Set Testing Area
It is important that you set the TESTING AREA func-
tion on the Main Panel properly so that the automatic
overload detection circuit will stop a test if the load cell
is overranged. If pneumatic grips are being used with an
optional Air Kit, or cycling is to be done using the Lim-
its Section of the panel, it is essential to set the TEST-
ING AREA properly. The default state for the
TESTING AREA function is BELOW XHEAD.
Caution
Ensure that the TESTING AREA
function is properly set before start-
ing a test. If it is not and a load over-
range condition is detected, the
LOAD fault indicator flashes but the
crosshead does not stop, and dam-
age to the load cell could occur.
For normal operation, set the TESTING AREA function
to BELOW XHEAD. This applies to compression load
cells also.
The TESTING AREA function should be changed for
one of the following two conditions only:
(a) The sign of the output signal of the installed load cell
is positive (+) for compression (applies to 2511-200
Series compression cells only.)
