Versitron Operation Manual
5.3
All Manual or Automatic Bench Stands
Your tester should be installed before proceeding and the test head set up for
operation with a diamond indenter in place (See Section 3.0)
1.
Check to make sure a diamond indenter is installed in the test head. If not, refer
to the next section for installing indenters.
Be sure the indenter shroud is
installed.
2.
Put the two inch flat anvil in the elevating screw and place a Rockwell C test
block on the anvil (Or Rockwell N block if using a superficial head).
3. Raise the
elevating screw by turning the height adjuster until the test specimen
touches the clamping shield (if the clamping shield is being used) or until it is
within 1/16” of the indenter (the test piece should not touch the indenter). If the
elevating screw will not raise high enough when using a AT130T stand, loosen
the lock knob at the right rear of the stand and turn the height adjustment knob at
the top-back of the stand to lower the test head position.
4. Turn the power switch on at the back of the test head. The display will initiate
with the “Splash Screen”.
Allow 10 minutes for the electronics to equilibrate
.
5. After the “Splash Screen” flashes the Ametek and Newage logos, the display
changes to show the “Test Screen”.
6. For manually operated testers, pull the load lever forward until it stops. Hold the
lever down until time reaches zero, then release to remove the load.
7. For automatic machines simply press the remote foot pedal. The display will
show the Rockwell test value.
