Page 6: Operating Instructions
Operating Instructions Insert the ultrasonic sensor into the probe connectors on the meter. Press the Power button to turn the meter on. The LCD will display "0" and the selected unit of measure. Initial Calibration Place a small drop of coupling gel (R7950) on the 5mm calibration test block. Press the CAL button and "CAL" will appear on the display. Place the sensor on the calibration test block while ensuring the coupling indicator appears on the display and the coupling LED turns on. - Page 7 "XXXX" is a 4-digit number that represents the sound velocity of the material that can be adjusted by the user (For entering and adjusting Sound Velocity please see "Setting the Sound Velocity for a known Material".

Page 8: Measuring Procedure
Measuring Procedure Once the material has been selected, follow steps 1 through 4 below to perform a measurement. While the meter is on, press the mm/inch button to select the cor- rect unit of measure. After applying coupling gel on the material, place the sensor firmly against the desired measurement area. - Page 9 Press the SELECT button to confirm your selection. The display will show "0" confirming the material has been selected. If you select a material code without confirming the selection the instrument will automatically resume normal operation after a few seconds. Press the VEL button and the display will show the last saved sound velocity measurement.

Press and hold the arrows to adjust the sound velocity value by 100m/s. -
Page 11: Measurement Methods
Measurement Methods There are three base measurement methods: Single measurement method: This method involves measuring the thickness at a single point. Double measurement method: This method involves performing two thickness measurements near a single spot rotating the ultrasonic sensor from 0 to 90° respectively, with respect to the split face (Fig.1).Take the smaller of the two indicated values as the thickness of the material. -
Page 12: Maintenance
Maintenance Cleaning the Test Piece After taking a measurement, clean the test pieces to prevent them from rusting. If the pieces are not being used for a long period of time coat them with oil to prevent rust. Protecting the Ultrasonic Sensor Be sure to clean the ultrasonic sensor and cable after each use. -
