General Warnings
Safety Warnings 
Operators should take care to operate this machine under the maximum 
load restrictions. The machine is programmed at the factory to provide 
safety shutdown if the upper or lower maximum travel is exceeded as well 
as if the upper instrument calibration is exceeded.
Electrical Warnings 
Typically, there is no reason for the operator to open the machine. However, 
if the customer’s engineers attempt to change settings to the circuit board 
connected to the back panel, the machine must always be unplugged before 
this operation. Unplugging the internal connection to 
the back panel circuit board while the machine is under power will result 
in permanent damage to the circuit board.
