The INITIAL SET UP procedure is accessed by holding the CAL key down and pressing the ON/OFF key.
When this is done the T-Mike E will display the version code of the operating software contained in the
unit until the CAL key is released.
This information will be useful should the unit require service or
updated software is desired.
Upon release of the CAL key the SETUP procedure continues as follows:
2.
Backlight On/Off
When the CAL key is first released the T-Mike E will display the words ON or OFF to indicate the status of
the backlight. The backlight setting can be selected by pressing the UP or DOWN arrow key.
NOTE: It is recommended that the backlight be OFF when measurements are made in well-illuminated
areas, as this will greatly increase battery life.
3.
Metric/English Units
Press the CAL key a second time.
The T-Mike E will display the units in which it is set to measure thickness (IN or MM).
Press the UP or DOWN arrow keys to select the desired unit of measurement.
4.
Calibration Lock
Press the CAL key a third time.
The T-Mike E will display the status of the calibration lock function (CAL or LOC).
When Cal is displayed the velocity calibration function can be performed as described in the 4
th

section B, OPERATION. When LOC is displayed the calibration function is disabled. The velocity used in
measurement cannot be changed without entering this SETUP procedure again to change settings to
CAL.
It is recommended that the lock feature be used when supervising personnel wish to prevent unauthorized
change of the calibrated velocity.
Pressing the Cal key a final time completes the SETUP procedure and returns the T-Mike E to the
measurement mode.
