4 Zero Calibration Set the Gain to 6.0dB .500.400.300.200.100Set the Gain to 6.0dBCouple the transducer to the in stepSet Gate 1 so that it surrounds the first backwall echo from the in stepUse Auto-XX to adjust the gain so that the signal is at 80%
5 Zero Calibration (cont.) Press the Auto CAL key to bring up the Calibration menuMake sure the CAL Mode is set to Thickness*(If more than just Gate 1 is active you will have other options for CAL Mode)Press [P3] for CAL ZeroEnter in the dialog boxPress the Check key to continue on to the Velocity calibration
6 Velocity Calibration Couple the transducer to the 0.500 in step .400.300.200.100Couple the transducer to the in stepSet Gate 1 so that it surrounds the first backwall echo from the in stepUse Auto-XX to adjust the gain so that the signal is at 80%
7 Velocity Calibration (cont.) Press [P2] for CAL VelocityEnter in the dialog boxUse the right arrow to scroll to Calculate and then press the Check key to complete the calibration*If you are ONLY doing a velocity calibration, press Check to continueAdjust the Range back to the starting value of in
8 Calibration Complete!Verify that your unit is properly calibrated by checking the thickness measurement at each step on the block.NOTE: Make sure to move the gate so it surrounds the first backwall echo for each step you are on.
