When you turn off the T-Mike Programmable, it will display the EPROM software version. When you
turn on the T-Mike Programmable, it will momentarily display the calibrated sound velocity. Test the T-
Mike Programmable on a material sample to verify that it reads the correct thickness.

T-MIKE BASIC
1. Configuration and Calibration
The T-Mike Basic has five operator selectable materials (steel, aluminum, stainless steel, cast iron, and
plexiglass) with is preset sound velocities. One custom material ca be programmed by connecting the T-
Mike B to an IBM compatible computer running special software, or from a T-Mike E. In either case, a
special cable is required.
2. Material Selection
First follow the above PROBE ZERO procedure to calibrate the delay of the ultrasonic transducer being
used.
MAT
Press the MAT key to select the material being tested.
Select the material by using the UP and DOWN arrows. Press the MAT key a second time to
store the velocity for the selected material.
Some materials may exhibit sound velocity variations which can cause errors in measurement. Be sure to
check a representative group of samples to determine if such variation is present.
3. Initial Setup
In order to change the settings of the T-Mike B, the instrument must be powered on in the Initial Setup
mode. The settings, which may be changed, are the units of measure and the backlight. This procedure
is defined in the INITIAL SETUP ("A" – page 1). Use the MAT key on the T-Mike B as CAL key
referenced in the procedure.
4. To Program from a T-Mike E
Set the T-Mike E in the desired mode by holding down the CAL key while turning on the power. Now
calibrate the sound velocity of the T-Mike E to the desired sound velocity. Turn off both gauges. Connect
the special cable between the two data/charger ports. Turn on the T-Mike E; press the CAL key twice and
