Peak Blanking (1-3)
PEAK BLANKING
determines the minimum threshold at which a torque peak is captured. It is entered as a
percentage of the full scale value of the transducer which is connected to the ATDA and can be displayed in values
from 2 – 50% of transducer full scale. Accurately setting the PEAK BLANKING value can help prevent invalid torque
readings and can enable the user to avoid taking readings related to high prevailing torque in an application.
Setting the Peak Blanking Value
1. From the main display press
MENU
2. Press the
Right Selection
button to select PEAK OPTIONS MENU
3. Use the
SELECTION ARROW
buttons to select PEAK BLANKING
4. Use the
Left Selection button
to decrease the PEAK BLANKING value. Use the
Right Selection
button to
increase the PEAK BLANKING value. Either button, when continuously pressed, will advance the value in a
loop.
5. When the desired value is selected, press
ENTER
to save and exit.
Sign Lock (1-4)
The
SIGN LOCK
feature allows the user to select the rotation direction in which a torque peak will be captured. With
SIGN LOCK on, the initial direction is set as the default direction; a negative torque value indicates a reading taken in
the counter-clockwise direction and a positive reading indicates a reading taken in the clockwise direction. Any
readings taken in the non-selected direction will be measured, but not captured / displayed as a peak value.
With SIGN LOCK turned off, peak values in both the clockwise and counter-clockwise directions will be captured and
displayed.
Since most torque rundowns are conducted and readings are taken in the clockwise direction, the user may find it
beneficial to turn this feature on.
Turning Sign Lock On / Off
1. From the main display press
MENU
2. Press the
Right Selection
button to select PEAK OPTIONS MENU
3. Use the
Selection Arrow
buttons to select
SIGN LOCK
4. Use the
Left Selection button
to toggle
SIGN LOCK
on or off.
5. When the desired value is selected, press
ENTER
to save and exit.
Resetting Sign Lock
If
SIGN LOCK
is on and needs to be reset, either turn the ATDA off or press the CLEAR/ZERO button.
