Cooper Instruments & Systems M5-1000 High Capacity Digital Force Gage - Manual (Page 10)

CF 183 7 32-1113 REV 2 1010
Trigger Force
The minimum force required to start the averaging sequence. Toggle between
compression and tension directions by pressing the DIRECTION key. Initial
delay follows the trigger force.
After the parameters have been configured and the menu has been exited, press MODE until AVG is displayed.
Then press ZERO. Average mode is now armed, and the averaging sequence will commence when the trigger
force has occurred. The current status of the average sequence is displayed below the primary reading, as
follows:
Step Status Abbreviation
Description
1. TRIG WAIT The trigger force has not yet occurred
2 INIT DLY The initial delay is currently taking place.
3 AVERAGING The gauge is collecting readings. The status will be flashing until averaging
has been completed.
4 AVRG DONE Averaging has been completed. The average force is displayed in the
primary reading.
At the completion of the averaging sequence, the peak values are retained until ZERO is pressed.
Another averaging sequence may be started after ZERO has been pressed. To exit Average mode, press
MODE and select the desired measuring mode.
5.5 External Trigger (ET)
This mode of operation is useful for measuring electrical contact activation force as well as synchronization of
multiple instruments for a “snapshot” view of applied forces. It is possible to capture the reading with a normally
open contact (high to low transition of the trigger signal) or a normally closed contact (low to high transition).
Before the parameters of External Trigger Mode can be configured, it must be enabled. To do so, enter the main
menu, select External Trigger, scroll to one of the four available options and press ENTER. The options are as
follows:
Option Description
Momentary High Æ Low The display will freeze the captured reading until ZERO is pressed. Applies to a
high to low transition of the trigger signal.
Momentary Low Æ High The display will freeze the captured reading until ZERO is pressed. Applies to a
low to high transition of the trigger signal.
Maintained High The display will show the captured reading only for as long as a high signal is
maintained.
Maintained Low The display will show the captured reading only for as long as a low signal is
maintained.

After the selection has been made and the menu has been exited, press MODE until ET is displayed.
External Trigger mode is now armed. Refer to the pin diagram in the Communications section for connection
information.
To exit External Trigger mode, press MODE and select the desired measuring mode.
