IMPORTANT NOTE:

Inherent in ultrasonic thickness measurement is the possibility that the
instrument will use the second rather than the first echo from the back
surface of the material being measured. This may result in a thickness
reading that is TWICE what it should be. Responsibility for proper use of
the instrument and recognition of this phenomenon rests solely with the
user of the instrument.

1.0 INTRODUCTION

The TI-25P is a precision Ultrasonic Micrometer. Based on the same operating
principles as SONAR, the TI-25P is capable of measuring the thickness of
various materials with accuracy as high as ± 0.001 inches, or ± 0.01 millimeters.
The principle advantage of ultrasonic measurement over traditional methods is
that ultrasonic measurements can be performed with access to only one side of
the material being measured.

3.0 OPERATING ELEMENTS

The TI-25P interacts with the operator through the membrane keypad and the
LCD display. The functions of the various keys on the keypad are detailed below,
followed by an explanation of the display and its various symbols.

3.1 The Keypad

This ON/OFF key is used to turn the TI-25P on and off. When the
gauge is turned ON, it will first perform a brief display test by illumi­nating all of the segments in the display. After one second, the gauge
will display the internal software version number. After displaying the
version number, the display will show "0.000" (or "0.00" if using metric
units), indicating the gauge is ready for use.

The TI-25P is turned OFF by pressing the ON/OFF key. The gauge has
a special memory that retains all of its settings even when the power is
off. The gauge also features an auto-powerdown mode designed to con­serve battery life. If the gauge is idle for 5 minutes, it will turn itself
off.

The PRB-0 key is used to “zero” the TI-25P in much the same way that
a mechanical micrometer is zeroed. If the gauge is not zeroed correctly,
all of the measurements that the gauge makes may be in error by some
fixed value. Refer to page 8 for an explanation of this important proce­dure.

The IN/MM key is used to switch back and forth between English and
Metric units. This key may be used at any time, whether the gauge is
displaying a thickness (IN or MM) or a velocity value (IN/µs or M/s)

The BACKLIGHT key switches the display backlight between three
available settings. OFF will be displayed when the backlight is switched
off. AUTO will be displayed when the backlight is set to automatic
mode, and ON will be displayed when the backlight is set to stay on. In
the AUTO setting, the backlight will illuminate when the TI-25P is
actually making a measurement.
