Chatillon DFS II - Contact Closure Setup

70 DF II Series User Manual
USING CONTACT CLOSURE (DFS II only)
The DFS II Series digital force gauge can be used
to identify two types of contact closure events:
n Break (Open) Connection
n Make (Closed) Connection
The DFS II Series digital gauge will freeze its
display at the force that was required to sense an
event change in a switch operation.
BREAK (OPEN) CONNECTION
The Break or Open Connection switch sensor
operates when the gauge has been setup to look
for an external signal change from 1-0 (Low).
The gauge setup option is called OPEN.
The DFS II will measure the force being applied to
a switch and will display the peak force that caused
the switch to “Open” or “break”. If the “Pass-Fail”
option is used, the gauge will also display whether
or not the force requirement was met and indicate
either a “Pass” or “Fail” label with the displayed
result.
MAKE (CLOSE) CONNECTION
The Make or Close Connection switch sensor
operates when the gauge has been setup to look
for an external signal change from 0-1 (High).
The gauge setup option is called CLOSE.
The DFS II will measure the force being applied to
a switch and will display the peak force that caused
the switch to “Close” or “make”. If the “Pass-Fail”
option is used, the gauge will also display whether
or not the force requirement was met and indicate
either a “Pass” or “Fail” label with the displayed
result.
