THE DEVICE VERIFICATION PROCEDURE
The verification operation is intended to determine if the internal force
measurement system is within specification. It is NOT a calibration
procedure.
1. Allow the tribometer to acclimate to the ambient
temperature of the test area.
2. Press any one of the six panel switches momentarily to
power up the device.
3. Place the device onto a very stable and level surface.
4. Stand the device on the aft (printer) end, and then carefully
insert the verification mass into the sensor port.
5. The VERIFY option indicator will appear (Fig.2, lower left
screen).
6. Press the switch adjacent to “VERIFY”. NOTE: Near the
screen bottom, there are two tilt indicators. These should
indicate 90 +/- 2 degrees and 0 +/- 2 degrees in order for
the device to verify accurately, otherwise a more level
surface must be found.
7. Press the “START” switch; the device will now begin the
verification process. Be certain that the device remains
level and stable during this process, otherwise the device
may fail. Once the device has completed the verification
process, it will indicate a “PASS” or a “FAIL” status. You
may press the “PRINT” or “DONE” switch at this time. If the
device fails, the procedure may be repeated after re-
checking the level or moving to a more level location. The
mass may require removing and replacing or be checked
for free movement. If the device passes verification, the
force measurement system is within factory specifications.
8. Wait several seconds before removing the verification
mass so the device can reset.
9. If the device cannot be verified because of an internal fault,
it must be returned to Regan Scientific Instruments for
service.
