TI-45N Operating Instruction Guide
6.0 O VERVIEW OF M ODES
The TI-45N has several modes which are used for operation and velocity adjustment as
described below. Each time the MODE key is pressed, the gauge will toggle from one
mode to the next as shown in the sequence below:
1. Turn gauge on, last velocity setting is shown
momentarily, followed by
2. Press MODE key. Resin Mode
(Do Not Use)
3. Press MODE key. Aluminum Mode. This
mode is used for measuring aluminum and
other fine metals (titanium, etc.). THIS
MODE SHOULD NOT BE USED FOR
STEEL. To set for aluminum see procedure
below
4. Press MODE key. Resin/Aluminum Mode
(Do Not Use)
5. Press MODE key . Display will read C then
5930. This is the Coarse Adjustment Mode
that has preset Acoustic velocities for other
materials. Pushing up and down arrows will
set other velocities.
6. Press MODE key. Display will read A then
5930. This is the Fine Adjustment Mode. It
should be used for adjusting a velocity by
single numbers. (Press and hold up or down
arrows for rapid movement of numbers.)

Flow of mode selection:
S to B1 measurement method
Standard Thickness value
Measurement Ex.: 5.00 mm
F/ H appears on the extreme
right in Free / Hold mode,
respectively.
Aluminum Thickness value followed by A
Measurement Ex.: 5.00 mm_A
F/H appears on the extreme
right in Free/Hold mode,
respectively.
TI-45N provides two measurement modes depending
upon the nature of the test material (Standard and
Aluminum mode), which can be easily switched by
MODE switch operation:
Pressing and holding the MODE switch for longer than two seconds always
toggles back and forth between the Free and Hold modes.
Free mode is the correct choice for almost all applications. Select the Hold
mode when readings fluxuate and stable measurement cannot be obtained.
