Setting The Probe Parameters - NOVOTEST UD3701 Operation Manual

2.4.4 Setting the probe parameters

Setting the probe parameters is made in «Probe» parameters group (Figure 2.15).
Following parameters should be set:
1. Probe type. Select parameter «DUAL» and set the correct type (single element «OFF» or dual
element «ON»).
2. Operating frequency of the probe «FREQ» (Figure 2.16).
Figure 2.16 – Setting the operating frequency of the probe - «FREQ» parameter
3. Delay in the prism of the probe «DELAY» (delay value in µs). While using the probe, delay
can change due to scuffing of the prism. Delay could be determined by standard calibration
blocks (see paragraph about calibration 2.5.1 or 2.5.2). Delay determination, using the
calibration block SO-2, is shown on Figure 2.17.
а) delay in the prism is 0 µs
