User Defined Function Keys 13
3.5 Peak Hold
Peak Hold automatically updates the display when a higher peak weight reading is
established.
The Peak Hold function uses a high speed mode of the A/D converter (220 samples)
allowing it to capture transient loads at a far higher rate than typical Dynamometers.
Peak hold is cleared and re-enabled with the Fx-Peak Hold Key. When a new peak is
detected, the Fx LED will flash three times. The accuracy of the system in Peak Hold
mode is slightly reduced to .2% of Capacity + 5d. The Filter setting is turned off while
in Peak Hold mode to ensure the fastest acquisition rate.
Example
The Peak Hold function is useful in “Dynamic” and “Fall” tests. Common tests
include “Overall Breaking Strain” (OB€), Breaking Force, and Cycled Breaking
Strain.
3.5.1 Capture Peak Force
1) Program a function key to Peak
Hold (P-Hld)
In this example we’ll use F1 for Peak
Hold.
2) Prepare the test stand and test
sample.
3) Press ZERO to zero out any
residual strain on the link.
4) Press F1 PkHold Confirm that
the “Pk” annunciator is on.
A small jump in the reading may occur
depending on the stability of your test
device.
5) Apply the test force. The F1 LED
will blink three times when a
new peak value ID is detected.
6) When the force is removed,
the Peak value can be recorded.
7) To run a new test, press
F1 PkHold to clear the Peak
Value. Confirm the “Pk”
annunciator is off. Then repeat
steps 3-6.
