5 OPERATING MODES
Caution!
In any operating mode, if the capacity of the instrument has been exceeded by more than 110%,
the display will show “OVER” to indicate an overload. A continuous audible tone will be sounded
(if beeps are enabled) until the MENU key has been pressed or the load has been reduced to a
safe level.
Three operating modes are possible with the TT05 torque tester. To cycle between the modes, press
MODE while in the home screen.
5.1 Real time (RT)
The primary reading corresponds to the live measured reading.
5.2 Peak Clockwise (PCW)
The primary reading corresponds to the peak clockwise reading observed. If the actual load decreases
from the peak value, the peak will still be retained in the primary reading area of the display. Pressing
ZERO will reset the value.
5.3 Peak Counter-clockwise (PCCW)
Same as above, but for counter-clockwise readings.
6 CHANGING THE UNITS
The TT05 can display five different measurement units. To change the unit, select Units from the menu.
The display will list the available units, as follows:
The tester will always power on with the unit selected in this sub-menu.
7 DIGITAL FILTERS
Digital filters are provided to help smooth out the readings in situations where there is mechanical
interference in the work area or test sample. These filters utilize the moving average technique in which
consecutive readings are pushed through a buffer and the displayed reading is the average of the buffer
contents. By varying the length of the buffer, a variable smoothing effect can be achieved. The selection
of 1 will disable the filter since the average of a single value is the value itself.
To access digital filter settings, select Filters from the menu. The display will appear as follows:
