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 torque has been reduced to a
safe level).
Five operating modes are possible with the TT02 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 torque 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, for counter-clockwise readings.
5.4 First / Second Peak (2PK)
Displays first and second peaks for the same measurement direction. This function is used to identify the
true peak before tool rotation reaches a hard stop, causing an artificial spike in torque. This mode will only
appear if enabled in the First / Second Peak menu.
5.5 Break Detection (BRK)
Arms the tester for automatic data output, automatic zero, and/or automatic data storage upon tool slip or
click, as configured in the Break Detection menu. This mode will only appear if enabled in the Break
Detection menu.
