• Adjustable crosshead has been jammed into the table and will not move.
It is possible to overload the crosshead motor. If it is overloaded, oil is
relieved back to the reservoir. Damage to load cell, fixtures, etc. could
result.
If a specimen is gripped or the indicated
load is more than 1% of frame capacity,
contact your local Instron Services
department as directed on page 13.
If there is no specimen gripped and
indicated load is less than 1% of frame
capacity:
1. Turn the system disconnect switch
to OFF ( O ).
2. Watch movement of the
compression table. If the
compression table moves away
from the crosshead as the piston
falls, continue with next step. If the
compression table does not move
away from the crosshead as the
piston falls, contact your local
Instron Services department as
directed on page 13.
3. Inspect the frame and any installed
fixtures for obvious damage.
4. Spot check load accuracy of the
system, contact your local Instron
Services department as directed on
page 13.
