temperature probe calibration

Move around the reflector so that the echo reaches a maximum angle of incidence corresponding to the point at this time is that the probes or the K-scale values. Material Velocity Calibration find R100mm described in accordance with a maximum reflected waves makes it possible to adjust the display range is displayed on the screen of the arc of the second echo select gate way for the double gate, A gate with an echo adjustment intersect, regulating B gate intersects with the second echo, adjust the speed of sound value makes the status line sound path tank calibration software is 100, velocity values ??obtained at this time is the actual velocity values ??of the material. Probe Zero calibration measurement state maintained above the gate way to the positive or negative, so that the state regulate the probe zero sound path measurement line again to 100, the probe zero value is zero at this time to get the value of the probe. There are many oblique probe calibration method does not completely block the test stick using standard calibration, the calibration may be performed using the known depth of the hole, in theory, the reference reflecting body is smaller, the higher the accuracy of calibration, but the calibration difficulty is correspondingly increased. When using the calibrated orifice by measuring the depth of the hole and the horizontal position, to calibrate the angle of the slope is calculated, and using the measured values ??of the depth or horizontal position of the probe velocity and zero calibration.
