Page 7: Important Notice
IMPORTANT NOTICE The following information must be read and understood by any user of a GE Inspection Technologies ultrasonic thickness gauge. Failure to follow these instructions can lead to errors in thickness measurements or other test results. Decisions based on erroneous results can, in turn, lead to property damage, personal injury or death. - Page 8 Behavior of the sound wave where two different materials are in contact Areas covered by the sound beam More specific information about operator training, qualification, certification and test specifications is available from various technical societies, industry groups, and government agencies. Testing Limitations In ultrasonic testing, information is obtained only from within the limits of the sound beam.
- Page 9 Calibration of Sound Velocity The principle of operation of an ultrasonic thickness gauge is that the instrument measures the time of flight of an ultrasonic pulse through the test piece and multiplies this time by the velocity of sound in the material. Thickness measuring error is minimized by ensuring that the sound velocity to which the instrument is calibrated is the sound velocity of the material being tested.
- Page 10 Transducer Selection The transducer used in testing must be in good condition without noticeable wear of the front surface. Badly worn transducers will have a reduced effective measuring range. The specified range of the transducer must include the complete range of thickness to be tested.

Page 11: Thoeory Of Operation
The time correction is accomplished automatically by performing a “PROBE” recognition operation. The means to perform this simple task is resident on the T-Mike ES and will be explained in detail later. SINGLE POINT VELOCITY CALIBRATION Upon recognition of the probe a calibration of the velocity of the material to be measured must be done. - Page 12 To maximize measurement accuracy select a calibration piece that has the same shape and approximate thickness as the work piece being measured. Re-calibrate the T-Mike ES when the temperature of the work piece changes 5 o C or more from the calibration piece.

Page 16: Initial Setup
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 ES will display the version code of the operating software contained in the unit until releasing the CAL key. - Page 17 METRIC/ENGLISH UNITS Press and release the CAL key again. The T-Mike ES will display the units in which it is set to measure thickness (IN or MM). Press any key to select the desired unit of measurement. CALIBRATION LOCK Press the CAL key a third time.
- Page 18 AUTO SEND Press the CAL key a fourth time. The T-Mike ES will display the status of the Auto Send (On/Off) function. Press any key except the 5/CAL key to toggle On/Off. Pressing the CAL key a final time completes the SETUP procedure and returns the T-Mike ES to the measurement...

ON / OFF FUNCTION The ON/OFF key is used to power on or off the T-Mike ES. When turned on, the unit will display a reading of zero. The PROBE- ZERO function should be performed at this point, to compensate for any change in the transducer. After performing a PROBE- ZERO, the T-Mike ES is ready to measure. - Page 21 0.250 inch sample, so that a stable reading is achieved. Remove the probe, then press the CAL key, followed by the 0 key, then the CAL key twice, to enter the measurement mode. The T-Mike ES will use that last acquired reading to zero the transducer delay.
- Page 22 CAL key once more to exit the CAL mode. If the velocity displayed is NOT correct, press the CLEAR key. The unit will display a single underscore, ( _ ) prompting the operator to enter a velocity. Key in the correct velocity. The T-Mike ES will return to the measurement mode.
- Page 23 To activate the DIFFerence function, press the DIFF key. The T-Mike ES will briefly display “dIFF,” followed by “On,” then illuminate the LED above the DIFF key. The T-Mike ES will then display the last-entered target thickness. • To change the displayed value, press the CLEAR key. The unit will display a single underscore prompting the operator to enter a thickness value.
- Page 24 ENTERING DATA VIA THE KEYPAD When the T-Mike ES is waiting for the operator to enter a numeric value, a single underscore will appear in the right-most position of the display. As numeric keys are pressed the display digits will shift to the left as in a calculator. A decimal point is entered using...
- Page 25 Entering a large metric thickness presents a problem. 19.999 inches is approximately 508.00 mm, a value with too many digits to display on the T-Mike ES. Our solution is to allow the entry of all of the digits but as the most- significant digitis shifted off the left end of the display, the “+”...
- Page 26 • The T-Mike ES may be configured to automaticallysend 4 readings a second. For this to occur the Auto Send function must be set to the on position. See the Auto Send section in the Inital Setup. Upon complete of the SEND function, the T-Mike ES will return to the measurement mode.
- Page 27 The T-Mike ES comes standard with 4 AA alkaline batteries. The user may elect to use rechargeable NiCad AA batteries that can be inserted as a direct replacement of the alkaline cells. The NiCad batteries may be charged externally or in the T-Mike ES as described below.
- Page 28 To recharge the NiCad batteries in the T-Mike ES connect the optional battery charger to the combination DATA/CHARGER jack on the top end cap of the T-Mike ES. Full charging of the NiCad batteries will occur in approximately 14 hours.

Page 32: Helpful Hints On Operation
BACKLIGHT The T-Mike ES features a backlit LCD display. The display illuminates when an echo is detected. Using the backlight will significantly reduce battery life. Therefore, you may wish to deactivate the backlight when using the T-Mike ES in a well-lit environment. -
Page 34: Maintenance And Troubleshooting
TRANSDUCER AND CABLE Check the cable for cuts or punctures. Check if the connectors are on tightly. If the T-Mike ES always indicates an echo when the transducer is connected, look for a piece of metal jammed in the cross talk barrier of the transducer. The cross talk barrier is the line separating the two halves of the transducer. - Page 35 The keypad is easily field replaceable as a spare part. DISPLAY The LCD is made of glass and is one of the most fragile components of the T-Mike ES. It may break if dropped. This LCD must be replaced by a factory trained technician.
