Pinch Load - Ametek Chatillon CS1100 User Manual

Enter the required value then press on the ENTER button. To change the unit (which will be
initially set to the "Default" Force unit), press the button to the right of the Grip Protection
entry area to cycle through the available units.
Please note that the grip protection value is only updated after exiting the
configuration screens, i.e. when the Home screen is re-displayed.
If any numeric field needs to be edited after an initial value has been entered, press
two times (double tap) on the "GRIP PROTECTION" entry area.
To enter a barcode into the required field, press on the edit box field above the
keyboard to enable the field then scan the barcode.

4.6 PINCH LOAD

The pinch load setting stops the Force Tester if an excessive compressive force is applied
when the Force Tester is being jogged (driven using the positioning buttons). This is to
protect the operator and should be set to a reasonably low value, e.g. 50N or 10lbf. Note
that the pinch load feature uses the "displayed" load value so the Force Tester must be re-
zeroed whenever grips are changed or removed before trying to re-position the crosshead.
The maximum pinch load that can be set is 200N or 40lbf. However, AMETEK recommends
that the pinch load is not set above 50N or 10lbf.
Assume that the pinch load is set to 10lbf and a compression plate weighing 15lb is fitted to
the bottom of the load cell. If the compression plate is removed from the load cell, the Force
Tester will display a compressive load of 15lbf. This exceeds the pinch load of 10lbf so the
crosshead cannot be driven downwards. Therefore, the Force Tester must be re-zeroed
before the crosshead can be driven downwards as normal.
To change the Pinch Load value, press on the "PINCH LOAD" entry area to display a
numerical keypad, enter the required value then press on the ENTER button. To change the
unit (which will be initially set to the "Default" Force unit), press the button to the right of the
Pinch Load entry area to cycle through the available units.
Please note that the pinch load value is only updated after exiting the configuration
screens, i.e. when the Home screen is re-displayed.
