MiniMax Bolt Tension Monitor
4.7 GATES – Menu
POLARITY: The MiniMax operates on a zero crossing detection principal. This
feature toggles which stroke of the cycle the crossing detection uses, either positive
or negative. Refer to page 156 for further info.
GATE: Gates allow the user to view a specific measurement range, or sections of
the waveform, and ignore others. The Gate1 feature adjusts the start of the gate,
according to time/distance. Gate 1 can be used in all pulse-echo and echo-echo
measurement modes. Refer to page 135 for further info.
THRESHOLD1: Enables the user to set the sensitivity level of Gate1. The amplitude
of the signal must reach or exceed the threshold level before a measurement is
detected. Refer to page 135 for further info.
4.8 AUTO – Menu
AUTO SET: Automatically locates the detection point if the measurement is out of the
viewable display area. Used when measuring reference lengths only. Refer to
section 12.9 for further info.
APPROX LEN: In order for the user to use the Auto Set feature, an approximate
length of the fastener must be entered. The approximate length gives the MiniMax
some idea of where to turn on the receiver and look for the detection, or end of the
bolt. This sub menu item enables the user to edit the length at anytime. Refer to
section 12.9 for further info.
