Figure 11-39 Incorrectly triggered measurement
If this situation occurs, you can adjust the start position in time of the measurement
window by adjusting the start position of Gate 1.
To adjust the measurement window start position
Press GATES and increase or decrease the gate 1 start position.
11.9.4.3 Manual Gain Adjustment
While Automatic Gain Compensation (AGC) is recommended when measuring in the
Corrosion Module, some applications may require manual adjustment of gain to
achieve optimal results. Often this requirement is related to transducer sensitivity. If
the transducer sensitivity is low, the default initial gain for the transducer may not be
sufficient to allow measurements in AGC mode. If the transducer is overly sensitive,
or the test material is highly transmissive, the default initial gain may be too high and
result in amplified noise or cross talk, causing incorrect measurements.
To manually adjust the gain parameter
1. Choose Corrosn Setup > AGC (group 3/4).
