE THE METAL LENGTH STANDARD FROM
THE COMB TRACK BEFORE RESETTING.
4.4.1 Length Standard Check
The Length Standard Check screen gives the repeatability of the length
standard value to the service technicians. This measures, but does not
change, the total travel. This screen should not be accessed or modified
by HVI Operators
