4. CALIBRATION OF NORMAL PROBE 4MHZ/DOUBLE CRYSTAL
Connect The O °/4mhz/ Double Crystal Probe
Select T-R Double Crystal Probe
Feed Required Range (For Example 200m.M)
Put O ° Probe On IIW(VI Block After Applying Couplant At 100M.M. Width Side
Set Delay And Probe Zero
Set First Reflected Peak At 5.0 Division On Horizontal Scale Using Delay Or Probe Zero. Adjust First Peak And PLACE GATE OVER IT And Read Beam Path,depth Shall Be 100M.M.
IIND Reflected Peak Will Be At 10 Division.
If Peak Is Not At 10.0 div,set It By Using Delay Or Probe Zero.
Thus, Your Equipment Is Calibrated For 200m.M. Rang
For Verify Calibration Put Probe On Top Of Railhead The Back Peak Position Will Be On 7.8 For 52kg Rail&8.6 For 60kg Rail
